About php memory_limit
<p>My system memory is 128M and set memory_limit to 128M, can use php fread to download files over 150M size?
    I tried not! 
    Can be downloaded only 110M around!</p>

<p>thanks all,</p>

<pre><code>    $sent = 0;
    $blocksize=(2 &lt;&lt; 20);

    $fp = fopen($download_path, "rb");
    while($sent &lt; $size){
        echo fread($fp, $blocksize);
        $sent += $blocksize;
    }
    exit(0);
</code></pre>

<p>I use this way, so how should I do?</p>
