[SOLVED] accessing arrays loop

[mrjgx]

help guys. i have a problem here. whenever i tried to access the array list, this problem occurs:

 

Warning: Invalid argument supplied for foreach() in f:\mddd\www\altec\screen.php on line 120

 

//to query network client's running software

 

 

$detection = @ snmpwalk($ip_add, "public", ".1.3.6.1.2.1.25.4.2.1.2", 5);

 

 

foreach ($detection as $val) {

   

 

if ($val == "firefox.exe") {

 

echo "firefox is opened";

 

}

 

 

elseif ($val == "IEXPLORE.EXE") {

 

echo "Internet Explorer is opened";

 

}

 

 

 

}

 

 

is there something wrong? it seems that i couldnt match the array's character using the if else condition..

 

thx in advance

$detection isnt an array it is a function.

If you want it to be an array do:

$detection = array($ip_add, "public", ".1.3.6.1.2.1.25.4.2.1.2", 5);

[mrjgx]

thanks for your reply. i cannot make it into an array because it is a function that is needed.

 

$detection = array($ip_add, "public", ".1.3.6.1.2.1.25.4.2.1.2", 5);

 

i need to use the function snmpwalk to get the list of running software names.

 

i can echo $val<BR> and it will print out all the running names like this:

 

"System Idle Process"

"System"

"MDM.EXE"

"MioNetManager.exe"

"Ymsgr_tray.exe"

"avgcc.exe"

"ati2evxx.exe"

"explorer.exe"

"smss.exe"

"atiptaxx.exe"

"sm56hlpr.exe"

"csrss.exe"

"googletalk.exe"

"winlogon.exe"

"services.exe"

"lsass.exe"

"SOUNDMAN.EXE"

"ati2evxx.exe"

"svchost.exe"

"svchost.exe"

"DATALA~1.EXE"

"svchost.exe"

"TRAYAP~1.EXE"

"Apache.exe"

"SearchProtection.exe"

"daemon.exe"

"svchost.exe"

"Dreamweaver.exe"

"PhiBtn.exe"

"svchost.exe"

"Tray900.exe"

"AppleMobileDeviceService.exe"

"ctfmon.exe"

"spoolsv.exe"

"avgamsvr.exe"

"Apache.exe"

"WLANUTL.exe"

"avgupsvc.exe"

"avgemc.exe"

"DkService.exe"

"SERVIC~1.EXE"

"ijplmsvc.exe"

"sqlservr.exe"

"MioNet.exe"

"mysqld.exe"

"snmp.exe"

"svchost.exe"

"firefox.exe"

"wdfmgr.exe"

"IEXPLORE.EXE"

"alg.exe"

"wscntfy.exe"

"svchost.exe"

 

 

i need to know how to match the list of names using the loop? is there a way to do that??

 

thanks

The function snmpwalk() returns an array. Since you prefixed the function call with the "@", you're suppressing any error message that might be coming from the function. Remove the "@" and see if an error is returned.

there no point in that code as the .exe program is there even if you dont execute it......

 

unless that what the third parameter for....

 

please tell me..

[mrjgx]

ok now i finally got no errors. the code runs well, only thing that i need to know is how to match the arrays from snmpwalk function into the if-else condition.

 

by using this code:

 

foreach ($detection as $val) {

 

    if ($val == "firefox.exe") {

 

      echo "firefox is opened";

 

  }

     

  elseif    ($val == "IEXPLORE.EXE") { 

 

      echo "Internet Explorer is opened";

     

  }

 

}

 

but the echo doesnt appear, meaning that it cannot match the array names. is there a way to access the arrays 1 by 1 and match the strings using if-else condition?

 

thank you.

[redarrow]

you can try that......

<?php

$val= snmpwalk($ip_add, "public", ".1.3.6.1.2.1.25.4.2.1.2", 5);

     if (in_array("firefox.exe",$val)) {
   
      echo "firefox is opened";
   
   }
     
   elseif (in_array("IEXPLORE.EXE",$val)) {   
   
      echo "Internet Explorer is opened";
     
   }

}
?>

 

you sure the elseif is even valid say you use both i do...

[mrjgx]

Thanks for the reply..but i get this error message instead.

