二进制字符串到数组到HEX颜色

尝试从以二进制格式存储它们的程序中导入一些颜色托盘。我需要将它们拆分并转换为十六进制。看到这个工具后，我认为这不会太难：https://www.binaryhexconverter.com/binary-to-hex-converter，但我没有得到我预期的结果。

$new_arr = array_map('trim', explode(',', trim($color, '[]')));

$arr = array_chunk($new_arr, 3);

foreach($arr as $bingroup){
    print("<div style='position:absolute;height:20px;width:20px;background:#");
    foreach($bingroup as $binitem){

    $hex = bin2hex ($binitem);
    print($hex);
    }
    print("'></div>");
}

因此，我导入字符串，修剪，将其分解为数组，将它们分组为3个组，然后使用bin2hex() - ＆gt;使用几个foreach循环遍历它。简单吧？为什么我得到

<div style="position:absolute;height:20px;width:20px;background:#303030303130313031313130313131313131303030303031"></div>

2 个答案:

答案 0 :(得分：2)

这是因为您实际上没有将二进制数转换为十六进制，bin2hex()期望。您正在尝试将二进制数的字符串表示转换为十六进制。

ASCII字符＆＃34; 0＆＃34;是＆＃34; 30＆＃34;十六进制，字符＆＃34; 1＆＃34;是＆＃34; 31＆＃34;十六进制。所以转换字符串＆＃34; 00001010＆＃34;使用binhex()到十六进制将返回字符串＆＃34; 3030303031303130＆＃34;。

获得所需内容的解决方法是首先将字符串转换为十进制（有趣的是，bindec()支持字符串），然后从十进制转换为十六进制：

echo dechex(bindec("00001010"));
// "a"
// -> 00001010 in binary = 10 in decimal = "a" in hexadecimal

所以你需要改变这一行：

// $hex = bin2hex ($binitem);
$hex = dechex(bindec($binitem));

CSS支持所有颜色的单字符颜色代码（＆＃34;＃abc＆＃34;）或所有颜色的双倍（＆＃34;＃aabbcc＆＃34;），但不是两者的混合，所以你可能还需要添加额外的检查以确保颜色代码＆lt; 16将输出为＆＃34; 0a＆＃34;而不只是＆＃34; a＆＃34;。

您可以使用sprintf()。这将十进制（转换后）格式化为十六进制，填充0到2个字符。

$hex = sprintf('%02x', bindec($binitem));
