Can PHP be used to access and manipulate ARP tables on a network interface?

To access and manipulate ARP tables on a network interface using PHP, you can use the "arp" command-line utility in PHP's `exec()` function. This allows you to execute system commands and retrieve the ARP table information. You can parse the output of the `arp -a` command to extract the ARP table entries and manipulate them as needed. 

// Execute the arp -a command to retrieve ARP table information
$arpTable = exec('arp -a');

// Parse the output to extract ARP table entries
$arpEntries = explode("\n", $arpTable);

// Manipulate the ARP table entries as needed
foreach($arpEntries as $entry) {
    // Process each ARP table entry
    echo $entry . "\n";
}
