編譯安裝php7.3.12 和 php7.3.12 開發ext拓展

linux系統

php源碼包下載地址：https://www.php.net/downloads.php

PHP 7.3開始，開發拓展，取消了 ./ext_skel 命令工具，

要使用 php ext_skel.php 命令的形式創建拓展

一、下載源碼包解壓後，編譯安裝php

#下載源碼包  php-7.3.12.tar.gz
[root@localhost package]# wget https://www.php.net/distributions/php-7.3.12.tar.gz
[root@localhost package]# ll

-rw-r--r--. 1 root root  19457403 Nov 22 14:48 php-7.3.12.tar.gz

#解壓
[root@localhost package]# tar -zxvf php-7.3.12.tar.gz
[root@localhost package]# ll

#安裝php運行環境

[root@localhost package]# tar -zxvf libzip-1.2.0.tar.gz
[root@localhost package]# cd libzip-1.2.0
[root@localhost libzip-1.2.0]# ./configure
[root@localhost libzip-1.2.0]# make && make install
[root@localhost libzip-1.2.0]find /usr/local -iname 'zipconf.h'
[root@localhost libzip-1.2.0]ln -s /usr/local/lib/libzip/include/zipconf.h /usr/local/include

#添加搜索路徑到配置文件
echo '/usr/local/lib64

/usr/lib64'>>/etc/ld.so.conf

#更新配置
ldconfig -v


#切換目錄 ,編譯安裝 php-7.3.12
[root@localhost package]# cd php-7.3.12
[root@localhost php-7.3.12]# ./configure --prefix=/usr/local/php7.3.12 --with-config-file-path=/usr/local/php7.3.12/etc --enable-fpm --with-fpm-user=www --with-fpm-group=www --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir --with-freetype-dir=/usr/local/freetype --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --enable-intl --enable-pcntl --enable-ftp --with-gd --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-gettext --disable-fileinfo --enable-opcache --with-xsl

[root@localhost php-7.3.12]# make clean

[root@localhost php-7.3.12]# make && make install


#查看php 版本，安裝完畢
[root@localhost php-7.3.12]# /usr/local/php7.3.12/bin/php -v

具體配置php可參考另一篇文章，這裏不多說：https://blog.csdn.net/daily886/article/details/79504404

 

二、開始拓展配置

# 回到 php-7.3.12 編譯包的解壓目錄下面 ,切換到 ext 目錄
[root@localhost php-7.3.12]# cd ext

# 查看拓展使用方法
[root@localhost ext]# /usr/local/php7.3.12/bin/php ext_skel.php --help
php ext_skel.php --ext <name> [--experimental] [--author <name>]
                 [--dir <path>] [--std] [--onlyunix]
                 [--onlywindows] [--help]

  --ext <name>		The name of the extension defined as <name>
  --experimental	Passed if this extension is experimental, this creates
                        the EXPERIMENTAL file in the root of the extension
  --author <name>       Your name, this is used if --std is passed and
                        for the CREDITS file
  --dir <path>		Path to the directory for where extension should be
                        created. Defaults to the directory of where this script
 			lives
  --std			If passed, the standard header and vim rules footer used
 			in extensions that is included in the core, will be used
  --onlyunix		Only generate configure scripts for Unix
  --onlywindows		Only generate configure scripts for Windows
  --help                This help


#創建hello world 拓展
[root@localhost ext]# /usr/local/php7.3.12/bin/php ext_skel.php --ext hello_world
Copying config scripts... done
Copying sources... done
Copying tests... done

Success. The extension is now ready to be compiled into PHP. To do so, use the
following steps:

cd /path/to/php-src
./buildconf
./configure --enable-hello_world
make

Don't forget to run tests once the compilation is done:
make test TESTS=ext/hello_world/tests

Thank you for using PHP!

使用拓展的函數

編輯一個 test.php 並保存，內容如下

<?php

$test = hello_world_test2();
echo $test;
echo "\r\n";

$str = hello_world_func("daily886 done");
echo $str;
echo "\r\n";

$str2 = hello_world_func();
echo $str2;
~                          

運行 test.php ，拓展運行正常
