Conditional logic in PHP, including if statements, switch statements, and logical operators like if-else, and, and or, allows you to control the flow of your code based on specific conditions. By mastering these concepts, you can create more dynamic and flexible PHP applications.
If Statements
If statements allow you to execute certain blocks of code conditionally based on whether a specified condition evaluates to true or false.
$age = 25;
if ($age < 18) { echo "You are a minor."; } elseif ($age >= 18 && $age < 65) { echo "You are an adult."; } else { echo "You are a senior citizen."; }
Switch Statements
Switch statements provide an alternative way to evaluate multiple conditions against a single value.
