为php安装zip扩展

wget http://pecl.php.net/get/zip-1.13.5.tgz
tar -zvxf zip-1.13.5.tgz
cd zip-1.13.5
/home/xxx/php/bin/phpize

出现错误：

Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable. Then, rerun this script.

解决方法：

 yum install m4
 yum install autoconf

再安装：

/home/xxx/php/bin/phpize
./configure  --with-php-config=/home/xxx/php/bin/php-config
make
make install

然后修改php.ini,添加：

extension=zip.so

重启apache，查看phpinfo是否安装成功
