 ===== PHP Auto Configuration for Different Control Panels =====
-In previous version lower than LSWS 5.2.x, there is a "External App" section to setup PHP external apps and a "Script Hander" section to setup PHP handlers.
+In previous versions of LSWS (5.2.x and earlier), external apps and PHP handlers are set up via the **External App** and **Script Hander** sections, respectively.
 {{ :litespeed_wiki:php:lsws5.3-php-detached-mode-php-externalapp.png?800 |}}
-On LSWS 5.3,  PHP external app and PHP script handler configurations are not required anymore and they will be autoconfigured by the web server. If you run upgrade from 5.2.x or previous version, external apps settings will be carried over. Actually you can delete all PHP external apps and PHP handlers and LSWS will still be working fine. If you install a new fresh LSWS 5.3 installation, most likely you won't see any PHP external apps and PHP handlers defined there anymore. If you see such, don't worry and it is normal for LSWS 5.3. If you still want to define external apps manually, it is ok, and LSWS will honor the settings which actually override the LSWS 5.3 built-in external apps definition.
+On LSWS v5.3 and above, these configurations are no longer required. External apps and script handlers will be autoconfigured by the web server. If you upgrade to v5.3 from an earlier version, the external apps settings will be carried over. (However, you could delete all PHP external apps and PHP handlers and LSWS would still work fine.)
+If you install a new fresh LSWS 5.3 installation, you probably won't see any PHP external apps or PHP handlers defined there. Don't worry. This is normal. If you still want to define external apps manually, you can do so. LSWS will honor these settings, and they will override the built-in external apps definition.
-How to configure PHP setting then if there are no external apps defined there anymore? While a new "PHP" tab has been created in LSWS Web Admin Console and you can set configuration there to detached PHP.
+Currently, LSWS auto-detects apps and handlers up to PHP 7.3. Two handlers: ''application/x-httpd-ea-php71'' and ''application/x-httpd-alt-php71'' now point to separate handlers, where prior to 5.3, both pointed to the lsphp71 handler configuration.
+So, how do you configure PHP settings if there are no external apps defined there anymore? See the new **PHP** tab in the Web Admin console to adjust the configuration.
+Configurations set under the **PHP** tab or in the ''<phpConfig>'' section, serve as the default for auto-detected PHP handlers, so the memory limit set there will apply to all detected PHP handlers. An explicitly configured PHP handler will still use its own configuration.

 Change the PHP binary path:

+===== ea-phpxx and alt-phpxx are different handlers on LSWS 5.3 while same on LSWS 5.2.x and below =====
+LSWS 5.3 speically adds alt-phpxx(CloudLinux PHP selector) handlers' suppport for cPanel and CloudLinux system hence alt-phpxx are different than ea-phpxx. On previous version of LSWS 5.2.x and below, there is no separate handler between alt-phpxx and ea-phpxx
+and both of them use ea-phpxx handlers.
+The above feature will support latest cPanel multi-PHP manager more friendly since either alt-phpxx or ea-phpxx can be selected for a domain, instead of just ea-phpxx only. Then cPanel will add the following to .htaccess depending on which php was selected. LSWS 5.3 will use alt-phpxx or ea-phpxx according to user's choice.  On LSWS 5.2.x and below version, LSWS will only set ea-phpxx no matter alt-phpxx or ea-phpxx selected.
+  AddType application/x-httpd-alt-php70 .php .php7 .phtml
+or
+  AddType application/x-httpd-ea-php70 .php .php7 .phtml
+On LSWS 5.2.x, if you set all lsphpxx binary to use alt-phpxx for all handlers and set some per directory php as the following by using ea-phpxx in .htaccess.
+  AddType application/x-httpd-ea-php54 .php .php7 .phtml
+or
+  <FilesMatch ".(php4|php5|php3|php2|php|phtml)$">
+  SetHandler application/x-httpd-ea-php54
+  </FilesMatch>
+It works with LSWS 5.2.x but doesn't work with LSWS 5.3. Why?
+LSWS 5.3 treats ea-phpXX handler and alt-phpXX handler separately.
+If the server only have ea-php70 installed and other ea-phpXX handler is not available, then
+  SetHandler application/x-httpd-ea-php54
+or
+  SetHandler application/x-httpd-ea-php55
+will fail.
+.2.x treat ea-phpXX and alt-phpXX handler the same and handled by lsphpXX handler which pointing to alt-php binary.
+How to fix it?
+==== Method1: You should use right Handler for LSWS 5.3 now ====
+In .htaccess, you should change:
+  SetHandler application/x-httpd-ea-php54
+to
+  SetHandler application/x-httpd-alt-php54
+and you should use the right one moving forward. But it seems a little time consuming to change all handler settings in all .htaccess for 5.2.x to 5.3 migration. There is another way as the following:
+==== Method2: Make LSWS 5.3 behaves as 5.2.x ====
+Instead of scanning .htaccess to fix wrong handler configuration, it is possible to make 5.3 behave the same as 5.2.x.
+Please update the name of lsphpXX external app from lsphpXX to ea-phpXX, the executable path is still pointing to alt-php binary. this way, ea-phpXX, alt-phpXX, and lsphpXX are all handled by alt-php handlers.
