3. Find file uploads :(Modify upload switch restrictions)

Whether to allow file uploading via http switch, confirm file_uploads = on

4. Find upload_tmp_dir:(Modify upload temporary file restrictions)

The file is uploaded to the place where temporary files are stored on the server. If not specified, the system's default temporary folder will be used. If the system error prompts "xxx temporary directory xxx", you need to set a valid directory for this directory. If no error is reported, don't worry.

5. Find upload_max_filesize:(Modify upload size limit)

The maximum allowed upload file size, the default is 2m, Set this parameter to the value you need. It is recommended not to exceed the post_max_size value, because it is controlled by the post_max_size value (even if upload_max_filesize is set to 1g,

and post_max_size is only set to 2m, it is greater than 2m The file still cannot be uploaded because it is controlled by the post_max_size value)

6. If you want to upload a file larger than 8m, you also need to set the following parameters: (Modify upload time limit)

Find max_execution_time = 600; The maximum time value (seconds) for each php page to run, the default is 30 seconds
