如何保存数据到文档里

PHP code

<?PHP    if($_POST){    $value1=$_POST['radio1'];    $value2=$_POST['radio2'];    $value3=$_POST['radio3'];    $value4=$_POST['radio4'];    $value5=$_POST['radio5'];    $value6=$_POST['radio6'];    $value7=$_POST['radio7'];    $value8=$_POST['radio8'];}?>

怎么样把$value1.....$value8保存到一个文档里。

ca。又开一贴。。文件操作。。

PHP code

    $contents = '';        $value1 = $_POST['radio1'];    $value2 = $_POST['radio2'];    $value3 = $_POST['radio3'];    $value4 = $_POST['radio4'];    $value5 = $_POST['radio5'];    $value6 = $_POST['radio6'];    $value7 = $_POST['radio7'];    $value8 = $_POST['radio8'];        $contents.="value1:{$value1}\t value2:{$value2} \t value3:{$value3}\t value4:{$value4}\t value5:{$value5}\t value6:{$value6}\t value1:{$value1}\t value1:{$value1}\t";    $handle = fopen('aa.txt',"w+");    fwrite($handle,$contents);    fclose($handle);    echo "文件写入成功";
