The following example shows accessing an external configuration file as if it were
a path within a phar archive.
First, the code inside of a phar archive:
<?php
$configuration = simplexml_load_string(file_get_contents(
Phar::running(false) . '/config.xml'));
?>
Next the external code used to mount the configuration file:
<?php
// first set up the association between the abstract config.xml
// and the actual one on disk
Phar::mount('phar:///path/to/archive.phar/config.xml', '/home/example/config.xml');
// now run the application
include '/path/to/archive.phar';
?>
Another method is to put the mounting code inside the stub of the phar archive.
Here is an example of setting up a default
configuration file if no user configuration is specified:
<?php
// first set up the association between the abstract config.xml
// and the actual one on disk
if (defined('EXTERNAL_CONFIG')) {
Phar::mount('config.xml', EXTERNAL_CONFIG);
if (file_exists(__DIR__ . '/extra_config.xml')) {
Phar::mount('extra.xml', __DIR__ . '/extra_config.xml');
}
} else {
Phar::mount('config.xml', 'phar://' . __FILE__ . '/default_config.xml');
Phar::mount('extra.xml', 'phar://' . __FILE__ . '/default_extra.xml');
}
// now run the application
include 'phar://' . __FILE__ . '/index.php';
__HALT_COMPILER();
?>
...and the code externally to load this phar archive:
<?php
define('EXTERNAL_CONFIG', '/home/example/config.xml');
// now run the application
include '/path/to/archive.phar';
?>
