PHP - Php Ping Command
I know that php has a function that can execute ping command but i'm not sure how it works.
I am trying to get the result of the ping command to determine: IP address has a reply (PC/device is turned on) IP address has no reply (ip address is vacant and not assigned to any pc/device IP address has a response (PC/device is turned off) is this "do-able" in php?? this is my script: Code: [Select] function ping($ip){ // #5882FA blue color indicates Fiber Module // #FACC2E orange color indicates cascade/uplink cable // #81F781 Green color indicates connected/turned on // #FE2E2E Red color indicates disconnected/turned off // #585858 dark gray color indicates connected patch panel port is vacant at user side if($ip=="Cascade" OR $ip=="Uplink"){ return $status="style=\"background-color:#FACC2E;cursor:pointer;\""; /* orange */ }elseif ($ip=="Fibre Module"){ return $status="style=\"background-color:#5882FA;cursor:pointer;\""; /* blue */ }elseif ($ip==null or $ip==""){ return $status="style=\"cursor:pointer;background-image:url(images/x.gif);\""; /* dark gray */ }else{ $str = exec("ping -n 1 -w 1 $ip", $input, $result); if ($result == 0){ return $status="style=\"background-color:#81F781;cursor:pointer;\""; /* green */ //return "on"; }else{ return $status="style=\"background-color:#FE2E2E;cursor:pointer;\""; /* red */ //return "off"; } } } i can get it display on or off and i've tested it working. but i just can't figure out if i could use this command to determine if the IP address is vacant or unassigned. I'm using this for a IP list inventory system built in PHP. I have careted a page where the the 3com switch is drawn in tabulated format with each port assigned (via PHP) to the corresponding IP address of the device/PC and indicates the port color as described in the above function. Surprisingly it works well for this switch inventory. I just want to create another page for IP address inventory using the same function. To put is simple i want to have the same function as the sofware "Advance IP-Scanner" which does the same thing as well only thing is my resources are limited to PHP (WAMP). any help guys? Similar TutorialsHow Would I ping an IP Address with Php. I am planning on using ping so that it pings a server ip, and if it matches the ip that the server is hosted on, then it will activate the profile. EG: Ping: MagicPkz.no-ip.org Comes out with my IP(70.177.**.***) Now I go to a page, it checks to see if MagicPkz.no-ip.org matches up to my IP, and if it does, it activates the profile, if it doesn't it gives an error. is this the best way to check if a server is live? <?php $host = "www.google.com"; $fp = fsockopen($host, 80, $errno, $errstr, 10); if($fp) { echo "yes it is"; fclose($fp); } else { echo "no it is not"; } ?> But if you type in a false server eg www.googddfsdfsd.com it returns an error how can i get it to return false and why doesn't it. Hello All happy new year I am trying to make a php page that detects if something is plugged in to the ethernet port. This would be complex if not impossible. I however managed to do something similar the device that will be plugged in has a static address 192.168.1.1. so I created a ping that says if the device is up or down. function ping($host, $port, $timeout) { $fP = fSockOpen($host, $port, $errno, $errstr, $timeout); $status; if ($fP) { echo "Device is ready to accept data";} else { echo "Device Down - Retrying connection"; } } What I would like to do is have a script that is constantly checking is the device is plugged or when it is not (so sort of a loop or auto detect). The idea is to have an image with the device up or down. Regards and a happy new year JG ok hi im new to the forums and didn't really know where to put this, so il put it here if its in the wrong place then im sorry, anyways currently im working on a site that will ping a server and come back with the standard Online/Offline and the MS, i've already worked on that cod and its working, one thing im not sure about though is, if its