PHP List Files in Directory Excluding Index

March 3, 2014 Galaxy Internet Leave a comment

PHP List all files in a directory excluding the index file from the list.

Functions used are array_values, preg_grep, glob, foreach and basename.

$files = array_values(preg_grep('/^((?!index.php).)*$/', glob("*.php")));
foreach ($files as $filename)
    {
    echo "<li><a href=\"{$filename}\">".basename($filename, ".php")."</a></li>";
    }

$files = array_values(preg_grep('/^((?!index.php).)*$/', glob("*.php")));

foreach ($files as $filename)

{

echo "<li><a href=\"{$filename}\">".basename($filename, ".php")."</a></li>";

}

Another option using str_replace and !empty

<?php
foreach (glob("*.php") as $filename)
    {
    $filename = str_replace("index.php", '', $filename);
    if (!empty($filename))
        {
        echo "<li><a href=\"$filename\">" . basename($filename, ".php") . "</a></li>";
        }
    }
?>

<?php

foreach (glob("*.php") as $filename)

{

$filename = str_replace("index.php", '', $filename);

if (!empty($filename))

{

echo "<li><a href=\"$filename\">" . basename($filename, ".php") . "</a></li>";
