dynamic array population

What's going on? Why won't this thing work? Can someone point out the error in this script? It fails on the lines where the $array1 array is used. Help!

<?php require("../includes/header.php"); ?>

<?php

$handle=opendir('./code/');
$array1=array();
echo "Available Scripts:<p>";
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != ".." && $file != "index.php") {
//add each file to an array so I can sort
foreach ( $file as $codefile ) {
$array1[] = $codefile;
}
}
closedir($handle);
}
//sort results of new array
$sortedarray = sort($array1);

//one last foreach loop, this time to display results of new array
foreach ( $sortedarray as $showcode ) {
echo "<a href=display.php?file=$showcode>";

$filename = (str_replace(".","(",$showcode));
echo $filename .")</a><br>n";

Here you go, give this a try:



Let me know how that goes....

Yes! It worked! I used the following script and it solved my problem, but I like the one you posted better since it was mostly my code (not lifted from someone else's page!) Thanks!

/************************8/

// populate array
$array_count = 0;
$songs = array();
//open dir
$handle=opendir('./code/');
echo "Available Scripts:<p>";

while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != ".." && $file != "index.php" && $file != "index2.php") {

$songs[$array_count]["filename"] = $file;
$array_count++;

}
}
closedir($handle);

//sort results of new array
sort($songs);

// output array
for ($i = 0; $i < $array_count; $i++)
{
$showcode = $songs[$i]["filename"];
echo "<a href=display.php?file=$showcode>";
$var = (str_replace("_"," ",$showcode));
$var = (str_replace("."," (",$var));
echo $var .")</a><br>n";
}
