Examples

Example 1807. A Phar::mapPhar() example

mapPhar should be used only inside a phar's loader stub. Use loadPhar to load an external phar into memory.

Here is a sample Phar loader stub that uses mapPhar.

<?php
function __autoload($class)
{
   include
'phar://me.phar/' . str_replace('_', '/', $class) . '.php';
}
try {
   
Phar::mapPhar('me.phar');
   include
'phar://me.phar/startup.php';
} catch (
PharException $e) {
   echo
$e->getMessage();
   die(
'Cannot initialize Phar');
}
__HALT_COMPILER();
