PHP if…else

PHP – The if…else Statement

The if…else statement runs a specific block of code if a condition is true and a different block if the condition is false.

Syntax

if  (condition) {
// code to be executed if condition is true;
} else {
// code to be executed if condition is false;
}

Example

Output “Have a good day!” if the current time is before 20:00, and “Have a good night!” if it’s 20:00 or later.

$t = date("H");
if ($t < "20") {
 echo "Have a good day!";
} else {
 echo "Have a good night!";
}

 

PHP – The if…elseif…else Statement

The if…elseif…else statement runs different blocks of code for multiple conditions.

 

Syntax

if (condition) {
code to be executed if this condition is true;
} elseif (condition) {
// code to be executed if first condition is false and this condition is true;
} else {
// code to be executed if all conditions are false;
}

Example

Output “Have a good morning!” if the current time is before 10:00, “Have a good day!” if it’s before 20:00, and “Have a good night!” otherwise.

$t = date("H");
if ($t < "10") {
 echo "Have a good morning!";
} elseif ($t < "20") {
 echo "Have a good day!";
} else {
 echo "Have a good night!";
}
