PHPWarning [PHP problem] PHP Warning: PHP Startup: Unable to load dynamic library 'C:/AppServ \ php5

I wrote a program for data import, and found that the error that cannot be loaded on the page is reported if it is always half executed.
A log is found.

PHP Warning :? PHP Startup: Unable to load dynamic library 'E: /AppServ/php5/ext \ php_exif.dll '-\ xd5 \ xd2 \ xb2 \ xbb \ xb5 \ xbd \ xd6 \ xb8 \ xb6 \ xa8 \ xb5 \ xc4 \ xc4 \ xa3 \ xbf \ xe9 \ xa1 \ xa3 \ r \ n in Unknown on line 0

So I searched online for the loading issue of php_exif.dll and found a piece of content about php memory allocation and php_exif.dll. it was very bright and I realized that the page could not be accessed due to the failure of php memory allocation.
The original php_exif.dll requires php_mbstring.dll extension. AndMust be inPhp_mbstring.dll is enabled before php_exif.dll, so
Php_mbstring.dll must be loaded before php_exif.dll is loaded. Unfortunately, php. ini is loaded in alphabetical order. manually change the loading order and restart apache. OK!
