Configuration Reference article: http://blog.csdn.net/niujiaming0819/article/details/8543028
This article also uses the step process in the reference article as the native implementation process

Step 1. Download PHP source package, PHP official website to download, this time using the php5.6.8 version
Step 2. Unzip the package, into the unpacked package (mysoft$ CD php-5.6.8/), with the LS command to view the file directory in the source package, into the Ext folder (CD ext)



Step 3: Build an extended development framework  ./ext_skel--extname=helloworld

Execute the above command to establish the framework of the expansion development, this is you will find the Ext folder under a folder called HelloWorld, while the command line also output some text,

You are prompted to generate an approximate step for the extension.

Step 4. Enter the root directory of the PHP source, edit the file vim ext/helloworld/config.m4

Removing a few lines of comment from this file will roughly be between 第16-19 lines, and the specific version may be different after saving the file (: Wq)

Step 5. Executes the command in the PHP source root directory./buildconf--force

Step 6. PHP code in the root directory compiled PHP program, note the command for./configure--with-helloworld

The last error that appears, no processing

Step 7. Enter our extension directory HelloWorld, execute command phpize (install phpize via sudo apt-get install Php5-dev), at which point your extension directory generates many files that can be used for post-compilation.

Step 8. Compile our extension in the HelloWorld directory./configure--with-php-config=/usr/bin/php-config (php-config with your own environment)--enable-helloworld

You can find the location of your php-config file via a command (Find/-name Php-config) My address is/usr/bin/php-config

Step 9. Enter the extension HelloWorld directory, edit the file php_helloworld.h, add the function php_function (helloworldtest) in the last line;

HelloWorldTest can be changed to your favorite name, then save the exit

Step 10. Open HELLOWORD.C with vim, implement our function in Helloworld.c, then add HelloWorldTest function to helloworld_functions[], save exit

Step one. Do the make command make compile extension, I am running the process is still relatively smooth. If there is an error, please take a serious look at the previous step is wrong, I do the first time also wrong is generally the previous steps have a problem.

STEP12. Copy the compiled generated helloworld.so file to your native PHP extension directory

The extended directory can be passed Php-r "phpinfo ();" | grep extension_dir View the extension path for native PHP

Step 13: Configure PHP.ini to open helloworld.so extensions

View PHP.ini's location (php-r "phpinfo ();" | grep "PHP.ini")

Vim open php.ini file sudo vim/etc/php5/cli/php.ini

Add extensions at the end of a file (extension=helloworld.so)

by Php-r "Phpinfo ();" | grep HelloWorld Test

Step 14. Test the extension (php-r "echo helloworldtest ();" ）

In the process I have followed the original author's steps to try, resulting in an error

Segmentation fault "(core dumped)

After debugging, when the original author in the Helloworld.c file added to helloworld_functions[] Php_fe_end replaced with {null,null,null} and then compile the time without error but also give Php_fe_end comment , after the modification, recompile, copy on it.

Refer to the original article the author is very detailed, but in the whole process there will be a different problem, but we should have a problem-solving ideas, and a way to find answers. I also have a long time to touch technology, and recently to help friends do two sites, while trying a bit of PHP extension, feel more important when thinking.
