php unlink deletion problem

When deleting pictures

For example: unlink('abcdef.jpg');

This way you can delete it normally;

But the file name cannot be deleted when it is read from the database

fn=$rs['abc'];

unlink($fn);

It cannot be deleted. Have any experts encountered such a situation?

Prompt message:

Warning: unlink(user_logo/d4d84f383714d5f3.jpg) [function.unlink]: No such file or directory in

　------Solution--------------------

Didn’t he make it very clear?

　No such file or directory No such file or directory

　------Solution--------------------

Error message file does not exist

It should be that the path is wrong

　------Solution--------------------

First check whether the file exists and then delete it

The warnings are that the file or directory does not exist

　if(file_exists($fn)){

unlink($fn);

　}

　------Solution--------------------

Look at your user_logo/ directory to see if this file exists in this directory

If not, then delete it. If yes, delete it. Add a judgment

　if(file_exists($fn)){//The file exists

//todo delete

　}
