如何在php中将十六进制值转换为字母字符串

Question

有没有办法获取特定十六进制值的字母字符串？

Answer 1

You can use hex2bin to convert hex:

$string = hex2bin($hex);

If you want to remove any non-alpha character from $string you can use a regular expression to remove anything that's not az or AZ:

$alpha_only = preg_replace("/[^a-zA-Z]+/", '', $string);
