After click <li> include PHP file to DIV.

[Smashden]

Hello, I have a script in JS which makes that when you click on <li> shows include PHP in DIV(load after the page loads). I want to include PHP file when I click  and show it. How can I do it in AJAX? Look at me code:

					<ul class="task-menu" style="width: 200px;">			
						<li class="account_buttons" data-target=".option1">Create Character</li>
						<li class="account_buttons" data-target=".option2">Delete Character</li>
						<li class="account_buttons" data-target=".option3">Change Password</li>
						<li class="account_buttons" data-target=".option4">Change Email</li>
						<li class="account_buttons" data-target=".option5">Create Guild</li>					
					</ul>
					<script>
						$(document).ready(function () {
							var $targets = $('.target');
							$('.task-menu .account_buttons').click(function () {
								var $target = $($(this).data('target')).toggle(600);								
								$targets.not($target).hide(800)
							});					
						});
					</script>	

This I have on botttom my page:

		<div class="option1 target" style="display: none;">
			<hr class="account_edit">
			<?php include ("modules/option1.php"); ?> -- here I want to include when I click on option1
			<script src="javascript/option1_script.js"></script>
		</div>
		<div class="option2 target" style="display: none;">
			<hr class="account_edit">
			<?php include ("modules/option2.php"); ?> -- here I want to include when I click on option2
			<script src="javascript/option2_script.js"></script>	
		</div>
		<div class="option3 target" style="display: none;">
			<hr class="account_edit">
			<?php include ("modules/option3.php"); ?> -- here I want to include when I click on option2
			<script src="javascript/option3_script.js"></script>	
		</div>
		<div class="option4 target" style="display: none;">
			<hr class="account_edit">
			<?php include ("modules/option4.php"); ?> -- here I want to include when I click on option2
			<script src="javascript/option4_script.js"></script>
