Hi,

If using file_get_contents to get the status of a site or whatever and if you have entered a url that does not exist or down it will fail and produce the error...

Quote

file_get_contents() [<a href='function.file-get-contents'>function.file-get-contents</a>]: php_network_getaddresses: getaddrinfo failed: Name or service not known

So example,
I have entered a url that does not exist like....

Code Download source

http://www.php-fangree.co.uk

So this....

Code Download source

<?php
   
$url = "http://www.php-fangree.co.uk";


$contents = @file_get_contents($url);


if ($contents){
echo "<span style='color: green;'> OK</span> ";
} else {
echo "<span style='color: red;'> NOT OK</span> ";
}
        

?>

Produces the error but the point is to see if the site is on-line or not so if the site is going to be off-line or does not exist then what's the point if it is going to throw this error every time the wrong URL is entered or every time a site is down.

Now as you see in the code I have added @ before file_get_contents to suppress the error, however this will still produce the error in the PHPFusion log.

Does anyone know what I can do so it will NOT produce the error if a site is not on-line or wrong URL or can anyone show me a better way or different function to do it that will not produce errors if things are down?

Thanks

There is some kind of script checking sites on the page with the NSS list on this site. Could it be related?

The License Violations DB on next does it but I am not sure how that handles errors if the site is down or does not exist.

If you want check if site is available then you can use this function

Code Download source

   function check_url($url) {
           if(!filter_var($url, FILTER_VALIDATE_URL)) {
              return "<span style='color: orange; font-size: 14px; font-weight: bold;'>URL provided wasn't valid</span>";
           }
           $ul = curl_init($url);
           curl_setopt($ul, CURLOPT_CONNECTTIMEOUT, 10);
           curl_setopt($ul, CURLOPT_HEADER, true);
           curl_setopt($ul, CURLOPT_NOBODY, true);
           curl_setopt($ul, CURLOPT_RETURNTRANSFER, true);
           $resp = curl_exec($ul);
           curl_close($ul);
           if ($resp)
         return "<span style='color: green; font-size: 14px; font-weight: bold;'>Site seems to be up and running!</span>";
           return "<span style='color: red; font-size: 14px; font-weight: bold;'>Oops nothing found, the site is either offline or the domain doesn't exist</span>";
   }

Usage

Code Download source

   $resp = check_url("http://www.fangree.com");
   echo "<div class='resp'>".$resp."</div>";

http://www.fangree.com will give following message
Site seems to be up and running!

http://www.php-fangree.co.uk will give following message
Oops nothing found, the site is either offline or the domain doesn't exist

htp://www.php-fangree.co.uk will give following message
