PHP 8.4.0 RC4 available for testing

var_export

(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)

var_exportBir değişkenin çözümlenebilir dizge gösterimini döndürür veya çıktılar

Açıklama

var_export(mixed $ifade, bool $döndür = false): ?string

var_export() işlevi belirtilen değişken hakkında yapı bilgisi döndürür. Dönen gösterimin geçerli bir PHP kodu olması dışında var_dump() işlevine benzer.

Bağımsız Değişkenler

ifade

Bilgi edinmek istenen değişken.

döndür

true belirtilmişse, var_export() işlevi değişken gösterimini çıktılamak yerine döndürür.

Bilginize:

Bu işlev bu bağımsız değişken ile bir dahili çıktı tamponu kullanır, dolayısıyla ob_start() geriçağırım işlevinin içinde kullanılamaz.

Dönen Değerler

döndür bağımsız değişkeninde true belirtildiğinde değişkenin gösterimini döndürür. Aksi takdirde null döndürür.

Sürüm Bilgisi

Sürüm: Açıklama
8.2.0 Dışa aktarılan sınıf adları artık tamamen niteleniyor, evvelce baştaki ters eğik çizgi konulmazdı.
7.3.0 Artık stdClass nesneleri, mevcut olmayan stdClass::__setState() yöntemini kullanmak yerine nesneye dönüştürülmüş bir dizi olarak ((object) array( ... )) dışa aktarılıyor. Bunun uygulamadaki etkisi, stdClass'ın dışa aktarılabilmesi ve ortaya çıkan kodun PHP'nin önceki sürümlerinde bile çalışabilmesidir.

Örnekler

Örnek 1 - var_export() örnekleri

<?php
$a
= array (1, 2, array ("a", "b", "c"));
var_export($a);
?>

Yukarıdaki örneğin çıktısı:

array (
  0 => 1,
  1 => 2,
  2 =>
  array (
    0 => 'a',
    1 => 'b',
    2 => 'c',
  ),
)
<?php

$b
= 3.1;
$v = var_export($b, true);
echo
$v;

?>

Yukarıdaki örneğin çıktısı:

3.1

Örnek 2 - stdClass'ın dışa aktarılması (PHP 7.3.0'den beri)

<?php
$person
= new stdClass;
$person->name = 'ElePHPant ElePHPantsdotter';
$person->website = 'https://php.net/elephpant.php';

var_export($person);

Yukarıdaki örneğin çıktısı:

(object) array(
   'name' => 'ElePHPant ElePHPantsdotter',
   'website' => 'https://php.net/elephpant.php',
)

Örnek 3 - Sınıfların dışa aktarılması

<?php
class A { public $var; }
$a = new A;
$a->var = 5;
var_export($a);
?>

Yukarıdaki örneğin çıktısı:

A::__set_state(array(
   'var' => 5,
))

Örnek 4 - __set_state() kullanımı

<?php
class A
{
public
$var1;
public
$var2;

public static function
__set_state($an_array)
{
$obj = new A;
$obj->var1 = $an_array['var1'];
$obj->var2 = $an_array['var2'];
return
$obj;
}
}

$a = new A;
$a->var1 = 5;
$a->var2 = 'foo';

eval(
'$b = ' . var_export($a, true) . ';'); // $b = A::__set_state(array(
// 'var1' => 5,
// 'var2' => 'foo',
// ));
var_dump($b);
?>

Yukarıdaki örneğin çıktısı:

object(A)#2 (2) {
  ["var1"]=>
  int(5)
  ["var2"]=>
  string(3) "foo"
}

Notlar

Bilginize:

resource türündeki değişkenler bu işlev ile çıktılanamaz.

Bilginize:

var_export() işlevi, döngüsel gönderimler için PHP'nin çözümlenebilir bir kod üretmesi imkansıza yakın olduğundan bu tür döngüler işleme sokulmaz. Bir dizi veya nesnenin dizgesel gösterimi üzerinde işlemler yapmak istiyorsanız serialize() işlevini kullanın.

Uyarı

PHP 8.2.0 öncesinde, var_export() nesneleri dışa aktarırken, azami uyumluluk için, isim alanlı sınıfların sınıf ismine baştaki ters eğik çizgileri dahil etmiyordu.

Bilginize:

var_export() tarafından üretilen kodu değerlendirebilmek için, işlenen tüm nesnelerin sihirli __set_state yöntemini gerçeklemesi gerekir. Tek istisnası, nesneye dönüştürülmüş bir dizi kullanılarak dışa aktarılan stdClass'tır.

