Tips for PHP uploading and saving to a folder

This time I will bring you the skills of PHP uploading and saving to a folder. What are the precautions for PHP uploading and saving to a folder? The following is a practical case, let's take a look.

I encountered such trouble recently. The error code returned when the temporary folder cannot be found is 6

Cause of error:

1.

Configuration file No temporary folder is set

2. No temporary folder or the upper-level folder does not have corresponding permissions

Processing Method:

Find the PHP configuration file PHP.ini and find the following code

;upload_tmp_dir =

Change to:

upload_tmp_dir = "C:/Windows/Temp"  //后面的文件夹路径根据您的系统来设置

If the permissions are not enough, you can add corresponding permissions to the files according to different operating systems

Other knowledge:

$_FILES[ 'file']['error']

The value is 0, no error occurs,

File upload is successful.

The value is 1, and the uploaded file exceeds the value of the upload_max_

filesize option in PHP.ini.

The value is 2, and the size of the uploaded file exceeds the value specified by the MAX_FILE_SIZE option in

HTML form.

The value is 3, and only part of the file is uploaded.

The value is 4 and no files were uploaded.

The value is 6 and the temporary folder cannot be found. PHP4.3.10 and PHP5.0.3 introduced.

The value is 7, file writing failed. PHP5.1.0 introduced.

If you see the error, it should be that the temporary folder does not have write permission or does not exist
