我怎样才能打破这个PHP while循环？

Question

我是一名PHP新手，在一个IRC bot上工作，它加入一个频道，发送一条消息，然后退出。

除了发送$ message之外，一切都在脚本中工作（第6行），我不明白如何退出无限循环。

// Open Internet connection 
$socket = fsockopen("$server", $port); 
fputs($socket,"USER $nick $nick $nick $nick :$nick\n"); 
fputs($socket,"NICK $nick\n"); 
fputs($socket,"JOIN ".$chan."\n"); 
fputs($socket, "PRIVMSG ".$chan." :$message1\n"); 


// Begin while loop 
while(1) { 
    while($data = fgets($socket)) { 
     echo nl2br($data); 
     flush(); 

     $ex = explode(' ', $data); 
     $channel = $ex[2]; 
     $nicka = explode('@', $ex[0]); 
     $nickb = explode('!', $nicka[0]); 
     $nickc = explode(':', $nickb[0]); 

     // $host = $nicka[1]; 
     $nick = $nickc[1]; 
     if($ex == "PING"){ 
      fputs($socket, "PONG ".$ex[1]."\n"); 
     } 

     $args = NULL; for ($i = 4; $i < count($ex); $i++) { $args .= $ex[$i] . ' '; } 

    } 
} 

Answer 1

你需要只有1 while循环，当条件为真时将停止。

您可以阅读http://php.net/manual/en/control-structures.while.php

while(1) {  // <-- Remove the infinite loop 
    while($data = fgets($socket)) { 

Answer 2

如果你要离开插座打开你所需要的时间。解决此问题的最佳方法是回拨。但是如果你只想打破这些时间。

// Open Internet connection 
$socket = fsockopen("$server", $port); 
fputs($socket,"USER $nick $nick $nick $nick :$nick\n"); 
fputs($socket,"NICK $nick\n"); 
fputs($socket,"JOIN ".$chan."\n"); 
fputs($socket, "PRIVMSG ".$chan." :$message1\n"); 


// Begin while loop 
all_data_received = False 
while(1) { 
while($data = fgets($socket)) { 
    echo nl2br($data); 
    flush(); 

    $ex = explode(' ', $data); 
    $channel = $ex[2]; 
    $nicka = explode('@', $ex[0]); 
    $nickb = explode('!', $nicka[0]); 
    $nickc = explode(':', $nickb[0]); 

    // $host = $nicka[1]; 
    $nick = $nickc[1]; 
    if($ex == "PING"){ 
     fputs($socket, "PONG ".$ex[1]."\n"); 
    } 

    $args = NULL; for ($i = 4; $i < count($ex); $i++) { $args .= $ex[$i] . ' '; 

    all_data_received = True //or some other conditions 

    } 

    if (all_data_received == True){ 
     break; 
     } 

}
