php解析XML获取标签中的值
/*
* _get_xml 获取的XML文件
* @access public 表示函数对外公开
* @param $_xmlfile xml文件
* $_html 从XML中取出的数据数组
* */
function _get_xml($_xmlfile){
$_html = array();
if(file_exists($_xmlfile)){
$_xml = file_get_contents($_xmlfile);
preg_match_all('/(.*)/', $_xml,$_dom);
foreach($_dom[1] as $_value){
preg_match_all('/(.*)/', $_value,$_id);
preg_match_all('/(.*)/', $_value,$_username);
preg_match_all('/(.*)/', $_value,$_sex);
preg_match_all('/(.*)/', $_value,$_face);
preg_match_all('/(.*)/', $_value,$_email);
preg_match_all('/(.*)/', $_value,$_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("文件不存在");
}
return $_html;
}
php向XML文件中写入数据
/*
* _set_xml将信息写入XML文件
* @access public 表示函数对外公开
* @param $_xmlfile xml文件
* @param $_clean 要写入的信息的数组
* */
function _set_xml($_xmlfile,$_clean){
$_fp = @fopen('newuser.xml','w');
if(!$_fp){
exit('系统错误，文件不存在！');
}
flock($_fp,LOCK_EX);
$_string = "\r\t";
fwrite($_fp, $_string,strlen($_string));
$_string = "\r\t";
fwrite($_fp, $_string,strlen($_string));
$_string = "\t{$_clean['id']}\r\t";
fwrite($_fp, $_string,strlen($_string));
$_string = "\t{$_clean['username']}\r\t";
fwrite($_fp, $_string,strlen($_string));
$_string = "\t{$_clean['sex']}\r\t";
fwrite($_fp, $_string,strlen($_string));
$_string = "\t{$_clean['face']}\r\t";
fwrite($_fp, $_string,strlen($_string));
$_string = "\t{$_clean['email']}\r\t";
fwrite($_fp, $_string,strlen($_string));
$_string = "\t{$_clean['url']}\r\t";
fwrite($_fp, $_string,strlen($_string));
$_string = "";
fwrite($_fp, $_string,strlen($_string));
flock($_fp,LOCK_UN);
fclose($_fp);
}
