示例

示例 #1 A PharFileInfo::getMetadata() example

<?php
// make sure it doesn't exist
@unlink('brandnewphar.phar');
try {
    $p = new Phar(dirname(__FILE__) . '/brandnewphar.phar', 0, 'brandnewphar.phar');
    $p['file.txt'] = 'hello';
    $p['file.txt']->setMetadata(array('user' => 'bill', 'mime-type' => 'text/plain'));
    var_dump($p['file.txt']->getMetadata());
} catch (Exception $e) {
    echo 'Could not create/modify brandnewphar.phar: ', $e;
}
?>

以上示例会输出：

array(2) {
  ["user"]=>
  string(4) "bill"
  ["mime-type"]=>
  string(10) "text/plain"
}
