本文实例讲述了PHP实现36进制与10进制转换功能。分享给大家供大家参考，具体如下：
PHP;">
/**
* @desc im:十进制数转换成三十六机制数
* @param (int)$num 十进制数
* return 返回：三十六进制数
*/
function get_char($num) {
$num = intval($num);
if ($num <= 0)
return false;
$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');
$char = '';
do {
$key = ($num - 1) % 36;
$char= $charArr[$key] . $char;
$num = floor(($num - $key) / 36);
} while ($num > 0);
return $char;
}
/**
* @desc im:三十六进制数转换成十机制数
* @param (string)$char 三十六进制数
* return 返回：十进制数
*/
function get_num($char){
$array=array("0","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");
$len=strlen($char);
for($i=0;$i<$len;$i++){
$index=array_search($char[$i],$array);
$sum+=($index+1)*pow(36,$len-$i-1);
}
return $sum;
}
使用实例:
PHP;">
echo "get_char:".get_char(514549)."
"; echo "get_num:".get_num('A0ZZ')."
";
"; echo "get_num:".get_num('A0ZZ')."
";
PS：这里再为大家推荐几款计算与转换工具供大家参考使用：
