What to do if the php unlink function reports an error

The reason why the unlink() function reported an error: The specified file to be deleted does not exist. Solution: Add an error suppressor "@" before the unlink() function, and the syntax is "@unlink($filename)". The "@" error suppressor can block some errors and warning messages caused by problems encountered during function execution.

The unlink() function is used to delete the specified file , but if you want to delete a file that does not exist, unlink() will report an error.

<?php
$to_link = &#39;C:\Users\Administrator\Desktop\cut.jpg&#39;;
unlink($to_link);
?>

If you want to block the error report of the unlink function, you can use the error suppressor "@" and add an error suppressor "@" before the unlink() function.

<?php
$to_link = &#39;C:\Users\Administrator\Desktop\cut.jpg&#39;;
@unlink($to_link);
?>

If you use @unlink(), no error will be reported.

Explanation: @Error suppressor

@ can shield some errors and warning messages caused by problems encountered during function execution, so that users cannot see the error messages of the program. In addition to a friendlier user interface, this is more important for security, because information such as the path to the error file is blocked.
