The if...else statement executes one block of code if a condition is true and another block if the condition is false.
Syntax
if (condition) {
// Code executed if the condition is true
} else {
// Code executed if the condition is false
}Example
Here’s an example based on motorcycles. If you own fewer than 5 motorcycles, it suggests buying a Yamaha; otherwise, it suggests riding a Honda:
$motorcycleCount = 3; // Change this number to test different outputs
if ($motorcycleCount < 5) {
echo "Why not add a Yamaha to your collection?";
} else {
echo "Take your Honda for a spin!";
}PHP – The if…elseif…else Statement
The if...elseif...else statement allows you to evaluate multiple conditions and execute different blocks of code accordingly.
Syntax
if (condition) {
// Code executed if this condition is true
} elseif (condition) {
// Code executed if the first condition is false and this one is true
} else {
// Code executed if all conditions are false
}Example
Consider this example based on cars. If someone has fewer than 2 cars, it suggests a Tesla; if they own between 2 and 5, it suggests a Toyota; otherwise, it recommends driving a BMW:
$carCount = 4; // Change this number to test different outputs
if ($carCount < 2) {
echo "Maybe consider buying a Tesla.";
} elseif ($carCount <= 5) {
echo "How about getting a reliable Toyota?";
} else {
echo "Enjoy your luxurious BMW!";
