Using PHP to check status of an HTTP/FTP address??
I've got a PHP support helpdesk application that has a feature to enable the status of an HTTP or FTP address to be checked i.e. whether the address can be contacted. The method which the PHP application uses to check the HTTP/FTP address is as follows:

PHP Code:
 $noc_con = fsockopen ("$row_info[ip]", $parts[1], $errno, $errstr, 1);

            if($noc_con)
            {
                $status = "<span class=small>Running Normally &nbsp;&nbsp;<img src=../images/general/status-good.gif></span>";
            }
            else
            {
                $status = "<span class=small>Experiencing Problems &nbsp;&nbsp;<img src=../images/general/status-bad.gif></span>";
            } 


Now I'm not sure how the above works (I know very little about PHP) but regardless of whether I'm using the qualified domain name i.e. yourdomainname.com or the IP Address of the domain name to check the current status, it always outputs to the browser that their is a problem with the server. Which presumably means it can't be contacted, even though if I enter the domain name or IP Address directly into a browser I can see the website.
Can anyone explain to me how the code above is checking the status of the web site - is it basically pinging the Web/IP Address? If it is simply pinging the Web/IP Address this isn't going to work for me because the hosting company I use doesn't allow their servers to be pinged. In which case, is their any other method that someone can suggest, or even have an example of, to enable the status of an HTTP or FTP address to be checked?

ok - having looked through the PHP web site I've now got an understanding as to how the fsockopen function works. However, I'm still mystified as to why I keep getting a "false" response??!!

Any ideas??

hi madhouse!

two things come to mind

1) change the way you write your array ...

use
PHP Code:
 $noc_con = fsockopen ($row_info['ip'], $parts[1], $errno, $errstr, 1); 


2) i guess, $row_info['ip'] is coming out of a database ? if so, check the value of the element by printing it out with print or echo to check if it even holds a value ..

regards

Al

Al,

I changed the way the array was written as per your example but I still seem to be getting a false response back. I then had a look in the database table that holds the server information and their is definitely a value in there for $row_info['ip'] - the value is leapfrogmda.com.

Have you got anymore ideas?

hi again !

well, after looking at the fsockopen function, I recognized, that the last argument is the timeout setting ...

so maybe the connection would work if it had more time ...

try
PHP Code:
 $noc_con = fsockopen ($row_info['ip'], $parts[1], $errno, $errstr, 30); 


to increase the timeout to 30 seconds ...

maybe this can help

regards

al

Al - I tried changing the time out value but still no luck. I feel I may well have to abandon this feature of my helpdesk application. It's not a big loss but would've been nice to have it working.
