PHP file writing problem

Question

I'm trying to write to a file in PHP to cache the output of a small portion of code.

        ob_start();
        echo "Hello";
     $fp = fopen("cache/ttcache.php", 'w');
        fwrite($fp, ob_get_contents());
        fclose($fp);
        ob_end_flush();

The file exists and is blank. The fwrite function points to the correct location. It just doesn't write.

Any help?

Can you show some minimal code that reproduces the problem? Something that actually produces output, i.e. where the // my code that creates an output is filled in. — deceze

ob_get_contents() holds the correct data, I just checked it out. — AKor

Try to write first small word or sentence first.

fwrite($fp, 'hello')

Also check your file permission's should be writable.

It doesn't write a word, I think you're correct in that this is a permissions problem. I'll make it writable if it isn't.

Make sure ob_get_contents() is really not empty. Then try

fflush($fp);

right before fclose().
