**toString: function toString() { [native code] }
*__proto__: Object

**__defineGetter__: function __defineGetter__() { [native code] }
**__defineSetter__: function __defineSetter__() { [native code] }
**__lookupGetter__: function …

我已经通过AJAX将一个base64编码的字符串发送到PHP并创建了一个图像资源imagecreatefromstring- 一切都很好.
