Phar::setMetadata

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

Phar::setMetadataSets phar archive meta-data

说明

public void Phar::setMetadata ( mixed $metadata )

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"
}
