I want to compare variables strings just like you do in mysql except in a if statement. I know this wont work but a perfect example would be.

PHP Code:

if($var == %info%) { echo 'this works'; }
//if the variable contains the words info in it echo this works.

Thanks I'm going to also look up regular expression, hopefully it helps.

http://php.net/manual/en/function.strcmp.php

using strpos will tell you the position of the word your looking for.

If it returns a position, You know it exists ( you dont care about the position )
But the fact that its found one, tells you that its found the word.

Using strpos:

PHP Code:

<?php

$hayStack = "The needle lies in the haystack";

if (strpos($hayStack, "needle")) {
    echo "Word exists in that string!";
} else {
    echo "Word doesn't exist in that string.";
}
    
?>

Daily I am looking the expression now a day.

Perfect for comparing strings

I believe the OP is trying to determine if an input string contains a substring. strcmp compares strings lexicographically.
