Phar::setStub

Phar::setStub

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

Phar::setStub — Used to set the PHP loader or bootstrap stub of a Phar archive

Description

public bool Phar::setStub ( string $stub [, int $len = -1 ] )

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.

len

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( ?>"
