Phar->setMetaData — Sets phar archive meta-data
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.
Any PHP variable containing information to store that describes the phar archive
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;
}
?>
El resultado del ejemplo seria:
array(1) { ["bootstrap"]=> string(8) "file.php" }
