I have multiple php scripts to ping each of our locations, and I'm trying to list all results on one page.
Here's the ping script:
<?php
$host = "10.10.10.10"; //IP adress to ping
$loc = ("HQ"); //Name of location
$output = array();
echo("<b>$loc</b> <i>(IP: $host)</i> is ");
exec("ping -n 1 $host 2>&1", $output);
//print_r($output);
//you can use print_r($output) to view the output result
if (count($output) > 7) {
$output = null;
die ("<font color='green'><b>up</b></font>");
}
else {
$output = null;
die ("<font color='red'><b>down</b></font>");
}
?>
So, I have many php files with this script, where the only difference is host and loc.
I've tried to include each file in a new php file using include like this:
<?php
include "file1.php";
include "file2.php";
include "file3.php";
...and so on...
?>
But this only outputs the result of the first file.
How can I do this in any other way?
Thanks!
die(), or its equivalent exit() ends the script. Simply change die() to echo as in:
if (count($output) > 7) {
$output = null;
echo "<font color='green'><b>up</b></font>";
} else {
$output = null;
echo "<font color='red'><b>down</b></font>";
}

Here is a code I use to check if process is running under windows, in this case calc.exe
I'm trying to start calc.exe if this one not figure out in task list.
If calc.exe is not started, is opened when run php script, but page remain in a loop until i close calc.exe.
Where do I wrong?
Help is appreciated.
// START SHOW TASKLIST
// Get Tasklist
exec("tasklist 2>NUL", $task_list);
//print_r($task_list);
echo '<pre>'; print_r($task_list); echo '</pre>';
// END SHOW TASKLIST
// Service running
$kill_pattern = '~(calc)\.exe~i';
// Create array
$task_list = array();
exec("tasklist 2>NUL", $task_list);
foreach ($task_list AS $task_line) {
if (preg_match($kill_pattern, $task_line, $out)) {
echo "=> Detected: ".$out[1]."\n !\n";
$is_running = '1';
break;
}
}
if ($is_running == '1') {
echo 'Nothing to do';
exit;
} else {
// open calc.exe
exec("calc.exe");
exit;
}
Please use this code to avoid script hang up
Change
exec(calc.exe);
With
pclose(popen('start /B cmd /C "calc.exe >NUL 2>NUL"', 'r'));
I'm currently putting together a small web-based GUI to generate kickstart-scripts. I got a confirmation page that's sending the relevant data via POST to the PHP-page where the actual shell script is called to build the iso. So far it's working, but the page seems to execute the script before it outputs anything else (for example, the 'echo' I put in at the beginning of the page ...), and I'm absolutely clueless why. Would anyone care to enlighten me?
Here's the code to the PHP-page that's executing the shell script ...
echo 'Generating your ISO; this might take a while...';
sleep(20);
if (!isset($_POST['auth'])) {
$ad = 'N';
}
else {
$ad = 'Y';
}
if (!isset($_POST['oracle'])) {
$oracle = 'N';
}
else {
$oracle = 'Y';
}
if ((!isset($_POST['ip'])) or (!isset($_POST['hostname'])) or (!isset($_POST['rhsel'])) or (!isset($_POST['submit'])) or (!isset($_POST['gw'])) or (!isset($_POST['nm']))) {
die('Please use the correct form !');
}
if (isset($_POST['ip'])) {
$ip = trim($_POST['ip']);
}
if (isset($_POST['gw'])) {
$gw = trim($_POST['gw']);
}
if (isset($_POST['nm'])) {
$nm = trim($_POST['nm']);
}
if (isset($_POST['hostname'])) {
$hostname = trim($_POST['hostname']);
}
if (isset($_POST['rhsel'])) {
$rhsel = $_POST['rhsel'];
}
passthru("/usr/bin/sudo /data/skripte/webconfig.sh $rhsel $oracle $ad $ip $gw $nm $hostname 2>&1");
PHP scripts accessed via a browser are request-response, meaning all processing is done on the server prior to headers and content being sent to the client. This means you will not get a continually updating output like you would see on the command line. There is no way around this. Sorry.
How can you mimic a command line run of a script with arguements inside a PHP script? Or is that not possible?
