为php安装zip扩展
wget http://pecl.php.net/get/zip-1.13.5.tgztar -zvxf zip-1.13.5.tgzcd 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-configmakemake install
然后修改php.ini,添加：
extension=zip.so
重启apache，查看phpinfo是否安装成功
