PHP字符串到十六进制 [英] PHP string to hex
本文介绍了PHP字符串到十六进制的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个这样的字符串:
[0-9A-Za-z\ + / =] * $如何转换为以下形式:
pre> \133\x30\55\x39\101\x2d\132\x61\55\x7a\134\x2b\ 57 \x3d\135\x2a
这有什么功能吗?
解决方案
function strtohex($ string)
{
$ string = str_split ($ string);
foreach($ string as& $ char)
$ char =\x.dechex(ord($ char));
return implode('',$ string);
}
print strtohex([0-9A-Za-z\ + / =] *);
上述代码会给你
\x5b\x30\x2d\x39\x41\x2d\x5a\x61\x2d\x7a\x5c\x2b\x2f\ x3d \x5d\x2a
我知道它看起来不像输出expect,但是似乎不是字符串到十六进制。
I have a string like that:
[0-9A-Za-z\+/=]*
How can I converted in the following form:
"\133\x30\55\x39\101\x2d\132\x61\55\x7a\134\x2b\57\x3d\135\x2a"
Is there any function for that ?
解决方案
function strtohex($string)
{
$string = str_split($string);
foreach($string as &$char)
$char = "\x".dechex(ord($char));
return implode('',$string);
}
print strtohex("[0-9A-Za-z\+/=]*");
The above code will give you
\x5b\x30\x2d\x39\x41\x2d\x5a\x61\x2d\x7a\x5c\x2b\x2f\x3d\x5d\x2a
I'm aware that it doesn't look like the output you expect, but that doesn't seem to be string to hex at all.
