when compiling PHP.
Note to Win32 Users:
In order for this extension to work, there are
DLL files that must be available to the Windows
system PATH. See the FAQ titled "How do I add my PHP directory to the PATH
on Windows" for information on how to do this. Although copying DLL
files from the PHP folder into the Windows system directory also works
(because the system directory is by default in the systems
PATH), it is not recommended.
This extension requires the following files to be in the
PATH:aspell-15.dll from the
bin folder of the aspell installation.
Win32 support is available only in PHP 4.3.3 and later versions. Also, at
least aspell version 0.50 is required.