In other words, let's say you have the following script:
#!/usr/bin/php
<?php
require "../src/php/whatsprot.class.php";
function fgets_u($pStdn) {
$pArr = array($pStdn);
if (false === ($num_changed_streams = stream_select($pArr, $write = NULL, $except = NULL, 0))) {
print("\$ 001 Socket Error : UNABLE TO WATCH STDIN.\n");
return FALSE;
} elseif ($num_changed_streams > 0) {
return trim(fgets($pStdn, 1024));
}
}
$nickname = "WhatsAPI Test";
$sender = ""; // Mobile number with country code (but without + or 00)
$imei = ""; // MAC Address for iOS IMEI for other platform (Android/etc)
$countrycode = substr($sender, 0, 2);
$phonenumber=substr($sender, 2);
if ($argc < 2) {
echo "USAGE: ".$_SERVER['argv'][0]." [-l] [-s <phone> <message>] [-i <phone>]\n";
echo "\tphone: full number including country code, without '+' or '00'\n";
echo "\t-s: send message\n";
echo "\t-l: listen for new messages\n";
echo "\t-i: interactive conversation with <phone>\n";
exit(1);
}
$dst=$_SERVER['argv'][2];
$msg = "";
for ($i=3; $i<$argc; $i++) {
$msg .= $_SERVER['argv'][$i]." ";
}
echo "[] Logging in as '$nickname' ($sender)\n";
$wa = new WhatsProt($sender, $imei, $nickname, true);
$url = "https://r.whatsapp.net/v1/exist.php?cc=".$countrycode."&in=".$phonenumber."&udid=".$wa->encryptPassword();
$content = file_get_contents($url);
if(stristr($content,'status="ok"') === false){
echo "Wrong Password\n";
exit(0);
}
$wa->Connect();
$wa->Login();
if ($_SERVER['argv'][1] == "-i") {
echo "\n[] Interactive conversation with $dst:\n";
stream_set_timeout(STDIN,1);
while(TRUE) {
$wa->PollMessages();
$buff = $wa->GetMessages();
if(!empty($buff)){
print_r($buff);
}
$line = fgets_u(STDIN);
if ($line != "") {
if (strrchr($line, " ")) {
// needs PHP >= 5.3.0
$command = trim(strstr($line, ' ', TRUE));
} else {
$command = $line;
}
switch ($command) {
case "/query":
$dst = trim(strstr($line, ' ', FALSE));
echo "[] Interactive conversation with $dst:\n";
break;
case "/accountinfo":
echo "[] Account Info: ";
$wa->accountInfo();
break;
case "/lastseen":
echo "[] Request last seen $dst: ";
$wa->RequestLastSeen("$dst");
break;
default:
echo "[] Send message to $dst: $line\n";
$wa->Message(time()."-1", $dst , $line);
break;
}
}
}
exit(0);
}
if ($_SERVER['argv'][1] == "-l") {
echo "\n[] Listen mode:\n";
while (TRUE) {
$wa->PollMessages();
$data = $wa->GetMessages();
if(!empty($data)) print_r($data);
sleep(1);
}
exit(0);
}
echo "\n[] Request last seen $dst: ";
$wa->RequestLastSeen($dst);
echo "\n[] Send message to $dst: $msg\n";
$wa->Message(time()."-1", $dst , $msg);
echo "\n";
?>
To run this script, you are meant to go to the Command Line, down to the directory the file is in, and then type in something like php -s "whatsapp.php" "Number" "Message".
But what if I wanted to bypass the Command Line altogether and do that directly inside the script so that I can run it at any time from my Web Server, how would I do that?
First off, you should be using getopt.
In PHP it supports both short and long formats.
Usage demos are documented at the page I've linked to. In your case, I suspect you'll have difficulty detecting whether a <message> was included as your -s tag's second parameter. It will probably be easier to make the message a parameter for its own option.
$options = getopt("ls:m:i:");
if (isset($options["s"] && !isset($options["m"])) {
die("-s needs -m");
}
As for running things from a web server ... well, you pass variables to a command line PHP script using getopt() and $argv, but you pass variables from a web server using $_GET and $_POST. If you can figure out a sensible way to map $_GET variables your command line options, you should be good to go.
Note that a variety of other considerations exist when taking a command line script and running it through a web server. Permission and security go hand in hand, usually as inverse functions of each other. That is, if you open up permissions so that it's allowed to do what it needs, you may expose or even create vulnerabilities on your server. I don't recommend you do this unless you'll more experienced, or you don't mind if things break or get attacked by script kiddies out to 0wn your server.
You're looking for backticks, see
http://php.net/manual/en/language.operators.execution.php
Or you can use shell_exec()

This issue came up to me in vBulletin system. i want to build a block in sidebar area to help me autmate some daily works.. i wrote php code like this :
<?php
$myDay = date('D');
$myHour = date('G');
// Saturday
if ($myDay == "Sat") {
if ($myHour >= 7) {
$output = include('textFilePath/saturday.txt');
} else {
$output = include('textFilePath/friday.txt');
}
}
// Sunday
if ($myDay == "Sun") {
if ($myHour >= 7) {
$output = include('textFilePath/sunday.txt');
} else {
$output = include('textFilePath/saturday.txt');
}
}
// and it goes on to friday...
