How to solve the problem that thinkphp saves network pictures but does not display them

First, check whether the saved image has been completely saved to the local hard disk. Even if the file has been saved locally, network transmission can sometimes cause the file to be corrupted invisibly. So first you need to confirm whether the file itself is intact.

Secondly, check whether the saved image is saved in the correct format. When using thinkphp to save network images, they are saved in .jpg format by default. If you want to save images in other formats, you need to make corresponding adjustments. If the format is incorrect, the saved image will not be displayed properly.

If the first two methods are not feasible, it may be because thinkphp is invalid when saving network images. At this point, you can consider using other frameworks or using native PHP implementation. The following code can easily implement the native PHP implementation of saving images

// 获取远程图片数据  
$data = file_get_contents($url);  

// 打开本地文件并写入数据  
$fp = fopen($path, 'w');  
fwrite($fp, $data);  
fclose($fp);

It also makes use of some good foreign framework patterns, uses an object-oriented development structure, and is compatible with many tag libraries and other patterns. It can be more convenient and faster. Developing and deploying applications, not just enterprise-level applications of course, any PHP application development can benefit from the simplicity, compatibility and speed of thinkphp.
