Returns the numeric position of the last occurrence of
needle
in the
haystack
string. Unlike
strrpos(), strripos() is
case-insensitive. Also note that string positions start at 0, and not
1.
Note that the needle
may be a string of one or
more characters.
If needle
is not found, FALSE is returned.
Warning |
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. |
The offset
parameter may be specified to begin
searching an arbitrary number of characters into the string.
Negative offset values will start the search at
offset
characters from the
start of the string.
