How can older templates be successfully installed on newer versions of Joomla using PHP?

When attempting to install older templates on newer versions of Joomla, compatibility issues may arise due to changes in the Joomla framework. To successfully install older templates, you can modify the templateDetails.xml file to specify the supported Joomla versions. This can be done by updating the <install> tag with the minimum and maximum supported Joomla versions. 

$xml = simplexml_load_file(&#039;templateDetails.xml&#039;);
$xml-&gt;extension[0]-&gt;install[0]-&gt;attributes()-&gt;version = &#039;3.0.0&#039;;
$xml-&gt;extension[0]-&gt;install[0]-&gt;attributes()-&gt;client = &#039;site&#039;;
$xml-&gt;asXML(&#039;templateDetails.xml&#039;);