Ayrıca Bakınız

  • print_r() - Bir değişkenin insanlarca okunabilecek gösterimini basar
  • serialize() - Bir değerin saklanabilir bir gösterimini üretir
  • var_dump() - Bir değişkenle ilgili bilgiyi dökümler

It doesn't appear to be documented, but the behaviour of `var_export()` changed in PHP 7.

Previously, `var_export(3.)` returned "3", now it returns "3.0".

Looks like since version 5.4.22 var_export uses the serialize_precision ini setting, rather than the precision one used for normal output of floating-point numbers.
As a consequence since version 5.4.22 for example var_export(1.1) will output 1.1000000000000001 (17 is default precision value) and not 1.1 as before.

<?php
//ouput 1.1000000000000001
var_export(1.1)
?>

I learned the hard way that if var_export encounters a resource handle it exports it as "NULL", even if it is a valid handle. The documentation states that a handle cannot be exported, but it does not describe what happens if you try to do so anyway.

I had been using var_export in some debugging code while tracing a problem with a resource handle not being generated and ended up thinking that null handles were still being generated long after the problem had been fixed.

I found that my complex type was exporting with
stdClass::__set_state()
in places. Not only was that strange and messy, it cannot be eval()-ed back in at all. Fatal error. Doh!

However a quick string-replace tidy-up of the result rendered it valid again.

$macro = var_export($data, TRUE);
$macro = str_replace("stdClass::__set_state", "(object)", $macro);
$macro = '$data = ' . $macro . ';';

And now the string I output *can* be evaluated back in again.

Try this function instead of var_export($GLOBALS) or var_dump($GLOBALS) when all you want to know is the values of the variables you set on the current page.

<?php
function globalvars(){
$result=array();
$skip=array('GLOBALS','_ENV','HTTP_ENV_VARS',
'_POST','HTTP_POST_VARS','_GET',
'HTTP_GET_VARS',
'_COOKIE',
'HTTP_COOKIE_VARS','_SERVER',
'HTTP_SERVER_VARS',
'_FILES','HTTP_POST_FILES',
'_REQUEST','HTTP_SESSION_VARS',
'_SESSION');
foreach(
$GLOBALS as $k=>$v)
if(!
in_array($k,$skip))
$result[$k]=$v;
return
$result;
}
//functionglobalvars

var_export(globalvars());

<roman at DIESPAM dot feather dot org dot ru>, your function has inefficiencies and problems. I probably speak for everyone when I ask you to test code before you add to the manual.

Since the issue of whitespace only comes up when exporting arrays, you can use the original var_export() for all other variable types. This function does the job, and, from the outside, works the same as var_export().

<?php

function var_export_min($var, $return = false) {
if (
is_array($var)) {
$toImplode = array();
foreach (
$var as $key => $value) {
$toImplode[] = var_export($key, true).'=>'.var_export_min($value, true);
}
$code = 'array('.implode(',', $toImplode).')';
if (
$return) return $code;
else echo
$code;
} else {
return
var_export($var, $return);
}
}

When it comes to HTML output (as discussed below), it's all fun and games until someone pokes their eye out with a "<".

Surround it with "<pre>", but do remember to wrap it in htmlspecialchars() as well.

Just for fun, trying to understand the definition of "returns parsable string"....any type of variable passed to var_export, the return value will be a typecasted as string...

<?php

$var
= 1;
var_dump($var); //type is int as expected
echo "<br>";
$var_after_export = var_export($var,true); //returning $var will now makes it a string
var_dump($var_after_export);

I didn't see this simple little item anywhere in the user notes. Maybe I'm blind!

Anyway, var_export and print_r both use spaces and carriage returns for formatting. Sent to an html page, most of the formatting is lost. This simple function prints a nicely formatted array to an html screen:

<?php
function pretty_var($myArray){
print
str_replace(array("\n"," "),array("<br>","&nbsp;"), var_export($myArray,true))."<br>";
}
?>

Like previously reported, i find var_export() frustrating when dealing with recursive structures. Doing a :

<?php
var_export
($GLOBALS);
?>

fails. Interestingly, var_dump() has some logic to avoid recursive references. So :

<?php
var_dump
($GLOBALS);
?>

works (while being more ugly). Unlike var_export(), var_dump() has no option to return the string, so output buffering logic is required if you want to direct the output.

(This replaces my note of 3-July-2009. The original version produced no output if a variable contained an empty array, or an array consisting only of empty arrays. For example, $bigarray['x'] = array(); Also, I have added a second version of the function.)

