PHP If Else

Very often when you write code, you want to perform different actions for different conditions. You can use conditional statements in your code to do this.

In PHP we have the following conditional statements:

• if statement - executes some code if one condition is true
• if...else statement - executes some code if a condition is true and another code if that condition is false
• if...elseif...else statement - executes different codes for more than two conditions
• switch statement - selects one of many blocks of code to be executed

The if statement executes some code if one condition is true. Syntax :

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

For Example :

<?php
$t = date("H");

if ($t < "20") {
  echo "Have a good day!";
}
?>

The if...else statement executes some code if a condition is true and another code if that condition is false.

<?php
$t = date("H");

if ($t < "20") {
  echo "Have a good day!";
} else {
  echo "Have a good night!";
}
?>

PHP - The if...elseif...else Statement

Output "Have a good morning!" if the current time is less than 10, and "Have a good day!" if the current time is less than 20. Otherwise it will output "Have a good night!":

<?php
    $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!";
    }
?>

Now that you have done if-else statements in Php, let's learn for loop in php
