如何从＆＃34; 0013D5011F46＆＃34;转换MAC地址？至＆＃34; 0.19.213.1.31.70＆＃34;用PHP？谢谢！

Answer 1

One-liner：

$mac = implode('.', array_map("hexdec", str_split("0013D5011F46", 2)));

说明：

$arr = str_split("0013D5011F46", 2);    // split the string into chunks of two characters
$arr = array_map("hexdec", $arr);       // convert every hex value to its decimal equivalent
$mac = implode('.', $arr);              // join array elements to string

有关参考，请参阅str_split()，array_map()，hexdec()和implode()

Answer 2

试试这个：

$str = '0013D5011F46';
$mac = implode('.', array_map('hexdec', str_split($str, 2)));

OR

$str = '00:13:D5:01:1F:46';
$hex = explode(':', $str);
$result = implode(array_map('hexdec', $hex), '.');
echo $result;

Answer 3

以下一种方式将其作为通用解决方案，能够处理任意长度的十六进制字符串：

<?php
    function doNext($s, $slen) {
        // String is even length here, exit if
        // no sections left.

        if ($slen == 0) {
            return;
        }

        // This is a section other than the first,
        // so prefix it with "." and output decimal.

        echo ".";
        echo hexdec(substr($s, 0, 2));

        // Do remainder of string.

        doNext(substr($s, 2), $slen - 2);
    }

    function doIt($s) {
        // Get length, exit if zero.

        $slen = strlen($s);
        if ($slen == 0) {
            return;
        }

        // Process forst section, one or two
        // characters depending on length.

        if (($slen % 2) != 0) {
            echo hexdec(substr($s, 0, 1));
            doNext(substr($s, 1), $slen - 1);
        } else {
            echo hexdec(substr($s, 0, 2));
            doNext(substr($s, 2), $slen - 2);
        }
    }

    // Here's the test case, feel free to expand.

    doIt("0013D5011F46");
?>

它基本上将字符串视为一个由两个十六进制数字组成的分组，处理前一个（如果字符串长度为奇数，则可能只有一个字符长），然后将其剥离并递归处理字符串的其余部分

对于第一个以外的每个部分，它输出.后跟十进制值。

Answer 4

$input = '0013D5011F46';

$output = implode(".", array_map( 'hexdec', explode( "\n", trim(chunk_split($input, 2)))));
