Phar::hasMetadata() is a method in PHP's Phar extension that is used to check if a Phar archive has metadata associated with it.

Phar archives in PHP can be extended with metadata, which can contain additional information about the archive such as version numbers, author details, or any other custom data. The hasMetadata() method allows you to check if a Phar archive has any metadata attached to it.

Here's an example of how you can use Phar::hasMetadata():

php
$pharFile = 'path/to/archive.phar';
$phar = new Phar($pharFile);

if ($phar->hasMetadata()) {
echo "The Phar archive '{$pharFile}' has metadata.";
} else {
echo "The Phar archive '{$pharFile}' does not have any metadata.";
}


In the above example, we create a Phar object from the Phar archive file specified by $pharFile. We then use hasMetadata() to check if the archive has any metadata associated with it. If it does, we output a message indicating the presence of metadata. Otherwise, we output a message indicating the absence of metadata.

Please note that the hasMetadata() method was introduced in PHP 5.3.0. If you are using an older version of PHP, this method may not be available.
