Description
final public static bool Phar::mapPhar ([ string $alias [, int $dataoffset = 0 ]] )
This static method can only be used inside a Phar archive's loader stub in order to initialize the phar when it is directly executed, or when it is included in another script.
Parameters
-
alias -
The alias that can be used in phar:// URLs to refer to this archive, rather than its full path.
-
dataoffset -
Unused variable, here for compatibility with PEAR's PHP_Archive.
Return Values
Returns TRUE on success or FALSE on failure.
Errors/Exceptions
PharException is thrown if not called directly within PHP execution, if no __HALT_COMPILER(); token is found in the current source file, or if the file cannot be opened for reading.
Examples
Example #1 A Phar::mapPhar() example
mapPhar should be used only inside a phar's loader stub. Use loadPhar to load an external phar into memory.
Here is a sample Phar loader stub that uses mapPhar.
<?php
function __autoload($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');
}
