What is the correct comparison operator in PHP for equality?

In PHP, the correct comparison operator for equality is ==. This operator checks if two values are equal, regardless of their data types. It is important to use == for equality comparisons, as using = will result in assignment instead of comparison.

// Example of using the correct comparison operator for equality
$var1 = 5;
$var2 = "5";

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