Step by Step solution about How to resolve the algorithm MAC vendor lookup step by step in the PHP programming language

The provided PHP code uses the curl library to interact with a web API that provides information about MAC addresses. Here's a detailed explanation:

1. API Root and MAC Address List ($apiRoot** and $macList):**

   • $apiRoot: This variable stores the base URL of the MAC vendors API, which is "https://api.macvendors.com."
   • $macList: This is an array containing a list of MAC addresses for which information will be retrieved from the API.

2. cURL Initialization ($curl = curl_init()):

   • This line initializes a cURL session. cURL is a library that allows PHP to send HTTP requests and receive responses from web servers.

3. Setting cURL Options (curl_setopt($curl, CURLOPT_RETURNTRANSFER, true)):

   • This option specifies that the output of the cURL request should be returned as a string instead of being printed directly.

4. Looping Through MAC Addresses:

   • The code enters a loop that iterates through each MAC address in the $macList array.

5. Building and Executing the API Request:

   • For each MAC address in the loop, the following steps are performed:
     • curl_setopt($curl, CURLOPT_URL, "$apiRoot/$burger"): This sets the URL of the API request to the base API URL ($apiRoot) concatenated with the current MAC address ($burger).
     • echo(curl_exec($curl)): This executes the API request using cURL and echoes the response.
     • echo("\n"): This prints a newline character after each API response.

6. Sleep Function:

   • After executing the API request for each MAC address, the code pauses for 2 seconds using the sleep(2) function. This is likely done to avoid overwhelming the API server with too many requests.

7. cURL Cleanup (curl_close($curl)):

   • Once all the API requests have been completed, the cURL session is closed using curl_close($curl).

<?php
$apiRoot = "https://api.macvendors.com";
$macList = array("88:53:2E:67:07:BE", "D4:F4:6F:C9:EF:8D", 
		 "FC:FB:FB:01:FA:21", "4c:72:b9:56:fe:bc", "00-14-22-01-23-45");

$curl = curl_init();
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
foreach ($macList as $burger) {
  curl_setopt($curl, CURLOPT_URL, "$apiRoot/$burger");
  echo(curl_exec($curl));
  echo("\n");
  sleep(2);
}
curl_close($curl);
?>
