我尝试通过按下按钮将png图像从JavaScript传递到PHP页面.但它返回一个错误,指出"Request-URI太大".以下是我的代码:

myJavaScript.js

                var w = window.open(); 
                var dom = w.document;
                var a = canvas[0].toDataURL("image/png"); 
                dom.write('< input type="button" value="Submit" onclick="location.href=\'result.php?a=' + a + '\'" ></input>');  

result.php

               <?php

                $aImg= $_GET["a"];

                $to = "abc@hotmail.com";
                $subject = "Sending an image to email";
                $body = '<img src="' .$aImg. '" alt="This is an image" />';
               if (mail($to, $subject, $body)) 
                              {   
                       echo("Message successfully sent!");  
                               } 
                 else {   
                   echo("Message delivery failed...");
                      }  
              ?>

但是,它返回"请求的URL的长度超过此服务器的容量限制".

是否有内置函数或API可用于转换月份名称,如FEB,2月到月号02？

我从视图传递到控制器.
