Answer 1

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'];

hi Jonas if you need the values to be passed as an array then you can use

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

while accessing you can use

$ar=$_POST['ar'];
$size=sizeof($ar);
    for($i=0;$i<$size;$i++)
    {
      echo "$ar[$i]";
    }

Generally we use this type of array passing when we use multiple checkboxes value to be passed
