# Phar->getMetaData

(no version information, might be only in CVS)

Phar->getMetaData -- Returns phar archive meta-data

## 说明

int Phar->getMetaData ( void )

## 参数

## 返回值

any PHP variable that can be serialized and is stored as meta-data for the Phar archive, or `NULL` if no meta-data is stored.

## 范例

例 1. A Phar->getMetaData() example

`<?php // make sure it doesn't exist @unlink('brandnewphar.phar'); try { $p = new Phar(dirname(__FILE__) . '/brandnewphar.phar', 0, 'brandnewphar.phar'); } catch (Exception $e) { echo 'Could not create phar:', $e; } $p['file.php'] = '<?php echo "hello";'; $p->setMetaData(array('bootstrap' => 'file.php')); var_dump($p->getMetaData()); ?>`

上例将输出：

    array(1) {
      ["bootstrap"]=>
      string(8) "file.php"
    }
