    I was curious as to how many line of code i had in my various projects. my projects usually span multipule directories so i needed to build-in directory walking. this function came as a result.

    By : mydimension

    <?php
    /*
    What it counts: all lines containing a semi-colon and all lines containing either an opened brace or a closed brace BUT NOT both.
    What it dosen't count: lines terminated by a newline.
    Syntax:
    int countCodeLines( string $directory )
    */
    function countCodeLines ($directory) {
    $curDir = getcwd();
    chdir($directory);

    static $totalCodeLines;
    $dir = opendir($directory);

    while ($item = readdir($dir)) {
    if ((is_dir($item)) && ($item != ".") && ($item != "..")) { //check to see if we need to walk into another directory
    countCodeLines(realpath($item)); //recursive directory walking
    } elseif (strrchr($item, ".") == ".php") { //count only php files
    $lines = file($directory . "/" . $item);

    foreach ($lines as $line) {
    //count lines containg a semi-colon or
    //lines containing either an opened brace or a closed brace BUT NOT both
    if (preg_match("/\;/", $line) xor (preg_match("/\{/", $line) xor preg_match("/\}/", $line))) {
    $totalCodeLines++;
    }
    }
    }
    }
    chdir($curDir);
    return $totalCodeLines; //return the final count
    }
    ?>
