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