Is there any function in javascript-php that can obtain the full path of this file based on the file name? Or how does js obtain the full file path?

Example: {code...} example:

Use demo.txt to obtain the full path: C:/Users/ilovemosh/Desktop/demo.txt.

For example:

Use demo.txt to obtain the full path: C:/Users/ilovemosh/Desktop/demo.txt.

Your file must be in include_path. it is impossible for you to give an absolute path to a file name .. Not so powerful

Portal

Dirname (_ FILE __)
Obtain the absolute path of a file

Folder where the PHP file is currently executed_ DIR __AccordingDemo.txtThe relativity with the current PHP file is just to determine the file path.

Generally, you must first use a certain method (such as uploading) to obtain the file information.

In js, the plupload plug-in obtains the information of this file by uploading this file (but it is not necessarily where the file is successfully uploaded, but by obtaining the file object for calculation, all file path information can be obtained for php yii Framework uploads.
