PHP 7.0.6 Released

    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(); ?>"

    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.
