1、查看模块是否安装并进入php模块的安装目录

[root@daixuan ext]# /usr/local/php/bin/php -m | grep -i curl

[root@daixuan ext]# pwd

/usr/local/src/php-5.4.45/ext

[root@daixuan ext]# ls 所有的模块都是可以安装的，部分已经安装

curl mssql pdo_oci simplexml tokenizer

gettext mysql pdo_odbc skeleton

date gmp mysqli wddx

[root@daixuan ext]# cd curl

[root@daixuan curl]# ls

config.m4 CREDITS interface.c package.xml streams.c

config.w32 curl.dsp multi.c php_curl.h tests


2、生成curl的模块configure可执行文件

[root@daixuan curl]# /usr/local/php/bin/phpize 生成configure可执行文件

Configuring for:

PHP Api Version: 20100412

Zend Module Api No: 20100525

Zend Extension Api No: 220100525

[root@daixuan curl]# ls

acinclude.m4 config.h.in config.w32 ltmain.sh package.xml

aclocal.m4 config.m4 CREDITS Makefile.global php_curl.h

autom4te.cache config.sub curl.dsp missing run-tests.php

build configure install-sh mkinstalldirs streams.c

config.guess configure.in interface.c multi.c tests


3、配置编译参数（如果有错，可能是缺少库）

[root@daixuan curl]# ./configure --with-php-config=/usr/local/php/bin/php-config


4、编译

[root@daixuan curl]# make

Build complete.

Don't forget to run 'make test'.


5、安装

[root@daixuan curl]# make install

Installing shared extensions:/usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/

[root@daixuan curl]# ls /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/

curl.so


6、配置PHP.ini添加curl.so模块

[root@daixuan curl]# vim /usr/local/php/etc/php.ini

添加一行：extension=curl.so

[root@daixuan curl]# /usr/local/php/bin/php -m

[PHP Modules]

bz2

Core

ctype

curl 发现curl动态模块已经加载

[root@daixuan curl]# vim vim /usr/local/php/logs/php_errors.log 如果不能加载，查看错误日志

[root@daixuan curl]# grep '^extension=' /usr/local/php/etc/php.ini 查看已经加载的动态模块

extension=curl.so


知识点：extension.dir是存放扩展模块的，在哪里呢？

[root@daixuan curl]# /usr/local/php/bin/php -i | grep extension.dir

extension_dir => /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525 => /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525

sqlite3.extension_dir => no value => no value

[root@daixuan curl]# ls /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525

curl.so


如果想修改extension.dir(扩展模块的默认目录)，该怎么做呢？

[root@daixuan curl]# vim /usr/local/php/etc/php.ini

; Directory in which the loadable extensions (modules) reside.

; http://php.net/extension-dir

; extension_dir = "./"

; On windows:

; extension_dir = "ext" 将其修改为指定的目录