 

Warning: in_array(): Wrong datatype for second argument in f:\mddd\www\altec\screen.php on line 120

Warning: in_array(): Wrong datatype for second argument in f:\mddd\www\altec\screen.php on line ....

Warning: in_array(): Wrong datatype for second argument in f:\mddd\www\altec\screen.php on line ....

Warning: in_array(): Wrong datatype for second argument in f:\mddd\www\altec\screen.php on line ...n

 

is there a way to rectify that?

 

thanks

[redarrow]

[mrjgx]

can you explain what is the use of  $x=$re[]; ?

 

anyway i got error message :

 

  Fatal error: Cannot use [] for reading in f:\mddd\www\altec\screen.php on line 120

 

 

huhu 'm lost  ???

 

[redarrow]

take no notice off my code example m8 i have not got this function installed sorry

have to wait for a diffrent user to help you...........

[mrjgx]

thanks anyway for your help 

 

so is there someone out there can help me then?  :'(

[teng84]

i believe this is none sense

can you explain what is the use of  $x=$re[]; ?  if you dont get an error out of that you will get empty

[hitman6003]

are you sure that your snmpwalk function is returning the results you are expecting?

 

use print_r to view the contents of the array:

 

echo '<pre>' . print_r($detection, true) . '</pre>';

 

if it is an array, then use some normalization on the data returned to make sure it's matching your string:

 

if (in_array("firefox.exe",strtolower(trim($val)))) {
echo "firefox is opened";
} else if (in_array("iexplore.exe",strtolower(trim($val)))) {   
echo "Internet Explorer is opened";
}

[mrjgx]

hey thanks..the print_r function will displays this list:

 

Array

(

    [0] => "System Idle Process"

    [1] => "System"

    [2] => "MDM.EXE"

    [3] => "MioNetManager.exe"

    [5] => "avgcc.exe"

    [6] => "ati2evxx.exe"

    [7] => "explorer.exe"

    [8] => "smss.exe"

    [9] => "atiptaxx.exe"

    [10] => "sm56hlpr.exe"

    [11] => "csrss.exe"

    [12] => "googletalk.exe"

    [13] => "winlogon.exe"

    [14] => "services.exe"

    [15] => "lsass.exe"

    [16] => "SOUNDMAN.EXE"

    [17] => "ati2evxx.exe"

    [20] => "DATALA~1.EXE"

    [21] => "svchost.exe"

    [22] => "TRAYAP~1.EXE"

    [23] => "Apache.exe"

    [24] => "SearchProtection.exe"

    [25] => "daemon.exe"

    [26] => "svchost.exe"

    [27] => "Dreamweaver.exe"

    [28] => "PhiBtn.exe"

    [29] => "svchost.exe"

    [30] => "Tray900.exe"

    [31] => "AppleMobileDeviceService.exe"

    [32] => "ctfmon.exe"

    [33] => "spoolsv.exe"

    [50] => "alg.exe"

    [51] => "wscntfy.exe"

    [52] => "svchost.exe"

)

 

 

but the normalization on the data returned this error message:

 

Warning: in_array(): Wrong datatype for second argument in f:\mddd\www\altec\screen.php on line 124

 

 

i need to know how to excerpt the array which have firefox or iexplorer words in it..is there a way?

thx guys

 

 

 

[kenrbnsn]

Try this:

<?php
$val= snmpwalk($ip_add, "public", ".1.3.6.1.2.1.25.4.2.1.2", 5);
foreach ($val as $exe)
    switch ($val) {
          case 'IEXPLORE.EXE':
              echo "Internet Explorer is opened";
              break;
          case 'firefox.exe':
              echo "firefox is opened";
              break;
    }
?>

[mrjgx]

Thanks kenrbnsn..your switch code is kind same with my original switch code that i made..

 

finally i found the solutions to this problem...i just need to put the " ".

 

this is the working code:

 

foreach ($val as $exe)

 

    switch ($exe) {

         

  case '"IEXPLORE.EXE"':

              echo "Internet Explorer is opened<BR>";

                break;

       

 

case '"firefox.exe"':

            echo "firefox is opened<BR>";

            break;

 

 

    }

 

voila..all the problems solved..i can access each items in the array list...

 

MILLION THANKS to all helpers. i'm so happy
