Renaming a file in php with the date at the end

Question

I'm trying to rename a file with a specific date attached to the end of the file name. For example: vertices_dly_jrnl_automation_25_June_2013.csv.

The date must be 1 day prior to the current date.

This is the error I'm receiving: Invalid Argument

Answer 1

You need to escape your backslashes, so use \\ instead of \ everywhere
