我有一个.txt文件，其中包含用JSON编写的Windows 8应用程序列表，用于Windows 8应用程序。我希望能够有一个在线表单，我可以输入一个新的应用程序，然后将它放在JSON .txt文件中。它使用PHP file_put_contents和JSON_encode查找，但每次插入新的应用程序时，它都会将其插入新的根[]，而不是将其插入已经创建的根目录中。另一件事是pretty_printing函数不起作用，有人可以帮我把JSON输入看起来很好吗？

答案 0 :(得分：1)
请勿使用FILE_APPEND。您已经将新条目附加到$content，因此您需要完全重写该文件，而不是在旧数组之后添加新数组。
$content = json_decode( file_get_contents( $savePath ) , true );
//add the new data
$content[] = array(
'backgroundImage' => $bi ,
'description' => $ad,
'extraImages' => $ei,
'group' => array('backgroundImage' => $gbi, 'description' => $gd, 'groupImage' => $gi, 'key' => $gk, 'shortTitle' => $gst, 'title' => $gt,),
'teacherReview' => $tr,
'rating' => $rating,
'shortTitle' => $st,
'tileImage' => $ti,
'title' => $title
);
//encode the new data
$content_json = json_encode($content);
file_put_contents( $savePath , $content_json );
