Multiple $_POST on same page PHP

I have a question.

Currently this form will be dynamically generated.

Example,

<form method="POST">
<input type="text" name="location" id="location1" />
<input type="submit" value="Submit!" />

<input type="text" name="location" id="location2" />
<input type="submit" value="Submit!" />

<input type="text" name="location" id="location3" />
<input type="submit" value="Submit!" />

<input type="text" name="location" id="location4" />
<input type="submit" value="Submit!" />
</form>

So whenever i press submit, it will take last value of form only. How do i make it take all $_POST?

Thank you.

Answer

Give each input its own name or use:

<input type="text" name="location[]" id="location1" />

Then PHP will treat it like an array.
