列出带有前缀的特定文件

Question

Hi I would like to list all specific files with the prefix myfile-..

This is my current code... and no files are listed

   <select name="s1">
        <option value="" selected="selected">-----</option>
        <?php 
            foreach(glob(dirname(__FILE__) . '/*') as $filename){
                $filename = basename($filename);
               // if (preg_match('/\.(php)$/i', $filename)) {
                    if (preg_grep('~^myfile-.*\.php$~', $filename)) {
                    echo "<option value='" . $filename . "'>".$filename."</option>";
                }
            }
        ?>

if I use this... all files are listed

 if (preg_match('/\.(php)$/i', $filename)) {

while no files are listed if using this

if (preg_grep('~^myfile-.*\.php$~', $filename)) {

Answer 1

Why make it so hard?

If(substr($filename, 0, 7) == "myfile-"){
    echo "<option value='" . $filename . "'>".$filename."</option>";
}

Substr looks at the first seven characters and looks if it's "myfile-"

Answer 2

Shortest way:

foreach (glob(dirname(__FILE__)."myfile-*.php") as $filename) {
        echo "<option value='" . $filename . "'>".$filename."</option>";
    }
