问题 Here's my code: $language = $_GET['soundtype']; $word = $_GET['sound']; $word = urlencode($word); if ($language == 'english') { $url = "<the first url>"; } else if ($language == 'chinese') { $url = "<the second url>"; } $opts = array( 'http'=>array( 'method'=>"GET", 'header'=>"User-Agent: <my user agent>" ) ); $context = stream_context_create($opts); $page = file_get_contents($url, false, $context); header('Content-Type: audio/mpeg'); echo $page; But I've found that this runs terribly slow.

Can't get remote filename to file_get_contents() and then store file

阅读更多关于 Can't get remote filename to file_get_contents() and then store file

I want to download a remote file and put it in my server directory with the same name the original has. I tried to use file_get_contents($url) . Problem is that the filename isn't included in $url , it is like: www.domain.com?download=1726 . This URL give me, e.g.: myfile.exe , so I want to use file_put_contents('mydir/myfile.exe'); . How could I retrieve the filename? I tried get_headers() before downloading, but I only have file size, modification date and other information, the filename is missing. I solved it another way. I found that if there is no content-disposition in url headers, then

阅读更多关于 HTTP/1.1 505 HTTP Version Not Supported

I'm running a PHP script to grab a web page. It worked fine with many sites, but with one site it fails, returning an error saying "HTTP/1.1 505 HTTP Version Not Supported". This is (part of) my script: for($i = 0; $i < 1; $i++) { $page = file_get_contents("http://www.lovelybooks.de/stoebern/empfehlung/romantic fantasy/?seite=$i"); // do something with $page } Many answers recommend setting the HTTP version explicity.

faster fopen or file_get_contents?

阅读更多关于 faster fopen or file_get_contents?

i am running multiple websites with high traffic , as a requirement , all images are downloaded via image.php?id=IMAGE_ID_HERE . If you ever done that before , you know that that file will be reading the file image and echoing it to the browser with special headers . My problem is , the load on the server is very high (150-200) and TOP command shows multiple instances of image.php , so image.php is running slow ! the problem probably is fopen loading the image to the memory before sending it to the client. How to read a file and pass it through directly? Thank you guys UPDATE After you
