OUTPUT

PHP Script To Get A Mac Address Of User/Client

Logic 1 :

<?php 
/* 
* Getting MAC Address using PHP 
* Mr. Vetrivel Samidurai 
*/ 

ob_start(); // Turn on output buffering 
system('ipconfig /all'); //Execute external program to display output 
$mycom=ob_get_contents(); // Capture the output into a variable 
ob_clean(); // Clean (erase) the output buffer 

$findme = "Physical"; 
$pmac = strpos($mycom, $findme); // Find the position of Physical text 
$mac=substr($mycom,($pmac+36),17); // Get Physical Address 

echo $mac; 
?>

Logic 2 :


$ipAddress=$_SERVER['REMOTE_ADDR'];

#here U can run external command

$arp=`arp -a $ipAddress`;
$lines=explode("n", $arp);

#looking up the arp U need
foreach($lines as $line){
$cols=preg_split('/s+/', trim($line));
if ($cols[0]==$ipAddress)
$macAddr=$cols[1];
}

What Is The Meaning Of S In OOPS

This is most common misunderstood short form related to object oriented paradigm. If somebody asks which paradigm you use or on which paradigm Java works. We generally answer it as OOPS or OOPs. And here we do mistake. Also this came as a conundrum when interviewer asked to my buddy what “s” stands for.

First grab the full form, then I will explain it further—

Differentiate OOPS and OOP

Oops!! Yes. This is the sound you must whisper. Well OOP you already know, following is the definition of OOPS (actually oops – not in CAPS)

Yes this is official definition of oops.

******************************************************************************

Some other views of Programmers related to the full form of OOPs or the meaning of s in OOPs

1. OOPs - Object oriented programming system

2. OOPs - Object oriented programming structure

3. OOPS is commonly a misused abbreviation. Originally it is OOP - Object Oriented Programming or     might refer toObject Oriented Programming LanguageS 

4. s indicates Plurality or multiplicity at the end of a word in the English language. But in general s in oops is System.
