PHP If else

In PHP, the if-else statement is used to execute different blocks of code based on a condition. The if block contains the code that will be executed if the condition evaluates to true, and the else block contains the code that will be executed if the condition evaluates to false.

Here’s the syntax of the if-else statement:

if (condition) {
    // Code to be executed if the condition is true
} else {
    // Code to be executed if the condition is false
}

Example of the if-else statement:

$age = 25;

if ($age >= 18) {
    echo "You are an adult.";
} else {
    echo "You are a minor.";
}

In this example, we have a variable $age with a value of 25. The if-else statement checks whether the value of $age is greater than or equal to 18. If the condition is true (which it is in this case), the code inside the if block will be executed, and it will output “You are an adult.” If the condition is false, the code inside the else block will be executed, and it will output “You are a minor.”

Additionally, you can use the elseif keyword to add more conditions to the if-else statement:

$score = 75;

if ($score >= 90) {
    echo "Excellent!";
} elseif ($score >= 80) {
    echo "Very good!";
} elseif ($score >= 70) {
    echo "Good!";
} else {
    echo "Keep practicing!";
}

In this example, the elseif keyword is used to add additional conditions to the if-else statement. The code will check the value of $score and print different messages based on the score range.

The if-else statement allows you to control the flow of your PHP code based on specific conditions, making your code more flexible and responsive to different situations.
