php7 - 7.1.2-1 - PHP is a widely-used general-purpose scripting language that is especially
 suited for Web development and can be embedded into HTML.
 This package contains only the PHP config file. You must actually choose

 Please note, that installing php5 and php7 in parallel on the same target
 is not supported in OpenWrt/LEDE.
php7-cgi - 7.1.2-1 - PHP is a widely-used general-purpose scripting language that is especially
 suited for Web development and can be embedded into HTML.
 This package contains the CGI version of the PHP7 interpreter.
php7-cli - 7.1.2-1 - PHP is a widely-used general-purpose scripting language that is especially
 suited for Web development and can be embedded into HTML.
 This package contains the CLI version of the PHP7 interpreter.
php7-fastcgi - 7.1.2-1 - As FastCGI support is now a core feature the php7-fastcgi package now depends
 on the php7-cgi package, containing just the startup script.
php7-fpm - 7.1.2-1 - PHP is a widely-used general-purpose scripting language that is especially
 suited for Web development and can be embedded into HTML.
 This package contains the FastCGI Process Manager of the PHP7 interpreter.

; Error handling and logging

; Error Level Constants:
; E_ALL             - All errors and warnings (includes E_STRICT as of PHP 6.0.0)
; E_ERROR           - fatal run-time errors
; E_RECOVERABLE_ERROR  - almost fatal run-time errors
; E_WARNING         - run-time warnings (non-fatal errors)
; E_PARSE           - compile-time parse errors
; E_NOTICE          - run-time notices (these are warnings which often result
;                     from a bug in your code, but it's possible that it was
;                     intentional (e.g., using an uninitialized variable and
;                     relying on the fact it's automatically initialized to an
;                     empty string)
; E_STRICT            - run-time notices, enable to have PHP suggest changes
;                     to your code which will ensure the best interoperability
;                     and forward compatibility of your code
; E_CORE_ERROR      - fatal errors that occur during PHP's initial startup
; E_CORE_WARNING    - warnings (non-fatal errors) that occur during PHP's
;                     initial startup
; E_COMPILE_ERROR   - fatal compile-time errors
; E_COMPILE_WARNING - compile-time warnings (non-fatal errors)
; E_USER_ERROR      - user-generated error message
; E_USER_WARNING    - user-generated warning message
; E_USER_NOTICE     - user-generated notice message
; E_DEPRECATED      - warn about code that will not work in future versions
;                     of PHP
; E_USER_DEPRECATED - user-generated deprecation warnings
;
; Common Values:
;   E_ALL & ~E_NOTICE  (Show all errors, except for notices and coding standards warnings.)
;   E_ALL & ~E_NOTICE | E_STRICT  (Show all errors, except for notices)
;   E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR  (Show only errors)
