<?php 
    $name = $_POST['image'];
     $entry = base64_decode($name);
     $image = imagecreatefromstring($entry);
     $directory = dirname(__FILE__).DIRECTORY_SEPARATOR."images/".DIRECTORY_SEPARATOR."index".$title.".jpeg";
     header ( 'Content-type:image/jpeg' );
     $imagetojpg=imagejpeg($image, $directory); 
     imagedestroy($image );      
     readfile ($directory);  
     exit ();
    ?>

这应该可以正常工作.image 是一个包含 base64 编码字符串的变量.

This should work fine.image is a variable which contain base64 encoded string.
