PHP if Statements

PHP Conditional Statements

Conditional statements are used to perform different actions based on different conditions.

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

PHP - The if Statement

The if statement executes some code only if the specified condition is true.

Syntax

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

if (5 > 3) {
  echo "Have a good day!";
}

It is common to use variables in the if statement:

$t = 14;
if ($t < 20) {
  echo "Have a good day!";
}
