Bug description: strripos issues unepxected warning with UNICODE haystack
Description:
------------
I get an unexpected warning msg when I specify an haystack with a non-zero
offset.
I think the problem lies in the following code in ext/standard/string.c
2913 if (haystack_type == IS_UNICODE) {
2914 if (offset >= 0) {
2915 U16_FWD_N(haystack.u, cu_offset, haystack_len, offset);
2916 if (cu_offset > haystack_len - needle_len) {
2917 php_error_docref(NULL TSRMLS_CC, E_NOTICE, "Offset is greater
than the length of haystack string");
2918 RETURN_FALSE;
2919 }
2920 u_p = haystack.u + cu_offset;
2921 u_e = haystack.u + haystack_len - needle_len;
2922 } else {
If (cu_offset > haystack_len - needle_len) then FALSE should be returned
but the warning is bogus; that should only be output if cu_offset >
haystack_len.
Reproduce code:
---------------
<?php
$haystack = "abcdefg";
$needle = "abcdefg";
var_dump( strripos($haystack, $needle, 0) );
var_dump( strripos($haystack, $needle, 1) );
?>
Expected result:
----------------
int(0)
bool(false)
Actual result:
--------------
int(0)
bool(false)
PHP Notice: strripos(): Offset is greater than the length of haystack
string in .... etc