The output can be difficult to decipher when looking at an array with many levels and many elements on each level. For example:

<?php
print ('$bigarray = ' . var_export($bigarray, true) . "\n");
?>

will return:

$bigarray = array(
... (500 lines skipped) ...
'mod' => 'charlie',

Whereas the routine below can be called with:

<?php
recursive_print
('$bigarray', $bigarray);
?>

and it will return:

$bigarray = array()
... (500 lines skipped) ...
$bigarray['foo']['bar']['0']['somethingelse']['mod'] = 'charlie'

Here's the function:

<?php
function recursive_print ($varname, $varval) {
if (!
is_array($varval)):
print
$varname . ' = ' . $varval . "<br>\n";
else:
print
$varname . " = array()<br>\n";
foreach (
$varval as $key => $val):
recursive_print ($varname . "['" . $key . "']", $val);
endforeach;
endif;
}
?>

For those who want a version that produces valid PHP code, use this version:

<?php
function recursive_print ($varname, $varval) {
if (!
is_array($varval)):
print
$varname . ' = ' . var_export($varval, true) . ";<br>\n";
else:
print
$varname . " = array();<br>\n";
foreach (
$varval as $key => $val):
recursive_print ($varname . "[" . var_export($key, true) . "]", $val);
endforeach;
endif;
}
?>

If your output is to a text file and not an HTML page, remove the <br>s.

I have been looking for the best method to store data in cache files.

First, I've identified two limitations of var_export verus serialize. It can't store internal references inside of an array and it can't store a nested object or an array containing objects before PHP 5.1.0.

However, I could deal with both of those so I created a benchmark. I used a single array containing from 10 to 150 indexes. I've generate the elements' values randomly using booleans, nulls, integers, floats, and some nested arrays (the nested arrays are smaller averaging 5 elements but created similarly). The largest percentage of elements are short strings around 10-15 characters. While there is a small number of long strings (around 500 characters).

Benchmarking returned these results for 1000 * [total time] / [iterations (4000 in this case)]

serialize 3.656, 3.575, 3.68, 3.933, mean of 3.71
include 7.099, 5.42, 5.185, 6.076, mean of 5.95
eval 5.514, 5.204, 5.011, 5.788, mean of 5.38

Meaning serialize is around 1 and a half times faster than var_export for a single large array. include and eval were consistently very close but eval was usually a few tenths faster (eval did better this particular set of trials than usual). An opcode cache like APC might make include faster, but otherwise serialize is the best choice.

var_export() differs from print_r() for variables that are resources, with print_r() being more useful if you are using the function for debugging purposes.
e.g.
<?php
$res
= mysql_connect($dbhost, $dbuser, $dbpass);
print_r($res); //output: Resource id #14
var_export($res); //output: NULL
?>

A small function for exporting variables as string, supporting nested arrays, with indented output, blockquoted and with double quotes, that can be pasted back in code.

<?php
function dump($value) {
function
_dump($value, $indent = 0) {
if (!
is_array($value)) return json_encode($value, JSON_NUMERIC_CHECK);
foreach(
$value as $key => $item) $result .= (ifset($result) ? ",\r\n" . str_repeat(" ", $indent + 2) : "") . json_encode($key) . " => " . _dump($item, $indent + 2);
return
"[\r\n" . str_repeat(" ", $indent + 2) . "$result\r\n" . str_repeat(" ", $indent) . "]";
}
return
"<pre>" . htmlspecialchars(_dump($value)) . "</pre>";

True, but that method would require you to open and read the file into a variable and then unserialize it into another variable.

Using a file created with var_export() could simply be include()'d, which will be less code and faster.

[kaja]
If you are trying to find a way to temporarily save variables into some other file, check out serialize() and unserialize() instead - this one is more useful for its readable property, very handy while debugging.

[original post]
If you're like me, you're wondering why a function that outputs "correct PHP syntax" is useful. This function can be useful in implementing a cache system. You can var_export() the array into a variable and write it into a file. Writing a string such as

<?php
$string
= '<?php $array = ' . $data . '; ?>';
?>

where $data is the output of var_export() can create a file that can be easily include()d back into the script to recreate $array.

The raw output of var_export() could also be eval()d to recreate the array.

NOTE: If an object Foo has __set_state() method, but if that object contains another object Bar with no __set_state() method implemented, the resulting PHP expression will not be eval()-able.

This is an example (object Test that contains an instance of Exception).

<?php

class Test
{
public
$one;
public
$two;
public function
__construct($one, $two)
{
$this->one = $one;
$this->two = $two;
}
public static function
__set_state(array $array)
{
return new
self($array['one'], $array['two']);
}
}

$test = new Test('one', new Exception('test'));

$string = var_export($test, true);

/* $string =
Test::__set_state(array(
'one' => 'one',
'two' =>
Exception::__set_state(array(
'message' => 'test',
'string' => '',
'code' => 0,
'file' => 'E:\\xampp\\htdocs\\test.Q.php',
'line' => 35,
'trace' =>
array (
),
'previous' => NULL,
)),
))
*/

eval('$test2 = '.$string.';'); // Fatal error: Call to undefined method Exception::__set_state

?>

So avoid using var_export() on a complex array/object that contains other objects. Instead, use serialize() and unserialize() functions.

