Function name must be a string issue

[max22]

Does anyone see anything wrong with this code?  It's an image upload/thumbnail script.

I get a Function name must be a string error on the last line of the code:

 

Code snippet:

 

$ou = imagecreatetruecolor($w, $h);

imagealphablending($ou, false);

$funcall = "imagecreatefrom$imtype";

imagecopyresampled($ou, $funcall($fromfile), 0, 0, 0, 0, $w, $h, $img[0], $img[1]);

$funcall = "image$outype";

$funcall($ou, 'uploaded/cache/' . $_GET['w'] . '-' . md5($fromfile));

}

$funcall($ou);          <----------- This throws the error, can't figure out why.

Why don't you try doing a var_dump( $funcall ) right before the offending line and see what's in the variable.

I should have mentioned, I tried that, and I tried:

 

echo $ou . '|' . $funcall;

 

but I get nothing at all from either one, like they're not even there.

Well I notice you have a closing bracket in the code you posted.  So maybe they're null.

I tried moving the last line above the } because what you said makes perfect sense.  Sure enough, no error anymore. 

 

Thanks so much!  I'm new here, but this place is great, talk about fast answers!
