How to solve the problem that the picture part of php call is not displayed

With the development of the Internet, the importance of websites has become more and more obvious, and it is a very common operation to use PHP language to call images in website production. However, sometimes you may encounter such a problem: when PHP calls images, some images do not display properly. So, what is the reason for this problem? Let’s analyze it below.

1. The file path is incorrect

When calling an image, you first need to ensure that the file path is correct. If the path is incorrect, the image will not load properly. For example, if your picture is stored in the img directory, but when you call the picture, the path is written as imges, then the call will be unsuccessful.

2. The file name is incorrect

In PHP code, relative paths or absolute paths are usually used to reference images. If the file name is incorrect, it will also cause the image to not be displayed normally. For example, if your picture file name is pic1.jpg, but you spell it as pic1.jpg in the code, then the picture will not be found.

3. The file type is incorrect

When PHP calls an image, you need to specify the image type. Common ones include .jpg, .png, .gif, etc. If the file type is incorrect, the image will not display properly. For example, if you write the name of a picture in .gif format as pic1.jpg, it will not be displayed.

4. The file does not exist

When the picture that needs to be called does not exist, it will also cause the picture to not be displayed normally. This situation is relatively common. It may be that the picture has been deleted or moved.

5. File permission issues

In PHP, some directories and files need to have corresponding permissions set before they can be read and accessed. If the permissions are not set correctly, it will also cause the image to fail. normal display. The permissions of directories and files can be modified through FTP tools, usually set to 755 or 777.

The above situations are five common causes of problems when PHP calls images. If you encounter these problems, you can troubleshoot and solve them according to the situation. At the same time, when developing, it is recommended to store the code that calls the image and the image in the same directory, so that management and debugging can be more convenient.
