strripos
Find position of last occurrence of a case-insensitive string in a string
(PHP 5)
int strripos ( string haystack, string needle [, int offset] )
Find position of last occurrence of a case-insensitive string in a string. Unlike strrpos(), strripos() is case-insensitive.
Parameters
- haystack
- needle
Note that the needle may be a string of one or more characters.
- offset
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.
Return Values
Returns the numerical position of the last occurence of needle. Also note that string positions start at 0, and not 1.
If needle is not found, FALSE is returned.
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.
Examples
Example 2464. A simple strripos() example
<?php
$haystack = 'ababcd';
$needle = 'aB';
$pos = strripos($haystack, $needle);
if ($pos === false) {
echo "Sorry, we did not find ($needle) in ($haystack)";
} else {
echo "Congratulations!\n";
echo "We found the last ($needle) in ($haystack) at position ($pos)";
}
?>The above example will output:
Congratulations!
We found the last (aB) in (ababcd) at position (2)
