Remove submit button value from $_POST form data PHP

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?

<?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>

POST doesn’t know how the data was gathered. The only way you could do this is like so:

<?php
if (isset($_POST['submit']))
{
    foreach ($_POST as $key => $value)
    {
        if ($key != 'submit')
        {
            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>
