Troubleshooting "file_get_contents() returns "failed to open stream: HTTP request failed!"

When attempting to retrieve data from a URL using PHP's file_get_contents() function, you may encounter the error "failed to open stream: HTTP request failed!". This issue arises when PHP encounters difficulties executing the HTTP request to the specified URL.

One potential cause is the presence of multiple "http://" prefixes in the URL you're trying to access. Consider removing the redundant prefix to see if it resolves the issue.

However, if the issue persists despite using a valid URL, it's advisable to try an alternative solution. One method that has proven effective is employing the cURL library.

Here's an example code snippet using cURL:

<?php

$curl_handle = curl_init();
curl_setopt($curl_handle, CURLOPT_URL, 'http://###.##.##.##/mp/get?mpsrc=http://mybucket.s3.amazonaws.com/11111.mpg&amp;mpaction=convert format=flv');
curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl_handle, CURLOPT_USERAGENT, 'Your application name');
$query = curl_exec($curl_handle);
curl_close($curl_handle);

?>
Copy after login

By using cURL, you can handle HTTP requests more reliably, often resolving the problem of failed requests experienced with file_get_contents().
