This article mainly introduces how Symfony2 uses a third-party library Upload to Upload images, and analyzes in detail the steps and skills of Symfony2 using a third-party library Upload based on the instance form, for more information about how to use the third-party library Upload to Upload images, see the example in this article. We will share this with you for your reference. The details are as follows:

We generally have the Avatar setting function in personal data of applications or websites. in this chapter, we use a third-party Upload Library in Symfony2 to create and Upload images.
