如何在没有ord()的PHP中将字符串转换为ASCII值?

问题描述

我正在寻找一个将字符串'Hello'world转换为php中的ASCII值的方法.但是我不想使用ord().还有其他不使用ord()来打印ascii值的解决方案吗?

I am looking to convert a string say 'Hello' world to its ASCII value in php.But I don't want to use ord(). Are there any other solutions for printing ascii value without using ord()?

推荐答案

unpack()

使用格式 C*返回您从ord()获得的一切.

Use the format C* to return everything as what you'd get from ord().

print_r(unpack("C*", "Hello world"));

Array
(
    [1] => 72
    [2] => 101
    [3] => 108
    [4] => 108
    [5] => 111
    [6] => 32
    [7] => 119
    [8] => 111
    [9] => 114
    [10] => 108
    [11] => 100
)
