No, sory, my bad typing. It's not the problem..
I have the same on both caxses, only chnage the variable $id
$file = "screen/temp/7a45gfdi6icpan1jtb1j99o925_1_mini.jpg"
$id = '70';
echo preg_replace('#(screen/)temp/(.+?)_1(.+?\.jpg)#', '$1'.$id, $file);
Get: 0
file = "screen/temp/7a45gfdi6icpan1jtb1j99o925_1_mini.jpg";
$id = test;
echo preg_replace('#(screen/)temp/(.+?)_1(.+?\.jpg)#', '$1'.$id, $file);
Get: screen/test
What is wrong with having na integer on the var ?
Thank you

You have a great big capital I in there... Try removing that and see
what happens.
