Find full file name from part of it [duplicate]

Question

This question already has answers here:

How can i check if file exists based on a partial file name? (2 answers)

Closed 9 years ago.

I have a directory that include debian packages and looks like that:

inside Depiction folder i have a Description for each package, each folder contains an index.php file

Inside that description page, i'm trying to find a way to get the full filename of the deb by only having the first part of the file com.name.app1 and it will automatically get the second part.

The reason i'm trying to do this, its because i will have to update the debian packages later and i don't want to edit the description page every time i update a package

And the filename i'm using it for some counter/filesize and other scripts

Thanks in advance

Using glob and regex with preg_match you can find the files:

<?php

     // define which app
    $app = "app1";

    // Search the directory for possible matches
        foreach (glob("/com.name.".$app."*") as $filename) {
            $filename . "\n";

            preg_match('/\\d\\.\\d-\\d_.*\\.deb/', $filename, $matches);
            echo "filename: com.name.".$app."_{$matches[0]}\n";
        }
?>

Result:

com.name.app1_1.0-1_iphoneos-arm.deb
