-**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).
-===== Why CloudLinux PHP selector works on Apache but does not work on LSWS? =====
-At cPanel EA4 and CloudLinux environment, Most of the LSWS LSPHP external apps such as lsphpxx are poiting to ea-phpxx, instead of
-alt-phpxx. Only one external app "cl_phpselector" is poiting to "/usr/local/bin/lsphp" (CloudLinux PHP selector binary).

- Which causes a problem: when a user account inherited cpanel system default PHP version and CloudLinux PHP selector is set to use php70 for that user account, Why apache seems returning the right version of php70 but LSWS seems always returning php56  or other php version alighing with cpanel multi-php manager system default php version?
+This causes a problem.
-Actually there is nothing wrong with LSWS, LSWS is still follow CloudLinux-cPanel-EA4 php determination work flow.
+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).
-When a user account inherited cpanel system default PHP configurated from cPanel Multi PHP Manager, on Apache, CloudLinux PHP Selector is used hence it returns right php version.  On LSWS, since you change the external app associated with cpanel default version ea-php56 in this example. It will look for suffix php56, which is currently using lsphp56.
+In actuality, there is nothing wrong with LiteSpeed Web Server. LSWS is following the correct CloudLinux-cPanel-EA4 PHP determination work flow.
-lsphp56 was:
+  * **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.
- lsphp56-> /opt/cpanel/ea-php56/root/usr/bin/lsphp
+  * **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''.
-However somehow you changed it to the following already:
+''lsphp56'' was:
- lsphp56-> /opt/alt/php56/usr/bin/lsphp
+  lsphp56-> /opt/cpanel/ea-php56/root/usr/bin/lsphp
+You changed it to:
+  lsphp56-> /opt/alt/php56/usr/bin/lsphp
-then /opt/alt/php56/usr/bin/lsphp is differnt than cpanel default ea-php56( /opt/cpanel/ea-php56/root/usr/bin/lsphp), hence CloudLinux PHP Selector won't be used, instead, lsphp56 (/opt/alt/php56/usr/bin/lsphp) will be always used for LSWS.
+''/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.
-How to fix it? The key is to tell LSWS to use CloudLinux PHP selector instead of a particular version of alt-php.
+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 external app lsphp56 to point to PHP selector binary "/usr/local/bin/lsphp", or more easily, update php handler of suffix "php56" to served by "cl_phpselector" instead of "lsphp56".
