Esempi

Esempio 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('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;
}
?>

Il precedente esempio visualizzerà:

file exists
Entry doesnotexist.txt does not exist
