function fread() problem..

[Rekcuf]

Hello..

Function fread() failed When I was trying to get contents from a file larger than 10MB. Here is my code:

...
$fp = fopen("./exampleFile.ext", "rb");
flock($fp, 3);
$contents = fread($fp, filesize("./exampleFile.ext"));
fclose();
...

I got an error page. The browser said:

This page cannot be displayed.
...
The server cannot be found or DNS error.
Internet Explorer
...

When I used:

...
$fp = fopen("./exampleFile.ext", "rb");
flock($fp, 3);
while (!feof($fp)) {
    echo fread($fp, 1024);
}
fclose();
...

It worked!

But....

...
$contents = "";
$fp = fopen("./exampleFile.ext", "rb");
flock($fp, 3);
while (!feof($fp)) {
    $contents .= fread($fp, 1024);
}
fclose();
...

can't work...

why?

Check your php.ini file; there is a setting there that limits how much memory PHP is allowed to use. Its default value is 8MB.

Thanks..

But if I wanna read a file larger than the memory setting in the php.ini without modifying php.ini, what can I do?

You can set it in httpd.conf (at least on Apache). Have the same effect as setting it in php.ini: affects every script used by everyone on that server.

It's not something that can be done on a per-directory or per-script basis.
