예제

Example #1 Phar::offsetGet() example

As with all classes that implement the ArrayAccess interface, Phar::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;
}
?>

위 예제의 출력:

file exists
Entry doesnotexist.txt does not exist
