Adding Extensions

To add Zend extensions:

1. Download the extension
   Note: - AIX Unix/Linux extensions end with the .so suffix.

2. Place the extension in your extensions directory.
   To locate the extensions directory, open the Administration Interface to Monitor | PHP Info and check the value for the directive extension_dir=.
   By default, your extensions directory is located in:
   <install_path>/zend/lib/php_extensions

3. Add the following line to your php.ini:
   zend_extension=<full_path_to_extension_so_file>

4. Restart your server.

5. To restart your server:

   Click Restart Server in the Administration Interface.

   Ensure that the extension is properly loaded by checking the output of PHPInfo in the Administration Interface.

Note:

If you try to load a PHP extension as a Zend extension, in Linux you may receive the following error message in your server's error log: "<extension_name> doesn't appear to be a valid Zend extension."
If this occurs, remove it and add it as a PHP extension, following the instructions under "To Add PHP Extensions", below.

To add PHP extensions

1. Download the third party extension. Many third party extensions can be found at http://pecl.php.net.
   Extensions are obtained directly from external web repositories.

2. Place the PHP extension in your extensions directory.
   To locate the extensions directory, open your php.ini and check the value for the directive extension_dir=.
   By default, your extensions directory is located in:
   <install_path>/lib/php_extensions

3. Add the following line to your php.ini:
   extension=<my_extension_name>.so
   Ensure that you replace <my_extension_name> with your extension's name.

4. Restart your Web server.
   Ensure that the extension is properly loaded by checking the Administration Interface: See Monitor | PHP Info for the output of PHP Info.

The extensions appear in your Administration Interface under the Extensions tab and you can use the Administration Interface to load and unload the extension.

To download extensions:

1. Go to: http://www.php.net/downloads.php.

2. In the Windows binaries section, select: "PECL <current ZendServer PHP version> Non-thread-safe Win32 binaries"  (64-bit users can use this too).

3. Click  the package to start a download process. Follow the download instructions and extract the ZIP file.

4. Select the .dll you want.

5. To add the extension, go to the extension directory, <install_path>\ZendServer\lib\phpext, and add the .dll file there.

6. Go to your php.ini file and add the following line: extension=<extension_name>.dll.

7. To verify that the extension was loaded properly, go to Setup | Extensions and locate the extension from the list.
   When loading new extensions, also examine the log files.

For more information on these extensions, go to http://pecl4win.php.net/ .

Note: The extensions in this site are thread-safe and therefore should not be downloaded for use with Zend Server .

Note:

Some extensions need directives to change the Extension's default configurations. These directives should be added added to your php.ini file manually. There is no way to predict which directives extensions may have: For each third party extension you want to add, make sure to go to the project's source site to check for additional information related to the extension.

To compile extensions from source:

1. Download and extract the extension's source.

2. Switch to the extension source directory (by default located in <install_path>/Zend/ZendServer/lib/phpext) and run the following commands:

cd <your_extension_directory>

<install_path>/bin/phpize

Ensure that you replace <your_extension_directory> with your extension directory's name.

3. Run the ./configure command to prepare the source for compilation. You will need to include the "php-config" and "enable-shared" flags as follows:

./configure --with-php-config=<install_path>/bin/php-config\

            --enable-shared

Note:

Some extensions will need additional configuration flags. It is therefore advised to run "./configure --help" and review the possible flags before compiling.

4. Compile and install the extension binaries by running the following commands:

make

make install

Make install should install the new .so extension binary in Zend Server's extension directory.

5. Add the following line to your php.ini to load your new extension:  

extension=<my_extension_name>.so

Replace <my_extension_name> with your extension's binary name.

6. Restart your Web server.

7. Ensure that the extension is properly loaded by checking the output of PHP Info. This can be viewed in the Zend Server PHP Info page.

The extension appears in your Administration Interface under the Extensions page and you can use the Administration Interface to load and unload the extension.
