How to install PHP extension bcmath

I forgot to add an extension when compiling php. I wanted to add an extension later, but because I installed some things such as PEAR after installing php, I didn’t want to delete the directory and reinstall it. Not to mention, php really has such a function. Below, the editor will take you through how to install and install the bcmath extension.

Common problems with using PHP are: forgetting to add an extension when compiling PHP, and later want to add the extension, but because after installing PHP, some things such as PEAR are installed, so I don’t want to Delete the directory and reinstall it. Not to mention, php really has such a function.

I didn't see it in the manual.

If I want to add bcmath support, this is an extension that supports large integer calculations. Windows comes with it and is built-in. Linux "This type of function is only available when --enable-bcmath is configured when PHP is compiled" (the quotes are from the manual)

Fortunately, phpize is available,

The method is to have a php compressed package that is exactly the same as the existing php. I'm using php-5.2.6.tar.gz.

After expansion, enter the ext/bcmath directory inside

Then execute /usr/local/php/bin/phpize. This is an executable text file. Make sure it is in the system

You will find that there are some more configure files in the current directory.

If no error is reported, then

Php code

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

Please make sure that /usr/local/php/bin/php-config exists first.

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

If no error is reported, make, then make install, and then it will tell you a directory

You copy bcmath.so in that directory to the directory pointed to by extension_dir in your php.ini ,

Modify php.ini and add extension=bcmath.so at the end

Restart apache.
