This error message indicates that a file cannot be opened using the fopen function , this is due to permissions or not being able to find the file.

The following causes occur:

• The file path is incorrect
• The file path is relative

A common error message is not using the absolute path to the file. This is easily solved by using the full path or using magic constants such as __DIR__

or dirname(__FILE__)
