Official ZPE/YASS documentationfile_put_contents
file_put_contents (string file[, boolean append], string contents1[, string contents2, string contents3, ..., string contentsN]) ⇒ string
Writes an infinite amount of parameters to a text file. You can append text on the end by inserting the boolean append before writing the file.
If you choose to do append and wish to write a boolean
value to the file, the suggestion is that you should use
file_put_contents("filename.txt", "", true)
as the second parameter will not be recognised as append boolean this way.
Prior to version 1.7.6 this method was called file_write. It was renamed as the file_write method was removed.
