However, after installing php, I installed something like PEAR, I don't want to delete the directory and reinstall it. let alone php has such a function.

I did not see it in the manual.

If I want to add bcmath support, this is an extension that supports big integer computing. Windows built-in and built-in. in linux, "this type of function is only available when PHP is compiled and configured -- enable-bcmath" (in the manual quotation marks)

Fortunately, phpize,

The method is to have a php compressed package identical to the existing php. I use php-5.2.6.tar.gz.

Expand and enter the ext/bcmath directory.

Then run/usr/local/php/bin/phpize. this is an executable text file. make sure it is in the system.

Some configure files are added to the current directory,

If no error is reported

Php code

./Configure -- with-php-config =/usr/local/php/bin/php-config

Make sure that/usr/local/php/bin/php-config exists.

If your php installation path is not the default one, change it.

If no error is reported, make, make install again, and then it tells you a directory

Copy the bcmath. so file in this directory to the directory pointed to by extension_dir in your php. ini file,

Modify php. ini and add extension = bcmath. so

Restart apache.

Success ,...
