How can the use of true and false in stripos comparisons be optimized in PHP code?

When using stripos in PHP for case-insensitive string comparisons, it's important to use true and false strictly in the comparison to avoid unexpected results. To optimize this, always use strict comparison operators (===) when checking the result of stripos to ensure the correct boolean value is returned.

// Incorrect comparison without strict comparison operator
if (stripos($haystack, $needle)) {
    // This block will execute even if the needle is not found
}

// Correct comparison using strict comparison operator
if (stripos($haystack, $needle) !== false) {
    // This block will only execute if the needle is found
}
