C-language php HelloWorld extension

1. Download PHP source code

wget HTTP://CN2.PHP.NET/DISTRIBUTIONS/PHP-5.6.10.TAR.GZTAR-ZXVF php-5.6.10.tar.gz

2. establish an extended development framework ./ext_skel--extname=helloworld

Cd php-5.6.10/ext/./ext_skel --extname=helloworldcreating directory helloworldcreating  basic files: config.m4 config.w32 .gitignore helloworld.c php_helloworld.h  credits experimental tests/001.phpt helloworld.php [done]. To use your new extension, you will have to execute the  FOLLOWING STEPS:1.  $ CD&NBSP, .... 2.  $ vi ext/helloworld/config.m43.  $ ./buildconf4.  $ ./ Configure --[with|enable]-helloworld5.  $ make6.  $ ./sapi/cli/php -f  ext/helloworld/helloworld.php7.  $ vi ext/helloworld/helloworld.c8.  $  makerepeat steps 3-6 until you are satisfied with ext/helloworld /config.m4 andstep 6 confirms that your module is compiled into php. then, start writingcode and repeat the last two  Steps as often as necessary.

3, enter the root directory of PHP source code, edit the file vim ext/helloworld/config.m4

Get rid of the DNL in front of these lines of code

Php_arg_enable (HelloWorld, whether to ENABLE HelloWorld support,make sure so the comment is aligned:[--enable-hellowor LD Enable HelloWorld support])

4 . Execute the command in the PHP source root directory./buildconf--force

Forcing buildconfremoving Configure cachesbuildconf:checking installation...buildconf:autoconf version 2.69 (OK) Rebuilding configurerebuilding main/php_config.h.in

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

The last error that appears, does not deal with Configure: error: xml2-config not found. please check your  libxml2 installation.

6,. 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.

CD php-5.6.10/ext/helloworldphpizeconfiguring for:php API version:20121113zend Module API No:20121212zend E XTension Api no:220121212

7 . Compile our extension in the HelloWorld directory./configure--with-php-config=/usr/bin/php-config (php-config using your own environment)-- Enable-helloworld

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

./configure --with-php-config=/usr/bin/php-configchecking for grep that handles  long lines and -e... /bin/grepchecking for egrep... /bin/grep - echecking for a sed that does not truncate output... /bin/ SEDCHECKING FOR CC ...  ccchecking whether the c compiler works... yeschecking for c  compiler default output file name... a.outchecking for suffix of  executables... checking whether we are cross compiling... nochecking  for suffix of object files... ochecking whether we are  Using the gnu c compiler... yeschecking whether cc accepts -g ...  yeschecking for cc option to accept ISO C89... none  NeededchecKing how to run the c preprocessor... cc -echecking for icc ... nochecking for suncc... nochecking whether cc understands -c  and -o together... yeschecking for system library directory...  Libchecking if compiler supports -r... no ...

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

Php_function (HelloWorldTest);

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

php_function (HelloWorldTest) {         return_string ("hello world !",  1);} const zend_function_entry helloworld_functions[] = {         php_fe (confirm_helloworld_compiled,     null)             /* For testing, remove later. */         php_fe (helloworldtest, null)          PHP_FE_END      /* Must be the last  line in helloworld_functions[] */}; 

10, execute make command make compile extension, I run 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.
