select only text input names from POST

[codenet]

I want to echo the names of the text inputs, but this also echos the submit input name, how can I change it so that it ony selects inputs with type="text" in them?\[code\]<?php if(isset($_POST['submit'])){ foreach( $_POST as $value){ echo $value; } }?> <form action="ajax.html" method="POST"> <input type="text" name="a"> <input type="text" name="b"> <input type="text" name="c"> <input type="submit" name="submit"> </form>\[/code\]
