PHP字符串转十六进制的方法:首先创建PHP文件;然后定义一个strToHex方法用于字符串转十六进制;最后在方法体内通过for循环语句、dechex函数以及strtoupper函数来实现转换即可。

PHP字符串怎么转十六进制

今天在做项目中,因为要调用别人网站的接口,结果需要对请求和返回的时间进行十六进制加密处理,于是在网上查了下资料谢了一个转换Demo做个记录。

如果在TP下使用可以将下面函数放到common.php中

 

一,加密函数

<?php
/**
*字符串转十六进制函数
*@pream string $str=&#39;abc&#39;;
*/
function strToHex($str){
$hex="";
for($i=0;$i<strlen($str);$i++)
$hex.=dechex(ord($str[$i]));
$hex=strtoupper($hex);
return $hex;
}
?>
Copy after login

二、解密函数

<?php
/**
*十六进制转字符串函数
*@pream string $hex=&#39;616263&#39;;
*/
function hexToStr($hex){
$str="";
for($i=0;$i<strlen($hex)-1;$i+=2)
$str.=chr(hexdec($hex[$i].$hex[$i+1]));
return $str;
}
?>
Copy after login

加密 解密 转换 函数使用Demo事例,这里为了方便写在了一个类中。

<?php
class Test{
/**
*字符串转十六进制函数
*@pream string $str=&#39;abc&#39;;
*/
public function strToHex($str){
$hex="";
for($i=0;$i<strlen($str);$i++)
$hex.=dechex(ord($str[$i]));
$hex=strtoupper($hex);
return $hex;
}
/**
*十六进制转字符串函数
*@pream string $hex=&#39;616263&#39;;
*/
public function hexToStr($hex){
$str="";
for($i=0;$i<strlen($hex)-1;$i+=2)
$str.=chr(hexdec($hex[$i].$hex[$i+1]));
return $str;
}
}
<span style="white-space:pre"> </span>//测试Demo效果
$test = new Test();
$str = &#39;要加密的内容sxfenglei&#39;;
$data = $test->strToHex($str);
echo &#39;加密内容:要加密的内容sxfenglei <br>&#39;.$data.&#39;<hr>&#39;;
$output = $test->hexToStr($data);
echo &#39;解密内容:E8A681E58AA0E5AF86E79A84E58685E5AEB9737866656E676C6569 <br>&#39;.$output;
?>
Copy after login

运行结果:

加密内容:要加密的内容sxfenglei

E8A681E58AA0E5AF86E79A84E58685E5AEB9737866656E676C6569
Copy after login
Copy after login

解密内容:

E8A681E58AA0E5AF86E79A84E58685E5AEB9737866656E676C6569
Copy after login
Copy after login

要加密的内容sxfenglei
