我正在尝试将从数据库中检索到的数据保存到.json中。这就是刚刚尝试过的。
$sql = mysql_query("SELECT `positive`,`time` FROM sentiment WHERE acctid=1");
$response = array();
$posts = array();
while($row=mysql_fetch_array($sql))
{
$positive=$row['positive'];
$time=$row['time'];
$posts[] = array('positive'=> $positive, 'time'=> $time,);
}
$response['posts'] = $posts;
$fp = fopen('results.json', 'w');
fwrite($fp, json_encode($response));
fclose($fp);
我收到了以下错误:
Warning: fopen(results.json) [function.fopen]: failed to open stream: Permission denied in /Applications/XAMPP/xamppfiles/htdocs/test/getjson.php on line 29
Warning: fwrite() expects parameter 1 to be resource, boolean given in /Applications/XAMPP/xamppfiles/htdocs/test/getjson.php on line 30
Warning: fclose() expects parameter 1 to be resource, boolean given in /Applications/XAMPP/xamppfiles/htdocs/test/getjson.php on line 31
问题是什么?
答案 0 :(得分:2)
Apache无法写入文件夹/Applications/XAMPP/xamppfiles/htdocs/test
- 更改权限以便它可以写入。在Windows资源管理器中,右键单击test
文件夹,然后取消选中“只读”。
