use Text::FrontMatter::YAML;

my $tfm = Text::FrontMatter::YAML->new( fh => main::DATA );
my $metadata = $tfm->get_frontmatter_hashref;

print qq(This is $metadata->{artist} with "$metadata->{title}":\n\n);
print $tfm->get_data_text;

PHP

<?php
$yaml = yaml_parse($metadata);
$yaml_copy = [];
foreach ($yaml as $k => $v) {
    // copy the data you wish to preserve to $yaml_copy
    if (...) {
        $yaml_copy[$k] = $yaml[$k];
    }
}
