本文實例講述了php實現(xiàn)36進制與10進制轉(zhuǎn)換功能。分享給大家供大家參考，具體如下：

1. /** 
2.  * @desc im:十進制數(shù)轉(zhuǎn)換成三十六機制數(shù) 
3.  * @param (int)$num 十進制數(shù) 
4.  * return 返回：三十六進制數(shù) 
5. */ 
6. functionget_char($num) { 
7.   $num=intval($num); 
8.   if($num<= 0) 
9.     returnfalse; 
10.   $charArr=array("0","1","2","3","4","5","6","7","8","9",'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'); 
11.   $char='' 
12.   do{ 
13.     $key= ($num- 1) % 36; 
14.     $char=$charArr[$key] .$char; 
15.     $num=floor(($num-$key) / 36); 
16.   }while($num> 0); 
17.   return$char; 
18. } 
19. /** 
20.  * @desc im:三十六進制數(shù)轉(zhuǎn)換成十機制數(shù) 
21.  * @param (string)$char 三十六進制數(shù) 
22.  * return 返回：十進制數(shù) 
23.  */ 
24. functionget_num($char){ 
25.   $array=array("0","1","2","3","4","5","6","7","8","9","A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"); 
26.   $len=strlen($char); 
27.   for($i=0;$i<$len;$i++){ 
28.     $index=array_search($char[$i],$array); 
29.     $sum+=($index+1)*pow(36,$len-$i-1); 
30.   } 
31.   return$sum; 
32. } 

使用實例:

1. echo"get_char:".get_char(514549)."<br>"; 
2. echo"get_num:".get_num('A0ZZ')."<br>";