// and in the end :
return $output;
?>
my problem is with include() function . when i return the $output value it returns a boolean(0 or 1) and include function writes out the txt files content in the beginning of document instead of "sidebar block"
i know i can echo the actual content instead of using include and txt files. but as i said i want to automate the daily tasks and give the users access to edit the txt files.
is there any other technique or function to assign the content of a local file to a variable ?
you may want to check
$output = file_get_contents('textFilePath/saturday.txt');

I've created a Perl script which connects to a host and executes some commands, and it works fine! I'm kinf of proud 'cause I'm a real newb with Perl ^^...
A overview of the perl script:
use Expect;
$|=0;
$Expect::Debug=0;
$Expect::Exp_Internal=0;
$Expect::Log_Stdout=1;
my $ip = $ARGV[0];
my $file = $ARGV[1];
my $username = $ARGV[2];
my $password = $ARGV[3];
open(CONF,$file) || die "File not found";
while(<CONF>){
$con .= $_;
}
my #conf = split("#",$con);
my $ssh = Expect->spawn("ssh -q -l $username $ip") || die "Spawn ssh failed, $!";
if($ssh->expect(5,"yes")) {
print $ssh "yes\r";
if($ssh->expect(10,"assword")) {
print $ssh "$password\r";
}
else {
warn $ssh->exp_error()."\n";
next;
}
}
elsif($ssh->expect(10,"assword")) {
print $ssh "$password\r";
}
else {
warn $ssh->exp_error()."\n";
next;
}
#Variables Globales
my $rcmd;
my #lcmd;
my $lrcmd;
$regExpCmd = "\#";
$regExpCmd2 = "^(A|B).*(\$|\#)";
$regExp = "\n";
$ssh->expect(10,$regExpCmd);
my $cmd0 = "environment no more\r";
my $cmdExit = "logout\r";
$ssh->send($cmd0);
$ssh->expect(5,$regExpCmd);
foreach my $step (#conf) {
my #lines = split("\n",$step);
foreach my $val (#lines){
$val =~ s/^\s+//;
$val =~ s/\r//;
$ssh->send("$val\r");
$i *= 1;
if(!$ssh->expect(2,$regExpCmd2)){
$i *= 0;
# if($ssh->expect(1,"MINOR")){
# die "Erreur mineur: $val";}
if($ssh->expect(2,"Error")){
die "Erreur majeur: $val";
}
}
}
$ssh->expect(1,$regExpCmd2);
}
$ssh->send($cmdExit);
print $i;
Now, I'd like to call it from PHP...
I have tried different way:
Like calling my perl script with the exec() function :
<?php
$arg1 = "MY.ADD.IP";
$arg2 = "MY/FILE";
$arg3 = "USERNAME";
$arg4 = "PASSWORD";
$result = exec("perl /path/of/perl/script.pl $arg1 $arg2 $arg3 $arg4");
if($result == 1) {
return true: }
else {
return false;
} ?>
but it is not doing anything (Checked on the remote host and so SSH connexion at all)...
I also tried using the PECL Perl interpreter for PHP, calling my script like that:
<?php
$perl = new Perl();
$perl->require('myperl.pl'); ?>
but I didn't figure how to send some arg to my script..
The fact is that I need to call it with an jQuery $.ajax request and I need to wait for the end of the script before sending back any "answer" to jQuery.
Everything I tried did not work, as the PHP script ends "before" the Perl Script...
PS: I also tried to create a Package in PERL called with PHP, like below:
package Connect;
sub new{
#Init some var... }
sub connect {
#Something like the script above.....
}
<?php
$perl = new Perl();
$perl->require('myscript.pl');
$perl->call('connect',$args);
?>
Have you ever succeeded in something like that? I really don't know what to do :(
Why don't you use ssh from php? It looks like the ssh part would be easier than what you've done in perl, and you can still get the perl regexes using preg_ functions.
PHP.net ssh2 manual page
PHP.net preg_match manual page
phpseclib, a pure PHP SSH implementation, has something very similar to expect.
An example follows:
<?php
include('Net/SSH2.php');
$sftp = new Net_SSH2('www.domain.tld');
$sftp->login('username', 'password');
echo $sftp->read('username#username:~$');
$sftp->write("sudo ls -la\n");
$output = $sftp->read('#Password:|username#username:~\$#', NET_SSH2_READ_REGEX);
echo $output;
if (preg_match('#Password:#', $lines)) {
$ssh->write("password\n");
echo $sftp->read('username#username:~$');
}
?>
It does "sudo ls -la" and waits for either "Password:" or "username#username:~".
