2. Use the <img src="/static/imghwm/default1.png" data-src="/images/logo.png" class="lazy" alt="How to output pictures in thinkphp" > tag in HTML to call the image. The code is as follows:

<img  src="/static/imghwm/default1.png" data-src="/images/logo.png" class="lazy" alt="How to output pictures in thinkphp" >

Sometimes the image path we need to output in thinkphp is dynamic. For example, we need to store the image path in the database, and then output different images based on the corresponding data. picture. At this time, we can use the following method to achieve dynamic path output pictures.

1. First, add an image field in the database to store the path of the image.

<img  src="/static/imghwm/default1.png" data-src="<?php echo url($imagePath); ?>" class="lazy" alt="How to output pictures in thinkphp" >

Among them, $imagePath represents the image path stored in the data table, and the url() method will automatically convert the path into the root directory of the website. relative path.

3. After completion, save and refresh the page, and you will be able to output images with dynamic paths.
