What are the potential pitfalls of using "!=" as a comparison operator in PHP?

Using "!=" as a comparison operator in PHP can lead to unexpected results due to type coercion. It may not accurately compare values of different types, leading to errors in conditional statements. To avoid this issue, it's recommended to use the "!==", which compares both value and type. 

// Using "!=="" to accurately compare both value and type
if ($variable !== 10) {
    echo "Variable is not equal to 10";
}
