Question

I have following error:

Error type – 2: preg_replace() [function.preg-replace]: Compilation failed: missing ) at offset 25: in /var/www/hosting/com/galerielaboratorio/scripts/functions.php on line 766

Here is the function:

function getThumbName($photo, $name = 'thumb') {

$ext = preg_replace ("/.*\./", "", $photo);
$photo = preg_replace ("/\.". $ext ."$/", "" , $photo). "." . $name . "." .$ext; // this line causes the error  

return $photo;

}

Thanks for help in advance.

Answer 1

Cannot read your expression, but you missed one ). ()-pairs define expression groups. One ( without its corresponding ) is just invalid (and thats what the error message tries to tell you). If you want to have a literal ( you must escape it \(

However, have a look at pathinfo(), explode() and str_replace(). This is not a scenario for regular expressions

$ext = pathinfo($photo, PATHINFO_EXTENSION);
$photo = basename($photo) . '.' . $name . '.' . $ext;
