What are the potential pitfalls of using typeschwachen Stringvergleichen in PHP?

Using type-weak string comparisons in PHP can lead to unexpected results due to PHP's loose typing system. To avoid this, always use strict type comparisons (===) when comparing strings to ensure both the value and type match.

// Incorrect way using type-weak string comparison
if ($string1 == $string2) {
    echo "Strings are equal";
}

// Correct way using strict type comparison
if ($string1 === $string2) {
    echo "Strings are equal";
}
