Question

我想使用数字和数字（即w3b）将数字（即19455）更改为更短的内容，因此例如数字19455被w3b取代。当我输入w3b时，我希望能够取回那个号码。是否有我可以使用的现成功能，或者我必须自己构建它？

Answer 1

使用base_convert php函数：

示例：

$myNumInDecimal = "1234567787";
$myNumInBase36 = base_convert($myNumInDecimal, 10, 36);

这会给你：

但请注意，往返基地的时间应介于2..36之间。

我希望这会......

     <?
     # MAKE STRING INTO ARRAY TO FOR NUMBERS 0-9
   $numbers = array();
   for($counter =0; $counter <= 10; $counter++) {
       $numbers[$counter] = $counter;
    }


                 # FUNCTION TO CHANGE NUMBER INTO LETTERS
     function change_to_letters($string) {
    global $numbers;
  $replacements = array("a","b","c","d","e","f","g","h","i","j");
     $string = str_replace($numbers, $replacements, $string);
  return $string;
 }
     if(isset($_POST['submit'])){
    echo 'I changed '.$_POST['string'].' to this:<div style="border: 1px solid          #666;background-  color:                                                                #E6FAD9;width:200px;padding:5px;">'.change_to_letters($_POST['string']).'</div>';
          }

          ?>
