How can PHP beginners avoid common pitfalls when differentiating between two options in their code?

Beginners can avoid common pitfalls when differentiating between two options in their code by using strict comparison operators (=== and !==) instead of loose comparison operators (== and !=). Strict comparison operators not only compare the values of variables, but also their types, ensuring a more accurate comparison. 

// Incorrect comparison using loose comparison operator
$var1 = 5;
$var2 = '5';

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

// Correct comparison using strict comparison operator
$var1 = 5;
$var2 = '5';

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