二，phpize 1. What is phpize phpize is used to extend php extension modules, and php plug-in modules can be created through phpize.

When installing php, you need to use phpize:

'./configure' '--prefix=/usr/local/php' '--with-mysql=/usr/local/mysql' '--with-zlib-dir' '--with -freetype-dir=/usr' '--with-jpeg-dir=/usr' '--with-png-dir=/usr' '--enable-gd-native-ttf' '--with-gd' '--enable-ftp' '--with-iconv' '--with-gettext' '--with-curl' '--enable-fastcgi' '--with-openssl'

The following parameters are the required modules. Sometimes you need to add some modules without recompiling PHP. In this case, you can use phpize to help plug-in modules.

2. How to use phpize? When php is compiled, there will be a phpize script file in the bin directory of php. Before compiling the extension module to be added, just execute the following phpize;

# If you forget to add some modules during compilation, you can use this method to recompile and add them!
# First, enter the extension directory of the PHP directory (not compiled)
cd /home/soft/php-5.2.14/ext/ftp/
# Call the phpize program to generate the compilation configuration file
# find / -name phpize
/usr /local/php/bin/phpize
Configuring for:
PHP Api Version: 20041225
Zend Module Api No: 20060613
Zend Extension Api No: 220060519
# Compile extension library
/configure –with-php-config=/usr/ local/php/bin/php-config
make
# After make is successfully executed, the generated extension library file will be in the modules subdirectory of the current directory
# Edit the php.ini document, find the directory of extension_dir, and compile the extension file Copy to extension
vim /usr/local/php/etc/php.ini
# Line 491
# extension_dir = “/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613 /”
cp ftp.so /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/
# In the add extension library location of php.ini, set the extension library to be added.
# Add extension=ftp.so at 612
# Restart webservice

Try to install a Xenforo forum on the above platform. When the installation starts, the following message is prompted: The following errors occurred while verifying that your server can run XenForo: * The required PHP extension MySQLi could not be found. Please ask your host to install this extension. * The required PHP extension GD could not be found. Please ask your host to install this extension.

Since PHP is compiled and installed from source code, the above two extensions are not installed. The following is the process of adding these two extensions to PHP:

1. Install GD extension 1. Download and install the source code package required for the GD library extension (you can click the source code package to download directly) gd-2.0.35.tar.gz http://www.libgd.org/releases/ jpegsrc.v8b.tar.gz http://www.ijg.org/ libpng-1.5.0.tar.gz http://sourceforge.net/projects/libpng/ freetype-2.4.4.tar.gz http://sourceforge.net/projects/freetype/ zlib-1.2.3.tar.gz

2. Compile and install each source code package separately 1), install zlib

tar zxvf zlib-1.2.3.tar.gz
cd zlib-1.2.3
./configure
make
make install

2), install libpng

tar zxvf libpng-1.5.0.tar.tar
cd libpng-1.5.0
cd scripts
mv makefile.linux ../makefile
cd ..
make
make install

3), install freetype

tar zxvf freetype-2.4.4.tar.gz
cd freetype-2.4.4
./configure
make
make install

4), install Jpeg

tar zxvf jpegsrc.v8b.tar.gz
cd jpeg-8b
./configure –enable-shared
make
make test
make install

Note , configure must be here You must bring the –enable-shared parameter, otherwise the shared library will not be generated.

5), install GD library

tar zxvf gd-2.0.33.tar.gz
cd gd-2.0.33
./configure –with-png –with-freetype –with-jpeg
make install