possible to only ping the server once every 2minets or so, as currently every person who comes on the site or presses F5 will ping it, i was thinking maybe somehow storing the MS ect in a database, and having the PHP read from the database and somehow every 3 minutes having it update?, but im not really sure how i would go about doing this, or even if its possible my, mySQL isn't great to say the best, il leave the PHP code below and see what you think, sorry about the code being a bit messy Code: [Select] <tr> <td class="SEBody1"> <?php // Function to check response time error_reporting(0); function pingDomain($domain) { $starttime = microtime(true); $file = fsockopen ($domain, 443, $errno, $errstr, 10); $stoptime = microtime(true); $status = 0; if (!$file) $status = -1; // Site is down else { fclose($file); $status = ($stoptime - $starttime) * 1000; $status = floor($status); } return $status; } echo '<table>'; $domainbase ="ipadress"; $status = pingDomain($domainbase); if ($status != -1) echo "<img src='img/shard_status_online.png' width='18' height='18' alt='Online' /> Online "; else echo "<img src='img/shard_status_offline.png' width='18' height='18' alt='Offline' />Offline"; echo '</table>'; ?> </td> <td class="SEBody1">Login</td> <td class="SEBody1">PvP</td> <td class="SEBody1"> <?php if ($status !=-1) echo "$status ms"; else echo "0 ms"; ?> </td> <td class="SEBody1">English</td> </tr> Hello, please can anyone advise a right solution on how to avoid my site acting strangely when one of my AD companies stops to function. I mean there are downtimes for AD servers as well, and i'm wondering what is the best solution? Can i load ads on my pages separately, so i mean lastly? They are all over my page so i guess i can't do it. Or is it better to ping ad server and wrap these ADS around PHP if functions, which ping these servers? If you have a solution , which is most effective, please tell me. 1st the log in code: Code <form method ="post" action="cartnisya.php"> <table border="0"align="right"> <td>Username:</td> <td><input type="Text" name="Username"></td> <td>  </td> <td>  </td> <td>Password:</td> <td><input type="Password" name="Password"></td> <td>  </td> <td colspan="2" align="center"><input type="Submit" name=submit" value="Submit"></td> </table> <img src="Vinnex1.jpg"> </form> it will then go the php code: CODE: <html> <?php $db = mysql_connect("localhost", "root",""); mysql_select_db("vinnex",$db); $Username = $_POST['Username']; echo $Username; $result = mysql_query("Select TransNo From transaction", $db); $myrow = mysql_fetch_array($result); if ($myrow=='') { $TransNo='1000'; $sql = mysql_query("Select * From customer where Username='$Username'", $db); $myrow1 = mysql_fetch_array($sql); $Username = $myrow1['Username']; $Firstname = $myrow1['Firstname']; $Lastname = $myrow1['Lastname']; $name = $Firstname.

Hello, I need a small php script to ping a domain with custom referrer url eg: I need a script to ping a website www.abc.com with a custom referrer url ie. xyz.com so that the website abc.com would think that the traffic is from xyz.com Anyone have an idea? --SS I found a pretty cool function that allows me to ping Pingomatic for new blogs that I have. Great. Now I can automate the process instead of manually going to their website. My problem is actually simple. Sometime Pingomatic is quite busy and is unable to receive the request. I want to be able to check the status of my ping request but I don't know how to get this specific field/variable? from the result. Here is the ping script: Code: [Select] $title = "My blog title"; $url = "http://mynewbloglink"; function pingomatic($title,$url,$debug=true) { $content='<?xml version="1.0"?>'. '<methodCall>'. ' <methodName>weblogUpdates.ping</methodName>'. ' <params>'. ' <param>'. ' <value>'.$title.'</value>'. ' </param>'. ' <param>'. ' <value>'.$url.'</value>'. ' </param>'. ' </params>'. '</methodCall>'; $headers="POST / HTTP/1.0\r\n". "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1) Gecko/20090624 Firefox/3.5 (.NET CLR 3.5.30729)\r\n". "Host: rpc.pingomatic.com\r\n". "Content-Type: text/xml\r\n". "Content-length: ".strlen($content); if ($debug) nl2br($headers); $request=$headers."