<h1>PHP Version Support 
 </h1>
<p>PDT supports 
 PHP versions 4, 5.1/5.2 and 5.3.</p>
<p>&#160;</p>
<p>PHP version settings affect:</p>
<ul type="square">
	<li><p>The elements displayed in the <a href="php_functions_view.htm">PHP 
	 Functions view</a>.</p></li>
	<li><p>The options available in <a href="code_assist_concept.htm">Content 
	 Assist</a>.</p></li>
	<li><p>Debugging 
	 functionality.</p></li>
</ul>
<p>&#160;</p>
<p>PHP version settings can be configured from the following places:</p>
<ul type="square">
	<li><p>PHP Executables can be added and edited from the <a href="php_executables.htm">PHP 
	 Executables Preferences</a> page.</p></li>
	<li><p>The default PHP executable used for new projects can be set 
	 in the <a href="php_interpreter.htm">PHP Interpreter Preferences</a> 
	 page. Through this page you can also set the PHP version for specific 
	 projects.<br>
	In addition, you can select which PHP Version should be used when creating 
	 a new PHP project by marking the Enable Project Settings checkbox 
	 in the New PHP Project dialog.</p></li>
</ul>
