What is the significance of using the logical operators && and || in PHP if statements?

The logical operators && and || are used in PHP if statements to combine multiple conditions together. The && operator represents logical AND, meaning that all conditions must be true for the overall condition to be true. The || operator represents logical OR, meaning that at least one condition must be true for the overall condition to be true. By using these operators, you can create more complex conditional statements that can accurately evaluate multiple conditions.

// Example of using logical operators in PHP if statements
$age = 25;
$isStudent = true;

if ($age >= 18 && $isStudent) {
    echo "You are a student over 18 years old.";
} elseif ($age >= 18 || $isStudent) {
    echo "You are either a student or over 18 years old.";
} else {
    echo "You are neither a student nor over 18 years old.";
}
