Making my own STRPOS function.

[748323]

Honestly, I hate PHP's STRPOS. I never seem to remember how to use it, unless I look it up on php.net. I decided to make my own function to check if one string is present in another. Other than slower loading times, is there anything bad about using my custom function? Thanks.

<?

function aisinb($string, $string2) {
	$string2_copy = $string2;
	$string2_copy = str_replace($string, "", $string2_copy);
	if ($string2 != $string2_copy) {
		return TRUE;
	} else {
		return FALSE;
	}
}

?>

Correct me if I'm mistaken, but does your function not only return TRUE or FALSE?

strPOS, returns the POSition of the STRing.

I know, but STRPOS will return true if one string appears in another. That's what I'm trying to duplicate.

Returns the numeric position of the first occurrence of needle in the haystack string. Unlike the strrpos(), this function can take a full string as the needle parameter and the entire string will be used.

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.

I dont think you quite get what you use the strpos function for.

Have you considered using stristr() instead?
