The Optional Else Command in PHP
The else construct is not mandatory.
In the following example, the text will be displayed only if
the variable value is equal to 1.
Otherwise, nothing will happen:
<?php
$test = 1;
if ($test == 1) {
echo '+++';
}
?>
If the variable $test is equal to 10,
then '+++' should be displayed on the screen.
Otherwise, nothing should happen.
