This article mainly introduces the conversion function of UTF8 binary and plain text strings in PHP, involving operating techniques related to PHP binary and encoding conversion. Friends in need can refer to it

The details are as follows:


<?php
define("b", "<br>");
$a = "FE";
$a1 = "FF";
$s = 16;
$e = 2;
echo $s . "进制的" . $a . "表示为" . $e . "进制是" . base_convert($a, $s, $e) . b;
echo $s . "进制的" . $a1 . "表示为" . $e . "进制是" . base_convert($a1, $s, $e) . b;
$str = "计算机rr我们是谁?";
$strlen = strlen($str);
$n = 0;
echo $str.&#39;(二进制UTF-8表示):&#39;.b;
$str_bin=&#39;&#39;;
while ($n < $strlen)
{
  $t = ord($str[$n]);
  $stra=base_convert($t, 10, 2) ;
  if(strlen($stra)<8)
  {
    $stra="0".$stra;
  }
  $str_bin.=$stra;
  $n++;
}
echo $str_bin.b;//已经翻译为二进制了
$str_bin="1110100010101110101000011110011110101110100101111110011010011100101110100110000101110011111001101000100010010001111001001011101110101100111001101001100010101111111010001011000010000001111011111011110010011111"; //在此输入二进制,程序编码为明文输出
$chr=&#39;&#39;;
$str=&#39;&#39;;
for($i=0;$i<strlen($str_bin);$i++)
{
  $chr.=$str_bin[$i];
  if(($i+1)%8==0)
  {
    $str.=chr(base_convert($chr, 2, 10));
    $chr=NULL;
  }
}
echo $str;//二进制的UTF8原代码明文
?>


Running results:


16进制的FE表示为2进制是11111110
16进制的FF表示为2进制是11111111
计算机rr我们是谁?(二进制UTF-8表示):
1110100010101110101000011110011110101110100101111110011010011100101110100111001001110010111001101000100010010001111001001011101110101100111001101001100010101111111010001011000010000001111011111011110010011111
