iconv_strrpos
Finds the last occurrence of a needle within a haystack
(PHP 5)
int iconv_strrpos ( string haystack, string needle [, string charset] )
In contrast to strpos(), the return value of iconv_strrpos() is the number of characters that appear before the needle, rather than the offset in bytes to the position where the needle has been found.
Parameters
- haystack
The entire string.
- needle
The searched substring.
- charset
If charset parameter is omitted, string are assumed to be encoded in iconv.internal_encoding.
If haystack or needle is not a string, it is converted to a string and applied as the ordinal value of a character.
Return Values
Returns the numeric position of the last occurrence of needle in haystack. The characters are counted on the basis of the specified character set charset.
If needle is not found,
iconv_strrpos() will return FALSE.
This function may
return Boolean FALSE, but may also return a non-Boolean value which
evaluates to FALSE, such as 0 or
"". Please read the section on Booleans for more
information. Use the ===
operator for testing the return value of this
function.
