Installation of PHP curl extension

Sometimes after installing php, some extensions need to be added later without affecting the current work of php. We can only achieve this by dynamically adding extensions

1. First Clarify some directories

1. The source code package directory is the directory where the source code package files downloaded from the Internet are placed, which contains the downloaded php, mysql, http and other source codes

For example: /usr/local /src/

2.PHP extension package path is the software package used by PHP to support extended services. It is usually in the ext directory of the PHP source code package

For example: /usr/local/src/php-7.0.12/ext/

2. Start the installation

1. First, install the curl service, first download the curl source code package and put it in the source code Package directory

#下载源码包
（源码包列表）
https://curl.haxx.se/download/  或  https://curl.haxx.se/download.html
（或者直接下载7.55.1版本的curl包）
wget https://curl.haxx.se/download/curl-7.55.1.tar.gz
#解压
tar -zxvf curl-7.55.1.tar.gz
#进入目录
cd curl-7.55.1
#预编译（并指定安装位置）
mkdir /usr/local/lib/curl
./configure --prefix=/usr/local/lib/curl/
#安装
make && make install

2. Install the curl extension of php, remember to precompile --with-curl = /usr/local/lib/curl is the directory where curl is installed above

#进入 php 扩展包安装位置
cd /usr/local/src/php-7.0.12/ext/curl
#生成 configure 文件
/usr/local/php/bin/phpize
#预编译
./configure --with-php-config=/usr/local/php/bin/php-config  --with-curl=/usr/local/lib/curl
#安装
make && make install

3. After installation, you will be prompted to generate the curl.so file in /usr/local/php/lib/php/extensions/no-debug-zts-20151012/

4 .php.ini Turn on curl support

extension_dir="/usr/local/php/lib/php/extensions/no-debug-zts-20151012/ "

extension=curl.so Turn on Or add

5. Restart apache

There is another more common way. Many commonly used extension template php source codes have been integrated, directly enter the php extension directory /usr/local/src /php-7.0.12/ext/

Find the curl directory, enter the directory, /usr/local/php/bin/phpize, generate the configure file, ./configure --with-php-config=/usr /local/php/bin/php-config //Compile, make&make install to install; then enable the extension in php.ini;
