时间:2022-09-23 22:29:21

代码如下:


<?php 
global $PHP_SELF; 
//echo $PHP_SELF; 
$t1=$_POST['textfield1']; 
$t2=$_POST['textfield2']; 
$t3=$_POST['textfield3']; 
$t4=$_POST['textfield4']; 
// 汉字--区位码 
if($t1!=""){ 
$t2= sprintf("%02d%02d",ord($t1[0])-160,ord($t1[1])-160); 
//echo $t2; 

// 区位码--汉字 
if($t3!=""){ 
$t4 = chr(substr($t3,0,2)+160).chr(substr($t3,2,2)+160); 
//echo $t4; 

?>
