Phar->setMetaData

(PECL phar:1.0.0-1.2.1)

Phar->setMetaData — Sets phar archive meta-data

说明

void Phar->setMetaData ( mixed $metadata )

setMetaData() should only 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 significantly slow down the performance of loading a phar archive if the data is large. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed.

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

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;
}
?>

上例将输出：

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