PHP If Statement
You can use the PHP If statement to execute code based on condition(s). This statement is also called a conditional statement or the conditional structure. You can make decisions and execute code only when the conditions are met.
Syntax
Let’s look at the simple syntax of the statement.
if(condition)
{
// PHP Statements;
}
The PHP code in the if block will be executed when the condition is met, i.e., evaluates to true.
Example
Simple if statement example:
<?php
// PHP conditional statement
if ($age>=18) {
echo " Adult.";
} else {
echo "Minor.";
