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

|
|
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.
