Today I updated the PHP install on my Windows development box. Initially I kept getting weird errors about php_mbstring.dll and php_exif.dll not being found. I checked the extension path carefully. Then, I saw in the PHP 4.3.11 install file:
php_exif.dll EXIF functions [requires] php_mbstring.dll. And, php_exif.dll must be loaded after php_mbstring.dll in php.ini.
If that's the case, it makes sense to me to list the line for php_exif.dll
after the line for php_mbstring.dll (currently php_exif.dll appears first), or at least place that install comment into the php.ini file!
