错误／异常

范例

A Phar::delMetaData() example

<?php
try {
    $phar = new Phar('myphar.phar');
    var_dump($phar->getMetadata());
    $phar->setMetadata("hi there");
    var_dump($phar->getMetadata());
    $phar->delMetadata();
    var_dump($phar->getMetadata());
} catch (Exception $e) {
    // handle errors
}
?>

以上例程会输出：

NULL
string(8) "hi there"
NULL
