Echo an $_POST in PHP

Question

How can I print a $_POST?

Example:

echo $_POST['data'];

This returns nothing...

Answer 1

You can also wrap your code with <pre> tags to make your array prints out nicer instead of just 1 continuous line. A trick that was shown by a member on this site.

<pre>
<?php var_dump($_POST); ?>
</pre>

Answer 2

Your code is correct.

You can use either:

var_dump($_POST);

or

print_r($_POST);

to print out the entire POST array for debugging.

Answer 3

You can only show the values of keys that exist. array_keys() returns an array containing the keys that exist in the array. If there is no output for a key despite the fact that the key exists then the array may contain an empty value for that key.
