strripos Find the position of the last occurrence of a case-insensitive substring in a string &reftitle.description; intstrripos stringhaystack mixedneedle intoffset0 Find the numeric position of the last occurrence of needle in the haystack string. Unlike the strrpos, strripos is case-insensitive. &reftitle.parameters; haystack The string to search in. needle &strings.parameter.needle.non-string; offset If zero or positive, the search is performed left to right skipping the first offset bytes of the haystack. If negative, the search is performed right to left skipping the last offset bytes of the haystack and searching for the first occurrence of needle. This is effectively looking for the last occurrence of needle before the last offset bytes. &reftitle.returnvalues; Returns the position where the needle exists relative to the beginnning of the haystack string (independent of search direction or offset). String positions start at 0, and not 1. Returns &false; if the needle was not found. &return.falseproblem; &reftitle.examples; ]]> &example.outputs; &reftitle.seealso; strpos stripos strrpos strrchr stristr substr
