[SOLVED] File Read Issue

[glenelkins]

Hi

 

Im writing a program to enable a user to select a part of an MP3 song and save it. Now I wrote a quick test before I started on the final app, and that worked fine.

 

Here is the test page code

<?
ob_start();


// Open the mp3
$open_file = fopen( "1.mp3", "r");

// Take first 20 seconds assuming bitrate of 1
/* Time worked out as:
 * ( 128kbits * 1024 / 8 ) * 20 = 320000;
*/

$content = fread( $open_file, 320000 );

fclose( $open_file );

echo ( "<b>WE ARE LOOKING AT 20seconds OF 1.mp3</b>" );
echo ( "<br><br><br>" );
echo ( $content );

$open_file = fopen ( "2.mp3", "w" );

fwrite ( $open_file, $content );

fclose ( $open_file );

//header ( "Location: 2.mp3" );


?>

 

This works perfect, it writes the 2.mp3 file fine with the correct number of seconds. here is the code from the main app. this one when i comes to reading the file seems to go and download the index.php file its running from rather than just opening the mp3 file...any ideas on this?

 

<?php
ob_start();

// Mp3 Splitting

if ( $_GET['aCt'] != "upload" ) {

// Show the user the upload form
$CONTENT = <<<TPL
<form action="index.php?aCt=upload" method="post" enctype="multipart/form-data">
<table border="0" align="center" cellpadding="0" cellspacing="2">
