1. Download PHP source code
1. Install GIT first
sudo apt-get install git
2. Clone PHP source code
cd /git clone https://github.com/php/php-src.gitls
The php-src folder is displayed.
3. Enter the ext directory
cd php-src/extls
You will see many extensions, such as curl and pdo, and the script ext_skel used to create the extension.
2. Create a skeleton to modify parameters
1. Use ext_skel to create a skeleton
./ext_skel --extname=yourname
Yourname: name of the extension you want to create. First, create one, for example, rube.
After the folder is created, the folder rube appears in the current folder.
cd rube
2. Modify the parameters of config and m4.
vim config.m4dnl Otherwise use enable: PHP_ARG_ENABLE(rube, whether to enable rube support,dnl Make sure that the comment is aligned: [ --enable-rube Enable rube support])
Remove dnl before PHP_ARG_ENABLE (rube, whether to enable rube support and [-- enable-rube Enable rube support. Modify to as shown above
3. Compile php_rube.h and rube. c.

vim php_rube.h
Add at the end of php_rube.h
PHP_FUNCTION(confirm_rube_compiled);PHP_FUNCTION(hello);
Hello, the function you want to create
2. Edit rube. c
vim rube.cconst zend_function_entry rube_functions[] = { PHP_FE(confirm_rube_compiled, NULL) PHP_FE(hello, NULL) PHP_FE_END };
Modify zend_function_entry rube_functions [] and add it after PHP_FE (confirm_rube_compiled, NULL ).
PHP_FE(hello, NULL)
3. Compile Functions
Next, write the hello function. first, write a simple function that outputs "Hello my first extention...
Add at the end of rube. c
PHP_FUNCTION(hello){char *arg = "Hello my first extention!";int len;char *strg;len = spprintf(&strg, 0, "%s\n", arg);RETURN_STRINGL(strg, len, 0);}
Save and exit
4. Compile the code
1. Compile the so file
cd /php-src/ext/rubewhereis phpize
Check whether phpize exists
If phpize is run
Sudo apt-get install php5-dev run phpize after installation
Then
./Configure -- with-php-config = Your php-config location
If the location of php-config cannot be found
whereis php-config
./Configure -- with-php-config = Your php-config location

After installation, rube. the so file will be in the modules folder in the current folder, and will also be installed in the location prompted by the system (that is, the default installation location for php extension in your system ), my prompt is as follows:
Installing shared extensions: /usr/lib/php5/20090626+lfs/
