fopen函数写入数组，并取出数组

写入数组并序列化

$filename="data.txt";
$file_hwnd=fopen($filename,"w");
fwrite($file_hwnd,serialize($arr)); //输入序列化的数据
fclose($file_hwnd);

取出数组

$filename="data.txt";
$file_hwnd=fopen($filename,"r");
$content = fread($file_hwnd, filesize($filename)); // 读去文件全部内容
fclose($file_hwnd);
$arr = unserialize($content);

$new_arr = unserialize($content); //反序列化操作

写入新的数组并覆盖

$myfile = fopen("data.txt", "w") or die("Unable to open file!");
fwrite($myfile, serialize($new_arr));//serialize因个人需要序列化操作
fclose($myfile);
