How does PHP handle type comparison with == and === operators?

When comparing types in PHP, the == operator performs a loose comparison, allowing for type coercion. This means that values of different types may be considered equal if their values are equivalent after type conversion. On the other hand, the === operator performs a strict comparison, checking both the values and the types of the operands. To avoid unexpected results, it is generally recommended to use the === operator for type-safe comparisons.

$value1 = 5;
$value2 = "5";

// Loose comparison
if ($value1 == $value2) {
    echo "Loose comparison: Equal";
} else {
    echo "Loose comparison: Not equal";
}

// Strict comparison
if ($value1 === $value2) {
    echo "Strict comparison: Equal";
} else {
    echo "Strict comparison: Not equal";
}
