; If you wish to have an extension loaded automatically, use the following
; syntax:
;
;   extension=modulename
;
; For example:
;
;   extension=mysqli
;
; When the extension library to load is not located in the default extension
; directory, You may specify an absolute path to the library file:
;
;extension=/path/to/extension/mysqli.so
;
; Note : The syntax used in previous PHP versions ('extension=<ext>.so' and
; 'extension='php_<ext>.dll') is supported for legacy reasons and may be
; deprecated in a future PHP major version. So, when it is possible, please
; move to the new ('extension=<ext>) syntax.
;
; Notes for Windows environments :
;
; - Many DLL files are located in the extensions/ (PHP 4) or ext/ (PHP 5+)
;   extension folders as well as the separate PECL DLL download (PHP 5+).
;   Be sure to appropriately set the extension_dir directive.
