Sets phar archive meta-data

Phar::setMetadata

(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 1.0.0)

Phar::setMetadata — Sets phar archive meta-data

说明

public Phar::setMetadata ( mixed $metadata ) : void

Note:

此方法需要将 php.ini 中的 phar.readonly 设为 0 以适合 Phar 对象. 否则, 将抛出PharException.

Phar::setMetadata() should be used to store customized data that describes something about the phar archive as a complete entity. PharFileInfo::setMetadata() should be used for file-specific meta-data. Meta-data can slow down the performance of loading a phar archive if the data is large.

Some possible uses for meta-data include specifying which file within the archive should be used to bootstrap the archive, or the location of a file manifest like » PEAR's package.xml file. However, any useful data that describes the phar archive may be stored.

参数

metadata: Any PHP variable containing information to store that describes the phar archive

返回值

没有返回值。

范例

Example #1 A Phar::setMetadata() example

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

以上例程会输出：

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