最近在php下做關(guān)于Socket通訊的相關(guān)內(nèi)容，發(fā)現(xiàn)網(wǎng)絡(luò)上好多人在了解如何進(jìn)行16進(jìn)制收發(fā)，研究了下，代碼如下，歡迎拍磚。

復(fù)制代碼 代碼如下:

<?php
        $sendStr = '30 32 30 34 03 30 33';  // 16進(jìn)制數(shù)據(jù)

        $sendStrArray = str_split(str_replace(' ', '', $sendStr), 2);  // 將16進(jìn)制數(shù)據(jù)轉(zhuǎn)換成兩個(gè)一組的數(shù)組

        $socket = socket_create(AF_INET, SOCK_STREAM, getprotobyname("tcp"));  // 創(chuàng)建Socket

        if (socket_connect($socket, "192.168.1.100", 8080)) {  //連接
            for ($j = 0; $j < count($sendStrArray); $j++) {
                socket_write($socket, chr(hexdec($sendStrArray[$j])));  // 逐組數(shù)據(jù)發(fā)送
            }

            $receiveStr = "";
            $receiveStr = socket_read($socket, 1024, PHP_BINARY_READ);  // 采用2進(jìn)制方式接收數(shù)據(jù)
            $receiveStrHex = bin2hex($receiveStr);  // 將2進(jìn)制數(shù)據(jù)轉(zhuǎn)換成16進(jìn)制

            echo "client:" . $receiveStrHex;
        }
        socket_close($socket);  // 關(guān)閉Socket
        ?>
