Strrchr issue using capitalised characters 1

[monkey64]

The strrchr() function finds the position of the last occurrence of a string within another string, and returns all characters from this position to the end of the string.

My code:

echo strrchr("I am searching for OBSVALUE on my text", "OBSVALUE") . "<br>";
echo strrchr("I am searching for OBSVALUE ON my text", "OBSVALUE");

In the first example, I get "OBSVALUE on my text" and that's what I would expect.
In the second, I get "ON my text". I was expecting the same.

Any ideas why there is a variation?

the function does not behave as you would expect. note the sentence in the manual

If needle contains more than one character, only the first is used. This behavior is different from that of strstr().

if you want to get the remains of a string try this instead

<?php
function getEndBit($haystack, $needle, $caseInsensitive=false){
	if ($caseInsensitive){
		$haystack = strtolower($haystack);
		$needle = strtolower($needle);
	}
	$bits = explode($needle, $haystack);
	if (count ($bits) == 0) return false;
	return $needle . end($bits);
}

echo getEndBit("I am searching for OBSVALUE on my text", "OBSVALUE") . "<br>";
echo getEndBit("I am searching for OBSVALUE ON my text", "OBSVALUE");
?>

OBSVALUE on my text
OBSVALUE ON my text

Fantastic jpadie!
Well I never knew that! My book doesn't really go into details. Your code is good.

Thanks again
