本地Windows环境执行正常,放在Linux服务器上出现致命错误:

Fatal error:Call to undefined function com_create_guid()


原因是服务器PHP版本较高(5.4),没有内置支持com_create_guid()函数,

参见PHP官方网站安装说明( http://php.net/manual/en/com.installation.php):

"From PHP 5.4.5, COM and DOTNET is no longer built into the php core. You have to add COM support in php.ini"

所以要么在php.ini中添加com扩展,要么修改下获取GUID函数的实现以兼容各个PHP版本,如下所示:

function getGUID(){

    if (function_exists('com_create_guid')){

        return com_create_guid();

    }else{

        mt_srand((double)microtime()*10000);//optional for php 4.2.0 and up.

        $charid = strtoupper(md5(uniqid(rand(), true)));

        $hyphen = chr(45);// "-"

        $uuid = chr(123)// "{"

            .substr($charid, 0, 8).$hyphen

            .substr($charid, 8, 4).$hyphen

            .substr($charid,12, 4).$hyphen

            .substr($charid,16, 4).$hyphen

            .substr($charid,20,12)

            .chr(125);// "}"

        return $uuid;

    }

}

Copy after login
