opening files larger than 8 mb

[idm]

Whenever I try to open files larger than 8 mb in php, I get an eooro saying that I can't have more than 8 Mb in memory. I'm trying to copy a file from a [url]http://[/url] location using the code below.

$filez = fopen ($from_file, "r");
$fd = fopen($to_file, "w");
while (!feof ($filez)) {
$bf=fread($filez, 4096);
fputs($fd, $bf);
}
fclose($filez);
fclose($fd);

Please help me, or point me in the right direction. Thank you.

take a look to php.ini

;;;;;;;;;;;;;;;;;;;
; Resource Limits ;
;;;;;;;;;;;;;;;;;;;

max_execution_time = 30     ; Maximum execution time of each script, in seconds
memory_limit = 8M      ; Maximum amount of memory a script may consume (8MB)

May be this code needs less memory:

<?php
@unlink($to_file);
if (!copy($from_file, $to_file)) {
    print ("failed to copy file - Source: $from_file / Destination: $to_file<br>\n");
}
?>

The problem is that I can't modify the settings in php.ini, and I don't want to, because I don't understand what's eating up memory... I copy a block into a variable from a file, i dump the variable into a file, and do it all over again until the end of the source file, what's taking up memory?

Also, I can't use copy because I am opening a file from a webserver, with a path like http://some.server.ext/file.ext and I copy it to a local mirror.
