How to implement URL Chinese transcoding in ThinkPHP
It is a very common requirement to use Chinese characters in URLs. For example, in forums, the title of a post is often in Chinese, and it needs to be used as part of the URL to generate the page address. However, due to historical reasons and some protocol restrictions, only those characters that exist in the ASCII code table can be used in the URL. Therefore, we need a way to convert Chinese characters into URL-safe characters so that we can use them to generate URL addresses. A common transcoding method is to use the urlencode function. This function converts Chinese characters into a special hexadecimal encoding to avoid conflicts in URLs. In ThinkPHP, we can use the url function for URL encoding. For example: $url

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 drive. Sometimes network transfers can cause unexpected file corruption. Even if the file has been saved locally, it may be damaged in an invisible way. 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. Finally, if the first two methods do not work, it means thinkphp has failed when saving network images.
