This question already has an answer here:
I've read many threads here about this being deprecated and tried replacing it with preg_match but I don't know php enough to fix the rest of the line.
Been enjoying Fotoholder for years, I would switch to a newer similar single file gallery code but then I would lose all my descriptions in the gallery.
Please help resurrect Fotopholder! ( https://github.com/offsky/Fotopholder )
Here are the 2 parts that have eregi:
if(substr($entry,0,1)!="." && !preg_match("#_cache#i",$entry) && is_dir($path."/".$entry)) {
and the 2nd eregi:
if(substr($entry,0,1)!="." && !eregi("_cache",$entry)) {Thank you very much for your help.
</div>
Deprecated means, that the function eregi() is likely to get deleted from the language.
Please use preg_match().
While you still can use eregi(), at a certain point of time your application might not be able to execute any more.
That said: Your code posted is far to big to get a detailed answer.
