Phar::setStub

(PHP >= 5.3.0, PECL phar >= 1.0.0)

Phar::setStubUsed to set the PHP loader or bootstrap stub of a Phar archive

Description

bool Phar::setStub ( string $stub )

Note:

This method requires the php.ini setting phar.readonly to be set to 0 in order to work for Phar objects. Otherwise, a PharException will be thrown.

This method is used to add a PHP bootstrap loader stub to a new Phar archive, or to replace the loader stub in an existing Phar archive.

The loader stub for a Phar archive is used whenever an archive is included directly as in this example:

<?php
include 'myphar.phar';
?>

The loader is not accessed when including a file through the phar stream wrapper like so:

<?php
include 'phar://myphar.phar/somefile.php';
?>

Parameters

stub

A string or an open stream handle to use as the executable stub for this phar archive.

Return Values

Returns TRUE on success or FALSE on failure.

Errors/Exceptions

UnexpectedValueException is thrown if phar.readonly is enabled in php.ini. PharException is thrown if any problems are encountered flushing changes to disk.

Examples

Example #1 A Phar::setStub() example

<?php
try {
    
$p = new Phar(dirname(__FILE__) . '/brandnewphar.phar'0'brandnewphar.phar');
    
$p['a.php'] = '<?php var_dump("Hello");';
    
$p->setStub('<?php var_dump("First"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>');
    include 
'phar://brandnewphar.phar/a.php';
    
var_dump($p->getStub());
    
$p['b.php'] = '<?php var_dump("World");';
    
$p->setStub('<?php var_dump("Second"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>');
    include 
'phar://brandnewphar.phar/b.php';
    
var_dump($p->getStub());
} catch (
Exception $e) {
    echo 
'Write operations failed on brandnewphar.phar: '$e;
}
?>

The above example will output:

string(5) "Hello"
string(82) "<?php var_dump("First"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>"
string(5) "World"
string(83) "<?php var_dump("Second"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>"

If your stub has a namespace, it is used for each include that doesn't define one.

One thing I had alot of problems with, is that i can't set the stub unless I put the whole operation inside of a try/catch block!

If i remove the try/catch block it will error our and not write the stub with the content i want it to have.
