jQuery实现的对上传图片进行裁剪插件

<?php $aa=$_POST['pic']; define('UPLOAD_DIR', dirname(__FILE__).'/upload/'); //图片保存路径 $img = $aa; $img = str_replace('data:image/png;base64,', '', $img); $img = str_replace(' ', '+', $img); $data = base64_decode($img); $filename = date('YmdHis',time()) . '.jpg'; $file = UPLOAD_DIR . $filename; $success = file_put_contents($file, $data); exit ($success ? $filename: 'error'); ?>
