Check textarea with php

I have a textarea field and want to add a text or php code when the field is empty and if the field is not empty to add another php code. For example:

if the field is empty>do something.....else>do something...

I'm not good at php, so I'll be glad for any help. Thanks.

p.s.Sorry for my english.

To test if outside variable is empty or not, you can just compare it with empty string

if ( $_POST['text'] === '') {
     echo 'there was something';
} else {
     echo 'nothing to say';
}

Assuming you're posting this from a form then you can do the following.

I'll write this out the long way so it's easier to understand:

if (!empty($_POST['TEXTAREA_NAME']){
     // If the textarea is set then do something here
} else {
     // If it is NOT set it then it will do the code here
}

<?php echo isset($_POST['texarea_name']) && !empty($_POST['texarea_name']) ? 'textarea not empty' : 'texarea is empty'; ?>
