/* * _get_xml Gets the XML file * @access public indicates that the function is exposed externally * @param $_xmlfile XML file * $_html data array extracted from XML * */function _get_xml ($_xmlfil    E) {$_html = array ();        if (file_exists ($_xmlfile)) {$_xml = file_get_contents ($_xmlfile);               Preg_match_all ('/<vip> (. *) <\/vip>/', $_xml,$_dom);            foreach ($_dom[1] as $_value) {Preg_match_all ('/<id> (. *) <\/id>/', $_value,$_id);            Preg_match_all ('/<username> (. *) <\/username>/', $_value,$_username);            Preg_match_all ('/<sex> (. *) <\/sex>/', $_value,$_sex);            Preg_match_all ('/<face> (. *) <\/face>/', $_value,$_face);            Preg_match_all ('/<email> (. *) <\/email>/', $_value,$_email);            Preg_match_all ('/<qq> (. *) <\/qq>/', $_VALUE,$_QQ);            $_html[' id '] = $_id[1][0];            $_html[' username '] = $_username[1][0];            $_html[' sex '] = $_sex[1][0];            $_html[' face '] = $_face[1][0]; $_html['Email '] = $_email[1][0];        $_html[' qq '] = $_qq[1][0];    }}else{_alert_back ("file does not exist"); } return $_html;}

PHP writes data to an XML file

/* * _set_xml writes information to an XML file * @access public indicates that the function is publicly exposed * @param $_xmlfile XML file * @param $_clean An array of information to write * */function _set_xml ($_    Xmlfile,$_clean) {$_fp = @fopen (' Newuser.xml ', ' W '); if (!$_FP) {exit (' system error, file does not exist!    ');    } flock ($_FP,LOCK_EX);    $_string = "<?xml version=\" 1.0\ "encoding=\" utf-8\ "? >\r\t";    Fwrite ($_FP, $_string,strlen ($_string));    $_string = "<vip>\r\t";    Fwrite ($_FP, $_string,strlen ($_string));    $_string = "\t<id>{$_clean[' id ']}</id>\r\t";    Fwrite ($_FP, $_string,strlen ($_string));    $_string = "\t<username>{$_clean[' username ']}</username>\r\t";    Fwrite ($_FP, $_string,strlen ($_string));    $_string = "\t<sex>{$_clean[' sex ']}</sex>\r\t";    Fwrite ($_FP, $_string,strlen ($_string));    $_string = "\t<face>{$_clean[' face ']}</face>\r\t";    Fwrite ($_FP, $_string,strlen ($_string));    $_string = "\t<email>{$_clean[' email ']}</email>\r\t";    Fwrite ($_FP, $_string,strlen ($_string)); $_string = "\t<qq>{$_clean[' url ']}</qq>\r\t";    Fwrite ($_FP, $_string,strlen ($_string));    $_string = "</vip>";    Fwrite ($_FP, $_string,strlen ($_string));    Flock ($_fp,lock_un); Fclose ($_FP);}
