I have a preg_replace function that replaces the first match of NUMBERxNUMBER in a sring. I need it to replace only the last match and i can't figure it out.

preg_replace("#-\d+x\d+#", "",  $string, 1)

I tried putting a $ before the # but doesn't work...

Thank you.

Before the *last* `#`? It should work. See https://regex101.com/r/eBqUaW/1 – Wiktor Stribiżew Nov 23 '16 at 14:55
Or does that value appear not at the end of the string? You mean there can be some text other than `-\d+x\d+` after the last pattern occurrence? – Wiktor Stribiżew Nov 23 '16 at 14:59
