作者:admin 日期:2015-11-11
PHP代码
- header('Content-type:text/html;charset=utf-8');
- //读取图片文件,转换成base64编码格式
- $image_file = './4296762_165319032930_2.jpg';
- $image_info = getimagesize($image_file);
- $base64_image_content = "data:{$image_info['mime']};base64," . chunk_split(base64_encode(file_get_contents($image_file)));
- //保存base64字符串为图片
- //匹配出图片的格式
- if (preg_match('/^(data:\s*image\/(\w+);base64,)/', $base64_image_content, $result)){
- $type = $result[2];
- $new_file = "./test.{$type}";
- if (file_put_contents($new_file, base64_decode(str_replace($result[1], '', $base64_image_content)))){
- echo '新文件保存成功:', $new_file;
- }
- }
<img src=
"<?php echo $base64_image_content;?>"