<?php

$string
= 'unserialize('.var_export(serialize($test), true).')';

eval(
'$test2 = '.$string.';');

var_dump($test == $test2); // bool(true)

?>

If you call var_export() on an instance of stdClass, it attempts to export it using ::__set_state(), which, for some reason, is not implemented in stdClass.

However, casting an associative array to an object usually produces the same effect (at least, it does in my case). So I wrote an improved_var_export() function to convert instances of stdClass to (object) array () calls. If you choose to export objects of any other class, I'd advise you to implement ::__set_state().

<?php
/**
* An implementation of var_export() that is compatible with instances
* of stdClass.
* @param mixed $variable The variable you want to export
* @param bool $return If used and set to true, improved_var_export()
* will return the variable representation instead of outputting it.
* @return mixed|null Returns the variable representation when the
* return parameter is used and evaluates to TRUE. Otherwise, this
* function will return NULL.
*/
function improved_var_export ($variable, $return = false) {
if (
$variable instanceof stdClass) {
$result = '(object) '.improved_var_export(get_object_vars($variable), true);
} else if (
is_array($variable)) {
$array = array ();
foreach (
$variable as $key => $value) {
$array[] = var_export($key, true).' => '.improved_var_export($value, true);
}
$result = 'array ('.implode(', ', $array).')';
} else {
$result = var_export($variable, true);
}

if (!
$return) {
print
$result;
return
null;
} else {
return
$result;
}
}

// Example usage:
$obj = new stdClass;
$obj->test = 'abc';
$obj->other = 6.2;
$obj->arr = array (1, 2, 3);

improved_var_export((object) array (
'prop1' => true,
'prop2' => $obj,
'assocArray' => array (
'apple' => 'good',
'orange' => 'great'
)
));

/* Output:
(object) array ('prop1' => true, 'prop2' => (object) array ('test' => 'abc', 'other' => 6.2, 'arr' => array (0 => 1, 1 => 2, 2 => 3)), 'assocArray' => array ('apple' => 'good', 'orange' => 'great'))
*/
?>

Note: This function spits out a single line of code, which is useful to save in a cache file to include/eval. It isn't formatted for readability. If you want to print a readable version for debugging purposes, then I would suggest print_r() or var_dump().

When trying to use __set_state() to rebuild a huge, tricky class use the following:

class Foo
{
public $a;
public $b;
public $c;
public $d;
public $e;
public $f;
public $g;
public $h;
public $i;

public function __set_state($array)
{
$obj = new ArrayConfig;
foreach($array as $k => $v) {
eval('$obj->'.$k.' = '.$v.';');
}
return $obj;
}
}

This will return a reconstructed version of the class without having to manually type each individual object in the class manually (as shown in the __set_state() example)

To work around that problem, I created my own var_export, which also uses a more compact format, and using [] for arrays:

<?php
function var_export3($var, $indent = '') {
if (
is_array($var)) {
$indent .= ' ';
$ret = '';
$i = 0;
$is_num = true;
foreach (
$var AS $idx => $value) {
if (
$ret != '')
$ret .= ",\n";
if (
$is_num && $idx === $i) {
$i++;
$ret .= $indent.var_export3($value, $indent);
} else {
$is_num = false;
$ret .= $indent.var_export3($idx).'=>'.var_export3($value, $indent);
}
}
if (
$ret == '')
return
"[]";
return
"[\n".$ret."]";
} else if (
is_bool($var)) {
return
$var ? 'true' : 'false';
} else if (
is_int($var) || is_float($var)) {
return
$var;
} else if (
is_string($var)) {
if (
$var === (string)(float)$var)
return
$var;
return
"'".str_replace(["\0", '\\', '\''], ["\\0", '\\', '\\\''], $var)."'";
} else if (
is_object($var)) {
$class = get_class($var);
if (
$class == 'stdClass') {
$prefix = ;
return
"(object)".var_export3((array)$var, $indent);
} else {
return
"$class::__set_state(".var_export3((array)$var, $indent).')';
}
}
}

echo
var_export3($t)."\n";
Result:
Test::__set_state([
'\0Test\0priv'=>'Private Info',
'\0*\0prot'=>'Protected Info',
'pub'=>'Public Info',
'\0TestParent\0priv'=>'Parent Private'])
?>
Note that replacement for non-printable characters is not complete.
