Re: Can $_POST variables be modified in a function?

Hello Erwin,

It's a little bit different. I'm trying to modify the $_POST variables
inside a function. When I modify $_POST inline like you show, it works
just fine. It's when it's within a function that the outcome is
screwy. My example would look like this:

<?php

function modifyPost() {
$_POST['var1'] = 'foo';
}
?>

Post before:
<br>
<pre>
<?php print_r($_POST); ?> //Prints [var1] = foo
</pre>

<?php
modifyPost();
?>
<hr>
after:
<br>
<pre>
<?php print_r($_POST); ?> // Prints [var1] = ''
</pre>
.
