#4898 — Do I still CLI version of PHP

On my webserver:
*PHP version is 5.3.6
*server API: CGI/FastCGI

I need to run a socket server. A sample snippet is below:

#!/usr/local/bin/php -q

<?php

//file name: server_socket.php

.....

while (true) { // Loop continuously

// Setup clients listen socket for reading

$read[0] = $sock;

$ready = socket_select($read,null,null,null);

// If a client is trying to write - handle it now

for ($i = 0; $i < $max_clients; $i++) // for each client

{

if (in_array($client[$i]['sock'] , $read))

{

$input = socket_read($client[$i]['sock'] , 1024);

if ($input == null)

unset($client[$i]); // Zero length string meaning disconnected

$n = trim($input);

if ($input == 'exit') {

socket_close($client[$i]['sock']); // requested disconnect

} elseif ($input) {

// strip white spaces and write back to user

$output = ereg_replace("[ \t\n\r]","",$input).chr(0);

socket_write($client[$i]['sock'],$output);

}

} else {

socket_close($client[$i]['sock']);

unset($client[$i]);

}

}

} // end while

socket_close($sock);

?>



Questions:

1. Do still need the line '#!/usr/local/bin/php -q' is I call the file via 
http, eg http://domain/server_socket.php, because the program is looping ?

2. If the answer to Q1is yes, how do I run my server program (I think the 
version on my server is CGI) ?

Thanks

No, as the web service  will be calling the php interpreter, but as soon as 
you leave the "page" with your browser the script will die.

You need to have shell access and run the script in background or in a screen 
(or rewrite it so it can be run as a daemon).

AFAIK you would never run a service, especially not a PHP service, in the web server.

In the web server normal operation is Request -> Script start -> script output ->
script end ->end of request. Long running scripts are abuse.

Either run your script as true daemon, or use a "ad hoc daemon" solution like running
your script in "screen", or starting it with "nohup".
