    小编给大家分享一下php二进制转换为字符串的案例,相信大部分人都还不怎么了解,因此分享这篇文章给大家参考一下,希望大家阅读完这篇文章后大有收获,下面让我们一起去了解一下吧!php二进制转换为字符串的方法:首先创建一个PHP示例文件;然后通过BinToStr方法将二进制转换成字符串;最后通过echo输出转换结果即可。

    php二进制与字符串之间的相互转换<?php

    header("Content-type: text/html; charset=utf-8");

    /**

    * 将字符串转换成二进制

    * @param type $str

    * @return type

    */

    function StrToBin($str){

    //1.列出每个字符

    $arr = preg_split('/(?

    //2.unpack字符

    foreach($arr as &$v){

    $temp = unpack('H*', $v); $v = base_convert($temp[1], 16, 2);

    unset($temp);

    }

    return join(' ',$arr);

    }

    /**

    * 讲二进制转换成字符串

    * @param type $str

    * @return type

    */

    function BinToStr($str){

    $arr = explode(' ', $str);

    foreach($arr as &$v){

    $v = pack("H".strlen(base_convert($v, 2, 16)), base_convert($v, 2, 16));

    }

    return join('', $arr);

    }

    echo StrToBin("php二次开发:www.php2.cc");;

    echo '
    ';

    echo BinToStr("1110000 1101000 1110000 111001001011101010001100 111001101010110010100001 111001011011110010000000 111001011000111110010001 111011111011110010011010 1110111 1110111 1110111 101110 1110000 1101000 1110000 110010 101110 1100011 1100011");

    以上是php二进制转换为字符串的案例的所有内容,感谢各位的阅读!相信大家都有了一定的了解,希望分享的内容对大家有所帮助,如果还想学习更多知识,欢迎关注亿速云行业资讯频道!

    程序员的一天

    人闲太久,努力一下就以为是在拼命。

    一、前言

    python中,没有"0-1"形式的二进制类型,但我们依然可以存储二进制类型的数据。

    利用字符串(string)类型,可以存储二进制数据。即:将二进制数据以字符串的形式存储。

    下面分享一种字符串和二进制串互相转换的具体实现方法。

    二、代码

    """

    二进制、字符串转换

    """

    def str_2_bin(str):

    """

    字符串转换为二进制

    """

    return ' '.join([bin(ord(c)).replace('0b', '') for c in str])

    def bin_2_str(bin):

    """

    二进制转换为字符串

    """

    return ''.join([chr(i) for i in [int(b, 2) for b in bin.split(' ')]])

    if __name__ == '__main__':

    my_str = '欢迎关注个人公众号:【程序员的一天】'

    my_bin = str_2_bin(my_str)

    print(f'原始字符串示例:"{my_str}"')

    print(f'字符串变二进制:{my_bin}')

    my_str = bin_2_str(my_bin)

    print(f'二进制变字符串:"{my_str}"')

    运行结果:

    原始字符串示例:"欢迎关注个人公众号:【程序员的一天】"

    字符串变二进制:110101100100010 1000111111001110 101000101110011 110110011101000 100111000101010 100111010111010 101000101101100 100111100010111 101001111110111 111010 11000000010000 111101000001011 101111010001111 101010001011000 111011010000100 100111000000000 101100100101001 11000000010001

    二进制变字符串:"欢迎关注个人公众号:【程序员的一天】"

    I have binary data in a file that I can read into a byte array and process with no problem. Now I need to send parts of the data over a network connection as elements in an XML document. My problem is that when I convert the data from an array of bytes to a String and back to an array of bytes, the data is getting corrupted. I've tested this on one machine to isolate the problem to the String conversion, so I now know that it isn't getting corrupted by the XML parser or the network transport.

    What I've got right now is

    byte[] buffer = ...; // read from file

    // a few lines that prove I can process the data successfully

    String element = new String(buffer);

    byte[] newBuffer = element.getBytes();

    // a few lines that try to process newBuffer and fail because it is not the same data anymore

    Does anyone know how to convert binary to String and back without data loss?

    Answered: Thanks Sam. I feel like an idiot. I had this answered yesterday because my SAX parser was complaining. For some reason when I ran into this seemingly separate issue, it didn't occur to me that it was a new symptom of the same problem.

    EDIT: Just for the sake of completeness, I used the Base64 class from the Apache Commons Codec package to solve this problem.

    解决方案

    If you encode it in base64, this will turn any data into ascii safe text, but base64 encoded data is larger than the orignal data
