explode

(PHP 4, PHP 5, PHP 7)

explodeSplit a string by a string

Descrierea

explode ( string $separator , string $string , int $limit = PHP_INT_MAX ) : array

Returns an array of strings, each of which is a substring of string formed by splitting it on boundaries formed by the string separator.

Parametri

separator

The boundary string.

string

The input string.

limit

If limit is set and positive, the returned array will contain a maximum of limit elements with the last element containing the rest of string.

If the limit parameter is negative, all components except the last -limit are returned.

If the limit parameter is zero, then this is treated as 1.

Notă:

Although implode() can, for historical reasons, accept its parameters in either order, explode() cannot. You must ensure that the separator argument comes before the string argument.

Valorile întoarse

Returns an array of strings created by splitting the string parameter on boundaries formed by the separator.

If separator is an empty string (""), explode() will return false. If separator contains a value that is not contained in string and a negative limit is used, then an empty array will be returned, otherwise an array containing string will be returned.

Exemple

Example #1 explode() examples

<?php
// Example 1
$pizza  "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces explode(" "$pizza);
echo 
$pieces[0]; // piece1
echo $pieces[1]; // piece2

// Example 2
$data "foo:*:1023:1000::/home/foo:/bin/sh";
list(
$user$pass$uid$gid$gecos$home$shell) = explode(":"$data);
echo 
$user// foo
echo $pass// *

?>

Example #2 explode() return examples

<?php
/* 
   A string that doesn't contain the delimiter will simply
   return a one-length array of the original string.
*/
$input1 "hello";
$input2 "hello,there";
$input3 ',';
var_dumpexplode','$input1 ) );
var_dumpexplode','$input2 ) );
var_dumpexplode','$input3 ) );

?>

Exemplul de mai sus va afișa:

array(1)
(
    [0] => string(5) "hello"
)
array(2)
(
    [0] => string(5) "hello"
    [1] => string(5) "there"
)
array(2)
(
    [0] => string(0) ""
    [1] => string(0) ""
)

Example #3 limit parameter examples

<?php
$str 
'one|two|three|four';

// positive limit
print_r(explode('|'$str2));

// negative limit (since PHP 5.1)
print_r(explode('|'$str, -1));
?>

Exemplul de mai sus va afișa:

Array
(
    [0] => one
    [1] => two|three|four
)
Array
(
    [0] => one
    [1] => two
    [2] => three
)

function aexplode($delimiters,$string,$trimduplicate = false) {
    if (!is_array($delimiters))
        return explode($delimiters,$string);
    $stringaux = str_replace($delimiters, $delimiters[0], $string);
    if ($trimduplicate)
        while (strpos($stringaux,$delimiters[0].$delimiters[0]) !== false)
            $stringaux = str_replace($delimiters[0].$delimiters[0],$delimiters[0],$stringaux);
    return explode($delimiters[0],$stringaux);
}

This functions will work and accept array.
