PHP simple if statement

Labels
if statement in php is similar to almost all languages, and it necessary to make a usefull script.

If statement enable you to execute a script only if a condition is true.

Simple if statement:

php code:
<?php
$age = 28;

 if ($age == 28)
 echo "hello ! Your age is 28";
 ?>
Display:
hello ! Your age is 28

But if you want to do many lines of code under the if statement, you should do:

php code:
<?php
$age = 28;

 if ($age == 28)
{
 echo "hello ! Your age is 28";
echo "
" ;
 echo "You are wellcome !";
?>
Display:
hello ! Your age is 28
You are wellcome !
