How to add extension libraries for PHP in Linux

What problems will occur when I add them, and what errors will be reported if I do not add them. Therefore, when compiling PHP, many parameters are not added except the necessary directory settings ...... When I installed the web program, I found that many parameters need to be added, but I have already set up lnmp and do not want to re-compile and reinstall it .. So I found this article online.

1. add FTP Extension

1. Find the original source code package and decompress it.
Such as: php-5.2.13
Go to the FTP extension directory/root/lnmp/php-5.3.0/ext/ftp

2. Call the phpize program to generate the compilation configuration file.

Copy codeThe Code is as follows: root @ dns ftp] #/usr/local/php5/bin/phpize
Processing ing:
PHP Api Version: 20041225
Zend Module Api No: 20060613
Zend Extension Api No: 220060519

3. Compile the extension library and execute the following configure and make commands respectively.

#./Configure -- with-php-config =/usr/local/php5/bin/php-config

# After configure passes this step, run the make command. If configure fails, find the cause of the error.

# Make

# After make is successfully executed, the generated extension library file is in the modules subdirectory of the current directory,

Copy codeThe Code is as follows: [root @ Ansen ftp] # ls modules/
Ftp. la ftp. so

4. Edit the php. ini file, create the extension_dir directory, and copy the compiled extension file to the extension directory.

Change extension_dir = "./"

Copy codeThe Code is as follows: extension_dir = "/usr/local/php5/lib/php/extension"

Copy codeThe Code is as follows: [root @ Ansen modules] # cp ftp. so/usr/local/php5/lib/php/extension

5. Add the extension library location in php. ini and set the extension library to be added.
Add extension = ftp. so in section 989

6. Restart apache to get ftp support.

Ii. Add zlib Extension

Copy codeThe Code is as follows: [root @ Ansen zlib] # pwd
/Root/lnmp/php-5.3.0/ext/zlib
[Root @ Ansen zlib] # mv config0.m4 config. m4
[Root @ Ansen zlib] #/usr/local/php5/bin/phpize
[Root @ Ansen zlib] #./configure -- with-php-config =/usr/local/php5/bin/php-config
[Root @ Ansen zlib] # make
[Root @ Ansen zlib] # cp modules/zlib. so/usr/local/php5/lib/php/extension/
[Root @ Ansen zlib] # vi/usr/local/php5/lib/php. ini
Add extension = zlib. so

8. Restart apache.

PS: for other extensions, refer to the above two extension methods for installation.

Supplemented with the simplified version:

I forgot to compile php at the beginning. Now I am using phpize to install the extension library and add it.
Locate the source code directory of the currently running php version, such as the php-5.2.12. Enter the curl extension library directory
# Cd/home/changyou/php-5.2.12/ext/curl
(Call the phpize program to generate the compilation configuration file)
#/Usr/local/web/php/bin/phpize
(Compile the extension library and execute the following configure and make commands respectively)
#./Configure-with-php-config =/usr/local/web/php/bin/php-config
(After configure passes this step, execute the make command. If configure fails, find the cause of the Error)
# Make
After make is successfully executed, the generated extension library file is in the modules subdirectory of the current directory.
My directory here is:/home/changyou/php-5.2.12/ext/curl/modules/curl. so
Configure the php. ini file and copy the compiled extension library file to the extension directory of php.
# Cp/home/changyou/php-5.2.12/ext/curl/modules/curl. so/usr/local/web/php/lib/php/extension/
Finally, modify php. ini to add the configuration.
Extension_dir = "/usr/local/web/php/lib/php/extension /"
Extension = curl. so

Done !!!
