try searching for this on google..! pft!
Anyway -
what does .= mean? (.=) it's the short way of writing something, but can someone explain slowly, in small words?
Eg, I've got this line in a tutorial:
$result_final .= 'File ' . ($counter + 1) . ' is not a photo<br />';
but it works just the same if I remove that dot before the (=) sign, so it's:
$result_final = 'File ' . ($counter + 1) . ' is not a photo<br />';
spooky!
