failed to open stream: HTTP wrapper does not support writeable connections
提问by Django Anonymous
I have uploaded my localhost files to my website but it is showing me this error:-
我已将本地主机文件上传到我的网站，但它向我显示此错误：-
: [2] file_put_contents( ***WebsiteURL*** /cache/lang/ ***FileName*** .php)
[function.file-put-contents]: failed to open stream: HTTP wrapper does
not support writeable connections | LINE: 127 | FILE: /home/content/
***Folders\FileName*** .php
What i personally feel that the contents get saved in a file in cache folder and when i uploaded the files to my web server it is trying to access the cached localhost folder.
我个人认为内容保存在缓存文件夹中的文件中，当我将文件上传到我的 Web 服务器时，它试图访问缓存的 localhost 文件夹。

Instead of doing file_put_contents(***WebSiteURL***...)you need to use the server path to /cache/lang/file.php(e.g. /home/content/site/folders/filename.php).
而不是这样做，file_put_contents(***WebSiteURL***...)您需要使用服务器路径/cache/lang/file.php（例如/home/content/site/folders/filename.php）。
You cannot open a file over HTTPand expect it to be written. Instead you need to open it using the local path.
你不能打开一个文件HTTP并期望它被写入。相反，您需要使用本地路径打开它。

you could use fopen() function.
你可以使用 fopen() 函数。
some example:
一些例子：
$url = 'http://doman.com/path/to/file.mp4';
$destination_folder = $_SERVER['DOCUMENT_ROOT'].'/downloads/';
$newfname = $destination_folder .'myfile.mp4'; //set your file ext
$file = fopen ($url, "rb");
if ($file) {
$newf = fopen ($newfname, "a"); // to overwrite existing file
if ($newf)
while(!feof($file)) {
fwrite($newf, fread($file, 1024 * 8 ), 1024 * 8 );
}
}
if ($file) {
fclose($file);
}
if ($newf) {
fclose($newf);
}

May this code help you. It works in my case.
愿此代码对您有所帮助。它适用于我的情况。
$filename = "D:\xampp\htdocs\wordpress/wp-content/uploads/json/2018-10-25.json";
$fileUrl = "http://localhost/wordpress/wp-content/uploads/json/2018-10-25.json";
if(!file_exists($filename)):
$handle = fopen( $filename, 'a' ) or die( 'Cannot open file: ' . $fileUrl ); //implicitly creates file
fwrite( $handle, json_encode(array()));
fclose( $handle );
endif;
$response = file_get_contents($filename);
$tempArray = json_decode($response);
if(!empty($tempArray)):
$count = count($tempArray) + 1;
else:
$count = 1;
endif;
$tempArray[] = array_merge(array("sn." => $count), $data);
$jsonData = json_encode($tempArray);
file_put_contents($filename, $jsonData);
