The If statement

The syntax of If statement is:

if (conditions) {
//do something
}else{
//do other thing
}

For example:

<?php
if($name == "zhou") {
echo "Welcome $name!";
} else {
echo "Sorry, you are not authorized 
	to access this page.";
}
?>

You can use "if ...elseif ... else" to add more condition statements.

There are many different comparison operators that are the foundation for building our conditionals, and they are listed below:
