Phar::setMetadata()
(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 1.0.0)
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
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"
}
