Find Highest Numerically Named File

$latest = getNewest("/path/to/folder/*_bla.xml"); function getNewest($xmlfile){ foreach (glob($xmlfile) as $filename) { $c = explode('_', basename($filename)); $files[$c[0]] = $filename; } ksort($files, SORT_NUMERIC); $latest = array_pop($files); if (file_exists($latest)){ return $latest; } return false; }

In a folder are files named:
1_bla.xml
2_bla.xml
…
34_bla.xml

The function returns the file with the biggest numeric number:
$latest = “/path/to/folder/34_bla.xml”;
