Answer 1

If you're absolutely sure that the file exists, it seems a problem with your server. Executing the code below in terminal could solve your problem:

setsebool -P httpd_can_network_connect on

It sets the boolean value. More info: http://linux.die.net/man/8/setsebool

I think issue with your $hostname try it with: (I tried this solution with my ec2 instance and its working.)

<?php 
/* set the FTP hostname */ 
$user = "test"; 
$pass = "myFTP"; 
$host = "example.com"; 
//path of file
$file = "test.txt"; 
$hostname = $user . ":" . $pass . "@" . $host . "/" . $file; 

/* the file content */ 
$content = "this is just a test."; 

/* create a stream context telling PHP to overwrite the file */ 
$options = array('ftp' => array('overwrite' => true)); 
$stream = stream_context_create($options); 

/* and finally, put the contents */ 
file_put_contents($hostname, $content, 0, $stream); 
?>

You need to check privileges from both end:

first your AWS server bucket(your current test folder) should be public for all operations 777(I think which you already done) and the credentials you are using must have all privileges to access all files.

Note: previously I have an issue with AWS server that I have to set folder public manually by right clicking on folder.

Second thing on server on which you want to transfer; The folder or path should be public for all users(After transfer all file you can change it to read only) and with this all user has permission to write file in your targeted folder.

And code block written by @chetanAmeta seems correct.

This answer might help you.

Since offering a bounty, of course I was able to figure it out on my own (too bad I can't take my bounty back). But anyways, the solution is to mount the folder using the user of the apache server (probably "www-data"), and then the server will be able to write to the share, of course given that the rest of the permissions are set up properly.

Hope this helps someone else out, as it was very frustrating for me in the beginning.
