You need to pay attention to the php.ini file when uploading files
Before formally explaining the upload in this chapter, the first thing we need to pay attention to is the php.ini file.
This is our first introduction to how to modify the php.ini file. If your configuration items are inconsistent with what we said, please pay attention to the modification.
Let’s understand each configuration item.
Let’s take a look at how to modify php.ini.

In addition, you need to pay attention to the script execution time. max_execution_time, the unit of this parameter is seconds.This parameter is to set the maximum execution time of the script.
