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" }
