 ====== Configuring cPanel EA4 + CloudLinux + LSWS to Use CloudLinux PHP Selector Instead of EA4 MultiPHP ======
-If you use cPanel EA4 on a CloudLinux system, the LiteSpeed auto-installer script will add the proper external apps for both EA4 MultiPHP and CloudLinux PHP Selector automatically, when installing LSWS.  PHP handlers will be set to use EA4 MultiPHP by default with version 5.6.
+If you use cPanel EA4 on a CloudLinux system, the LiteSpeed(LSWS < 5.4) auto-installer script will add the proper external apps for both EA4 MultiPHP and CloudLinux PHP Selector automatically, when installing LSWS.  PHP handlers will be set to use EA4 MultiPHP by default with version 5.6.
+However, there is an important change starting from LSWS 5.4,  external apps and script handlers are not necessary unless you want to specifily define handlers. External apps may still exist/be inherited if you upgrade LSWS from an earlier version but you may find the external app and script handler empty for the new installation.
+The followings are explained how an earlier version of LSWS(<5.4) exnternal apps and script handler work or inherited external apps and script handlers for LSWS 5.4 and above.
 The following external apps are installed:

-**It will be supported from 5.3RC1**
+**As of LSWS v5.3RC1, you can use alt-php directly from MultiPHP Manager**
+In cPanel & WHM version 66 and later, EasyApache 4 allows you to use Vendor-provided PHP versions such as CloudLinux PHP selector right from MultiPHP Manager. This includes ''alt-php44'', ''alt-php51'', ''alt-php52'', ''alt-php53'', ''alt-hpp54'', ''alt-php55'', ''alt-php56'', ''alt-php70'', ''alt-php71'', ''alt-php72''. The ''alt-php''s are supported by LiteSpeed from 5.3RC1.

If your version under it, please continue to use ''ea-phpxx'' and follow the above steps to determine if CloudLinux PHP selector is used,  but not directly from MultiPHP Manager.
+LSWS versions 5.2.x and below //do not// support ''alt-php'', so if you are still using such a legacy version, please continue to use ''ea-phpxx'' only. Skip this section, and follow the above steps to determine if CloudLinux PHP selector is used. Do not use MultiPHP Manager.
+Using cPanel MultiPHP Manager is the recommended method, since it is easy to understand and supports both ''ea-php'' and ''alt-php''.  CloudLinux PHP selector sometimes might be a little complicated to understand, hence it is not recommended. An advanced user can choose either one as preferred, as long as it is understood how CloudLinux PHP selector works together with WHM/cPanel MultiPHP Manager. The following section **Why CloudLinux PHP Selector Works on Apache but Does Not Work on LSWS** provides a good example of how complicated it can be to try enforcing everything to ''alt-php'' while using CloudLinux PHP Selector. Unless you understand it well, we don't recommend you go through such a complicated path for such little benefit. MultiPHP Manager could simply make your life easier.

+===== Why CloudLinux PHP Selector Works on Apache but Does Not Work on LSWS =====
+In a cPanel EA4 and CloudLinux environment, Most of the LSWS LSPHP external apps such as ''lsphpxx'' are pointing to ''ea-phpxx'', instead of ''alt-phpxx''. Only one external app, ''cl_phpselector'' is pointing to ''/usr/local/bin/lsphp'' (the CloudLinux PHP selector binary).
+  lsphp54-> /opt/cpanel/ea-php54/root/usr/bin/lsphp
+  lsphp55-> /opt/cpanel/ea-php55/root/usr/bin/lsphp
+  lsphp56-> /opt/cpanel/ea-php56/root/usr/bin/lsphp
+  lsphp70-> /opt/cpanel/ea-php70/root/usr/bin/lsphp
+  lsphp71-> /opt/cpanel/ea-php71/root/usr/bin/lsphp
+  lsphp72-> /opt/cpanel/ea-php72/root/usr/bin/lsphp
+  cl_phpselector-> /usr/local/bin/lsphp
+PHP handlers:
+  php  -> cl_phpselector
+  php5 -> cl_phpselector
+  php54-> lsphp54
+  php55-> lsphp55
+  php56-> lsphp56
+  php70-> lsphp70
+  php71-> lsphp71
+  php72-> lsphp72
+The above is the recommended way, and is the default setup for such an environment.
+{{ :litespeed_wiki:cpanel:cpanel-ea4-cloudlinux-apache-lsws-different-php.png?800 |}}
+Some users may want to point every external handler to ''alt-phpxx'', like so:
+  lsphp54-> /opt/alt/php54/usr/bin/lsphp
+  lsphp55-> /opt/alt/php55/usr/bin/lsphp
+  lsphp56-> /opt/alt/php56/usr/bin/lsphp
+  lsphp70-> /opt/alt/php70/usr/bin/lsphp
+  lsphp71-> /opt/alt/php71/usr/bin/lsphp
+  lsphp72-> /opt/alt/php72/usr/bin/lsphp
+  cl_phpselector->/usr/local/bin/lsphp
+This causes a problem.
+For example: A user account inherits the cPanel system default PHP version, and the CloudLinux PHP selector is set to use ''php70'' for that user account. Apache seems to return the correct version of ''php70'', but LSWS always seems to return ''php56'' (or whatver cPanel's Multi PHP Manager system default PHP version is).
+In actuality, there is nothing wrong with LiteSpeed Web Server. LSWS is following the correct CloudLinux-cPanel-EA4 PHP determination work flow.
+  * **Apache**: When a user account inherits the cPanel system default PHP configuration from cPanel Multi PHP Manager, the CloudLinux PHP Selector is used. Hence it returns the right PHP version.
+  * **LSWS**: Since you changed the external app associated with the cPanel default version (''ea-php56'' in this example), it will look for the suffix ''php56'', which points to ''lsphp56''.
+''lsphp56'' was:
+  lsphp56-> /opt/cpanel/ea-php56/root/usr/bin/lsphp
+You changed it to:
+  lsphp56-> /opt/alt/php56/usr/bin/lsphp
+''/opt/alt/php56/usr/bin/lsphp'' is differnt than cPanel's default ''ea-php56''(which is  ''/opt/cpanel/ea-php56/root/usr/bin/lsphp''), hence the CloudLinux PHP Selector won't be used. Instead, ''lsphp56'' (or, ''/opt/alt/php56/usr/bin/lsphp'') will be always used for LSWS.
+So, how can you get the PHP version you want? The key is to tell LSWS to use the CloudLinux PHP selector instead of a particular version of alt-php.
+You can either update the external app ''lsphp56'' to point to PHP selector binary ''/usr/local/bin/lsphp'', or more easily, update the PHP handler of suffix ''php56'' to be served by ''cl_phpselector'' instead of ''lsphp56''.
+You can apply the second solution through the command line or through LSWS Web Admin Console.
+==== Through the Command Line ====
+  vi /usr/local/lsws/conf/httpd_config.xml
+Change:
+    <scriptHandler>
+      <suffix>php56</suffix>
+      <type>lsapi</type>
+      <handler>lsphp56</handler>
+    </scriptHandler>
+To:
+    <scriptHandler>
+      <suffix>php56</suffix>
+      <type>lsapi</type>
+      <handler>cl_phpselector</handler>
+    </scriptHandler>
+==== Through LSWS Web Admin Console ====
