PharFileInfo::hasMetadata is a method in PHP's Phar extension used to check if a particular file in a Phar archive contains metadata. Metadata in a Phar file can be set using the Phar::setMetadata method during the creation or modification of the Phar archive.

The PharFileInfo::hasMetadata method takes no parameters and returns a boolean value. It returns true if the file has metadata associated with it, otherwise, it returns false.

Here's an example of how to use PharFileInfo::hasMetadata:

php
$phar = new Phar('archive.phar');
$file = $phar->offsetGet('file.txt');

if ($file->hasMetadata()) {
echo 'The file contains metadata.';
} else {
echo 'The file does not have any metadata.';
}


In this example, we create a new Phar object representing an existing Phar archive called 'archive.phar'. We then use the offsetGet method to retrieve a PharFileInfo object representing a file named 'file.txt' within the archive.

Next, we use the hasMetadata method of the PharFileInfo object to check if the file has any associated metadata. If it does, we print a message indicating that the file contains metadata. Otherwise, we print a message indicating that the file does not have any metadata.
