Question

Trying to delete a file, but it refuses to be deleted. I’ve tried the following which has if statement that check the file already exists & other .db file is blank. Path is correct, setting it to 666 so can delete, then unlink, then writing the file back with the word “open” in it.

if(file_exists("results_files/linktracker/linktrackerlock.txt") && file_get_contents("results_files/linktracker/linktracker.db") == "") {  // check for reset condition, ie. db file wiped
    chmod("results_files/linktracker/linktrackerlock.txt", 0666);
    unlink("results_files/linktracker/linktrackerlock.txt");
    file_put_contents("results_files/linktracker/linktrackerlock.txt", "open");
}

Answer 1

chown will change the ownership of the file passed as first argument, you are probably better off using chmod (which is used to change permissions).
