+s64 strpos(String haystack, String needle, s64 offset = 0)
+
+:params
+haystack : string to search in
+needle : substring to search for
+offset : optional start offset; negative values count from the end of the string
+return value : zero-based position of the first match, or `-1` if `needle` is not found
+
+:desc
+Finds the first occurrence of `needle` inside `haystack`.
+
+This is the closest UCE equivalent to PHP `strpos()`, but it returns `-1` instead of `false` when no match is found.
+
+If `needle` is an empty string, `strpos()` returns the normalized start offset.
