Call to undefined function mb_internal_encoding 问题

Laravel framework error message:

[Sat May 16 11:34:36.283788 2015] [:error] [pid 9540:tid 828] [client 127.0.0.1:62578] PHP Fatal error: Call to undefined function Illuminate\ Foundation\Bootstrap\mb_internal_encoding() in E:\PHPTOOLS\Apache24\htdocs\HParent\vendor\laravel\framework\src\Illuminate\Foundation\Bootstrap\LoadConfiguration.php on line 43

Call to undefined function mb_internal_encoding() in error,

The main reason is still the configuration of the PHP.INI configuration file.

After I opened the project directory, I found that the web page could not be displayed. After using log tracking, I found the above prompt (the log is in the errlog directory under the LOGs file in the Apache folder)

I queried many websites , and finally found a similar problem on this website and tried it:

1. First check extension=php_mbstring.dll under the php.ini file Whether the extension is turned on, the extension is turned on to remove the previous; restart the Apache service

If the extension is turned on and it still doesn’t work, I recommend opening the extension of the following files and trying again (this is the case for me, I turned on all The extension can run normally)

extension=php_gd2.dll extension=php_intl.dll extension=php_mbstring.dll extension=php_exif.dll extension=php_mysql.dll extension=php_mysqli.dll extension=php_pdo_mysql.dll question reference URL:
