Change the name of your inputs like this:

<form action = "put the data to a single PHP array" method="post">
    <input name="a[]" type="text" />
    <input name="a[]" type="text" />
    <input name="a[]" type="text" /> 
    <input name="a[]" type="text" /> 
    <input type="button"/>
</form>

You can then retrieve the array as follows:

$values = $_POST['a'];
