PHP代碼說明

Question

我遇到了這段php代碼，我想知道有沒有人知道這個代碼的原始來源和目的以及實現。

<?php 

require "twilio/Services/Twilio.php"; 

function sqlconnect() 
{ 
    $dbhost="localhost";   //database host 
    $dbuser="root";   //database username 
    $dbpassword="xxxxxx";  //database password  
    $dbname="xxxxx";   //database name 
    $db = mysql_connect($dbhost,$dbuser,$dbpassword) or die("Couldn't connect to the database."); 
    mysql_select_db($dbname) or die("Couldn't select the database"); 
    return($db); 
} 

function sendsms($msg) { 
    $AccountSid = "xxxxx"; //twilio settings 
    $AuthToken = "xxxx"; //twilio settings 
    $client = new Services_Twilio($AccountSid, $AuthToken); 
// $sms = $client->account->sms_messages->create("xxxx", "+xxxx", $msg); //twilio settings 
    $sms = $client->account->sms_messages->create("6xxxx", "+xxxx", $msg); //twilio settings 
    echo"\n\nSending SMS\n\n"; 
} 

$queue = array(); 

//////// setup our named pipe //////// 

$pipefile = '/tmp/aironetpipe'; 
if(file_exists($pipefile)) 
    if(!unlink($pipefile)) 
     die('unable to remove stale file'); 

umask(0); 
if(!posix_mkfifo($pipefile,0666)) 
    die('unable to create named pipe'); 

$pipe = fopen($pipefile,'r+'); 
if(!$pipe) die('unable to open the named pipe'); 
stream_set_blocking($pipe,false); 

//////// process the queue //////// 
while(1) { 

    while($input = trim(fgets($pipe))) { 
     stream_set_blocking($pipe,false); 
     $queue[] = $input; 
    } 

    $job = current($queue); 
    $jobkey = key($queue); 
    if($job) { 
     echo '\n\nprocessing job ', $job, PHP_EOL; 

     //process($job); 


     if (strstr($job, "-ASSOC")) { //check for association 
         $db = sqlconnect();    
         $match = "/(?<=Station)(.*)(?=Associated)/"; 
         preg_match($match, $job, $regexresult); 
           $mac = trim($regexresult[0]); 
           if ($mac != ""){ //get rid of reassociations 
             echo"\nAssociation found - checking database… mac = $mac\n"; 



             $result = mysql_query("SELECT * FROM mactable WHERE `mac` = '$mac'") or die("Error: " . mysql_error()); 
             $num_rows = mysql_num_rows($result); 

             if ($num_rows == "0") { 
               $result = mysql_query("INSERT INTO mactable VALUES ('$mac', now(), '', '')") or die("Error: " . mysql_error()); 
               sendsms("New device detected on home network. MAC address $mac"); 
             } else { 

               while ($row = mysql_fetch_array($result, MYSQL_NUM)) { 
                 if ($row[3] != "N"){ 
                   echo"Device detected on home network $mac ($row[2])\n\n"; 
                   if ($row[2] == "") { 
                     sendsms("Device detected on home network: $mac"); 
                   } else { 
                     sendsms("Device detected on home network: $row[2]"); 
                   }  

                 } 

               $result = mysql_query("UPDATE mactable SET lastseen = now() WHERE mac = '$mac'") or die("Error: " . mysql_error()); 

               } 

             } 
           } 
           mysql_close($db); 
     } 



     next($queue); 
     unset($job,$queue[$jobkey]);   



    } else { 
     echo 'no jobs to do - waiting...', PHP_EOL; 
     stream_set_blocking($pipe,true); 
    } 

} 

?>

不知道爲什麼會有人有一段代碼，並想知道它是從哪裏來的，而且它的目的是什麼，但代碼是從Twilio.php在這個文件中的服務文件夾：https://github.com/twilio/twilio-php/archive/master.zip

這是一個Twilio PHP庫，允許您在PHP中使用Twilio服務。 Twilio是一個提供可用於應用程序和網站等通信服務器的網站。你基本上可以用Twilio製作你自己的Skype版本。我希望這可以回答你的問題...
