PHP套接字错误在Linux上被拒绝

我在Linux 2.6.34上安装了php 5.4.13。

我有一个简单的客户端/服务器页面使用套接字，但它没有工作。

给出permission denied error

if (false == ($socket = socket_create(AF_INET, SOCK_STREAM, 0)))  // create socket 
{
   $stringData= date("D M d, Y g:i A"). " socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "<br>";
   echo $stringData;
}
else
{
    $timeout = array('sec'=>5,'usec'=>500000);
    socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,$timeout);
    if(false==($result = socket_connect($socket, $host, $port)))
    {
        $stringData= date("D M d, Y g:i A"). " socket_connect() failed: reason: " . socket_strerror(socket_last_error()) . "<br>";
        echo $stringData;
        socket_close($socket);
    }
    else
    {
        $stringData= date("D M d, Y g:i A"). " Socket connected succefully <br>";
        echo $stringData;
        if(false==(socket_write($socket, $command, strlen($command))))
        {
            $stringData= date("D M d, Y g:i A"). " socket_write() failed: reason: " . socket_strerror(socket_last_error()) . "<br>";
            echo $stringData;
            socket_close($socket);
        }
        else
        {
            if(false===($cmd = socket_read ($socket, 65536)))
            {
                //10060 for windows and 11 for linux
              if(10060!=socket_last_error() && 11!=socket_last_error())
              {
                $stringData= date("D M d, Y g:i A"). " socket_read() failed: reason: " . socket_strerror(socket_last_error()) . "<br>";
                echo $stringData;
                socket_close($socket);
              }
              switch(socket_select($r = array($socket), $w = array($socket), $f = array($socket), 5))
              {
                       case 2:
                               $refused=1;  
                               break;
              }
              if($refused==1)
              {
                $stringData= date("D M d, Y g:i A"). " socket_read() failed: reason: Connection Refused <br>";
                $ourFileHandle = fopen(SOCKET_LOG, 'a');
                echo $stringData;
                socket_close($socket);
              }
            }
            else
            {
                echo "<pre>".html_entity_decode(print_r($cmd,true))."</pre>";
            }
        }
    }
}

以上代码在命令提示符下工作正常，但当从任何浏览器打开页面时，它会给出错误Permission denied。

从终端运行php命令:/usr/local/rootfs/php5/bin/php /www/socket_client.php
