Przykłady
Example #1 A Phar::offsetGet() example
As with all classes that implement the ArrayAccess interface, offsetGet is automatically called when using the [] angle bracket operator
<?php
$p = new Phar(dirname(__FILE__) . '/myphar.phar', 0, 'myphar.phar');
$p['exists.txt'] = "file exists\n";
try {
// automatically calls offsetGet()
echo $p['exists.txt'];
echo $p['doesnotexist.txt'];
} catch (BadMethodCallException $e) {
echo $e;
}
?>