\r\n\r\n".$content; $response = ""; $fs=fsockopen('rpc.pingomatic.com',80, $errno, $errstr); if ($fs) { fwrite ($fs, $request); while (!feof($fs)) $response .= fgets($fs); if ($debug) echo "<xmp>".$response."</xmp>"; fclose ($fs); preg_match_all("/<(name|value|boolean|string)>(.*)<\/(name|value|boolean|string)>/U",$response,$ar, PREG_PATTERN_ORDER); for($i=0;$i<count($ar[2]);$i++) $ar[2][$i]= strip_tags($ar[2][$i]); return array('status'=> ( $ar[2][1]==1 ? 'ko' : 'ok' ), 'msg'=>$ar[2][3] ); } else { if ($debug) echo "<xmp>".$errstr." (".$errno.")</xmp>"; return array('status'=>'ko', 'msg'=>$errstr." (".$errno.")"); } } pingomatic($title,$url,$debug=true); This script works and when Pingomatic 'is available' returns something to the effect of Thanks for pinging, you're blog is being forwarded...etc. etc. When Pingomatic is too busy I receive the following result: Code: [Select] HTTP/1.1 200 OK Server: nginx Date: Mon, 30 Apr 2012 22:23:17 GMT Content-Type: text/xml;charset=utf-8 Connection: close Content-Length: 390 <?xml version="1.0"?> <methodResponse> <params> <param> <value> <struct> <member><name>flerror</name><value><boolean>1</boolean></value></member> <member><name>message</name><value><string>Pingomatic is a bit overloaded at the moment</string></value></member> </struct> </value> </param> </params> </methodResponse> What I'm trying to get in a variable is the '<member><name>message' result. In this case it's "Pingomatic is a bit overloaded at the moment". This way I can try to ping the server again later at another time knowing that the ping was not successful. What I've tried: I've attempted to see if the 'message' (Pingomatic is a bit overloaded at the moment) is in some of the variables within the original function: $pingresponse = "<xmp>".$errstr." (".$errno.")</xmp>"; $pingresponse2 = "<xmp>".$response."</xmp>"; $pingresponse3 = array('status'=> ( $ar[2][1]==1 ? 'ko' : 'ok' ), 'msg'=>$ar[2][3] ); echo "Ping Server Response : Debug: ".$debug." Errstr :".$errstr." Errno: ".$errno."Response: ".$response; But it isn't. My plan was to use strpos to search for the term "Pingomatic is a bit overloaded at the moment" in which I'll be able to know whether or not the ping was successful or not. Any ideas? I have created a tar file with my site backup and I assume it is the full backup. Not sure becasue I can't "un"-tar the file. I have tried several ways to "unzip" or untar the file but can not come up with anything. here is how I had created the tar file: Code: [Select] $date = date("m-d-Y"); // repeat this command for multiple backups, changing the path - e.g. you can have a backup for email, another for files, etc. shell_exec("tar cvfz file_backup_$date.tar.gz mydir/ "); now how do extract it? I've created a login page in Dreamweaver and there is a redirect page for login success and login fail. What I want to have is a selection of screens based on a data field held in the user security table. Each security record will have up to 5 different security codes e.g. code1, code2 etc. If a code e.g. TA40, appears in any of the 5 code fields then I want the user directed to one page, if code TA41 appears in any of the 5 code fields then I want them directed to another page. The user code will only appear in one of the fields, but can appear in any of the 5 code fields.. How can I incorporate this in to the login screen logic, as currently it will just show the follwoing if (isset($_POST['opno'])) { $loginUsername=$_POST['opno']; $password=$_POST['pass_word']; $MM_fldUserAuthorization = ""; $MM_redirectLoginSuccess = "/menu.php"; $MM_redirectLoginFailed = "/loginform.php"; $MM_redirecttoReferrer = false; mysql_select_db($database_Hanson, $Hanson); I have a shoutbox my friend made, and I'm just adding onto it. I have command that are like @prune, @prunelogs, @logout, etc.. I am tying to make it so you can type @ban username, @unban username, etc.. Here is my command that my friend came up with. if($_POST['text'] == '@ban'.