Scripts List - PHP managed scripts list

scripts_list.php

<?php 
    // Default scripts
    $script_list = array(
        'vendor/jquery.js',
        'vendor/bootstrap.js',
        'vendor/video.js',
        '`videojs.options.flash.swf = "' . get_bloginfo('stylesheet_directory') . '/assets/swf/videojs.swf"',
        'global.js'
    );

    // Add custom scripts to your page
    // 
    // Usage:
    //   Set a var named $scripts as an array with path (relative from either the
    //   /assets/css dir or as a separate URL for external scripts) into the
    //   array in the order that you want. Code snippets can be added as well as
    //   long as the string starts with a backtick (`).
    // 
    // Example:
    //   $scripts = array('foo.js', '//bar.com/baz.js');
    // 
    // Additonal Features:
    //   Removing Scripts - If you want to remove a script that, you can do so by
    //                      prepending your script name with a bang ("!").
    //                     
    //                      Example:
    //                        $script = array('foo.js', '!bar.js');
    //                     
    //                      The example above will add the script "foo.js" and
    //                      remove the script "bar.js" if it was already going 
    //                      to be loaded.
    if (isset($scripts)) {
        foreach ($scripts as $script) {
            if (preg_match('/^\!/', $script)) {
                $index = array_search(substr($script,1), $script_list);
                if ($index) {
                    unset($script_list[$index]);
                }
            } else {
                array_push($script_list, $script);
            }
        }
    }

    foreach ($script_list as $script) {
        if (preg_match('/^`/', $script)) {
            echo '<script type="text/javascript">' . substr($script, 1) . '</script>';
        } else {
            if (preg_match('/^((http(s?):)?)\/\//', $script)) {
                echo "<script type=\"text/javascript\" src=\"$script\"></script>\n";
            } else {
                echo '<script type="text/javascript" src="'. get_bloginfo('stylesheet_directory') .'/assets/js/'. $script ."\"></script>\n";
            }
        }
    }

instead of echoing script tags, be better off using wp_enqueue_script
