Comparison of variables

What comparison function?

[bethesda]

Hello again.
I want to compare the variable and its contents.
I wanted to ask you which function is best to use ?

if(stristr($var, 'my_string_to_compare') === TRUE) {
header("Location: ../scriptA.php?allok");
} else {
header("Location: ../scriptB.php?error");
exit();
}

I guess I chose the wrong function.
Generally, I am looking for a function that will check the contents (caseSensitive).

Then, if the contents match - redirect on page X, or if the contents do not agree, you are directed to Y.

In this case, even when the variable contains a valid string of characters - you are redirected to a page with an error.

Are you sure? This function should not be used for string comparison since it is slower than the alternatives.

Unless you are wanting to check for a partial match, what is wrong with a simple equality comparison...

if ($var == 'my_string_to_compare') {

Or, if you need a partial match where 'my_string_to_compare' should be anywhere inside $var then use strpos() [uk.php.net]...

if (strpos($var,'my_string_to_compare') !== false) {

Thanks. I switch it to

strpos

I wish you all a healthy and peaceful Christmas and all the best in the coming new year.

I would prefer switch [php.net], if there are lots of IFs.