$username.'') { $unn=$idk['username']; mysql_query("UPDATE users SET banned = '1' WHERE usernane='$unn'") or die(mysql_error()); mysql_query("INSERT INTO chat (`log`, `date` ,`username` ,`text`) VALUES (1, NOW( ) , '".stripslashes($_SESSION['user'])."', 'has banned '$unn'.');") or die(mysql_error()); Hi, I'm having a weird issue when I try to run PHP scripts from the command line on my server. I'm trying to just run a very simple script to test it out: #!/usr/bin/php-cgi -q echo "Hello terminal\n"; And I get the following error in the terminal.. Code: [Select] Error in argument 1, char 3: option not found Usage: php-cgi [-q] [-h] [-s] [-v] [-i] [-f <file>] php-cgi <file> [args...] When I try taking out the quiet (-q) parameter, I get the following error.. Code: [Select] -bash: ./socket_server.php: /usr/bin/php-cgi^M: bad interpreterNo such file or directory As you can see, in the second example, a rogue "^M" was appended to the end of the first line of my socket_server.php file. What does ^M correlate to? I realize it is a character code for something that can't be represented with an actual character, but I don't know what it is, and I'm not sure why it is being appended to the end of my first line. My assumption is that this is happening in the first example too, which is why I get the "error in argument 1" message, since undoubtedly -q^M is an invalid argument... Any help is greatly appreciated! nethnet Is there anything in php that let's me SWAP 2 arrays? like let's say I have 3,2,1 in a array, is there a way I can swap the 2 and 1 if a statement is true? hello, i was wondering if there is a way to have a link do a command, but not to goto a page. my reason being is that the music player software i use has a built in web server and if you goto a certain page, it will process that command. so right now, i have an iframe that i do a target to. its pretty mickey mouse, but its what i knew how to do. thanks Hi.. I have a php file where i have only one line which says header('Location: index.php'); How do i run this php file in the terminal on fedora 14? Thanks, Rohit It was suggested that I add a ‘report’ parameter to the code, after revising with the ‘scale2ref’ code which appears to prevent the video from uploading/proceeding: $ffmpegCommand =''.$ffmpeg_b.' -y -i '.$video_file_full_path.' -i '.$watermark_image_full_path.' -filter_complex "[0]scale=426:-2[vid];[1][vid]scale2ref='oh*mdar':'ih/10'[wm][vid];[vid][wm]overlay=5:5:format=rgb,format=yuv420p" -vcodec libx264 -preset '.$pt->config->convert_speed.' -crf 26 -report'.$video_output_full_path_240.' 2>&1'; $shell = shell_exec($ffmpegCommand); I couldn’t see where the -report parameter was supposed to output (error.log has a filesize of 0). So I was asked to “run command from the shell and check”? But, I’m not sure what command and where/how to do that. I tried adding this to the php code, and attempted to upload again, same result
echo shell_exec("/usr/local/bin/ffmpeg -report log.txt 2>&1");
any additional help is appreciated
I am having difficulty working out how to grab from a URL within a URL a link to an image and display this image on a webpage. example: http://domainA.com/page1.php?file_image=http://domainB.com/image.jpg I know little of this the code below but this is not working: <?php echo $_GET['file_image']; ?> this just copies the url, whereas I want to display this image.jpg from domainB using image source by grabing it. <img src=" "> I hope you understand me. This topic has been moved to mod_rewrite. http://www.phpfreaks.com/forums/index.php?topic=326238.0 I typically only use the first two solutions. Is there anything wrong with the third? Is there any more streamlined way to do it?
function f1($x){return $x*1;}
function f2($x){return $x*1;}
$x=2;$y=1;
if(f1($x)>f2($y)){echo(f2($y)."\n");}
// or
$f2_y=f2($y);
if(f1($x)>$f2_y){echo($f2_y."\n");}
// or
if(f1($x)>$f2_y=f2($y)){echo($f2_y."\n");}
