PHP - File Delete
You know how to create a file. You know how to open a file in an assortment of different ways. You even know how to read and write data from a file!Now it's time to learn how to destroy (delete) files. In PHP you delete files by calling the unlink function.
PHP - File Unlink
When you view the contents of a directory you can see all the files that exist in that directory because the operating system or application that you are using displays a list of filenames. You can think of these filenames as links that join the files to the directory you are currently viewing.If you unlink a file, you are effectively causing the system to forget about it or delete it!
Before you can delete (unlink) a file, you must first be sure that it is not open in your program. Use the fclose function to close down an open file.
PHP - Unlink Function
Remember from the PHP File Create lesson that we created a file named testFile.txt.PHP Code:
$myFile = "testFile.txt"; $fh = fopen($myFile, 'w') or die("can't open file"); fclose($fh);
PHP Code:
$myFile = "testFile.txt"; unlink($myFile);
