Conditionals and Control Flow 2/4
If statements
Nice work on comparisons! Now let's see how we can use comparisons to ask yes or no questions.
Say we want to write a program that asks whether your name is longer than 7 letters. If the answer is yes, we can respond with "You have a long name!" We can do this with an
ifstatement:<?php
$age = 17;
if( $age > 16 ) {
echo "You can drive!";
}
?>
An if statement is made up of the
ifkeyword, a condition like we've seen before, and a pair of curly braces { }. If the answer to the condition is yes, the code inside the curly braces will run.
