Require all files in a folder

Question

Is there an easy way to programmatically require all files in a folder?

Answer 1

Simple:

foreach(glob("path/to/my/dir/*.php") as $file){
    require $file;
}

Answer 2

My way to require all siblings:

<?php
$files = glob(__DIR__ . '/*.php');
foreach ($files as $file) {
    // prevents including file itself
    if ($file != __FILE__) {
        require($file);
    }
}

Answer 3

Solution using opendir, readdir, closedir. This also includes subdirectories.

<?php
function _require_all($path, $depth=0) {
    $dirhandle = @opendir($path);
    if ($dirhandle === false) return;
    while (($file = readdir($dirhandle)) !== false) {
        if ($file !== '.' && $file !== '..') {
            $fullfile = $path . '/' . $file;
            if (is_dir($fullfile)) {
                _require_all($fullfile, $depth+1);
            } else if (strlen($fullfile)>4 && substr($fullfile,-4) == '.php') {
                require $fullfile;
            }
        }
    }

    closedir($dirhandle);
}        

//Call like
_require_all(__DIR__ . '/../vendor/vlucas/phpdotenv/src');
