Display all files in directory beginning with A

Expand Post »

Hi all,

I've tried searching both here and google for help on this one. I'm not quite sure what to call it basically I have a directory with different files all .txt. I want to display only the ones beginning with letter A. How do I modify my below code to do this?

PHP Syntax (Toggle Plain Text)
<?php
if ($handle = opendir('poems/')) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
            echo "$file\n <br />";
        }
    }
    closedir($handle);
}
?>
<?php
if ($handle = opendir('poems/')) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
            echo "$file\n <br />";
        }
    }
    closedir($handle);
}
?>

I know I need to use something like A* but I don't even know what to call it to search for it?

Thanks!

As a short explanation strings are arrays of characters so if you want to get the 3rd letter in a string just do $string[2] (counting begines at 0)
