</pre>



I recommend changing:

<pre>

print(fread($fh, filesize($file)));

</pre>

to:

<pre>

while (!feof($fh)) {

    print fread($fh, 8192);

}

</pre>



This keeps it from loading the whole movie into memory (bad for large videos)



Wouldn't just

<pre>

print(fread($fh, 8192));

</pre>

be enough, as we are already in a

<pre>

while (!feof($fh)) {

</pre>

loop from further up?

<br/>

<br />

<p>Um,</p>
