What are the potential pitfalls of using logical operators like !== in PHP comparisons, and how can they be avoided?

Using !== in PHP comparisons can lead to unexpected results if the data types being compared are not the same. To avoid this pitfall, it's important to ensure that the data types are consistent before using !==. One way to do this is by using typecasting to explicitly convert variables to the same data type before performing the comparison.

// Example of using typecasting to avoid pitfalls with !==
$var1 = "10";
$var2 = 10;

if ((int)$var1 !== (int)$var2) {
    echo "Variables are not equal";
} else {
    echo "Variables are equal";
}
