file_get_contents functions in my theme to write a small text on a text file stored in the temp folder.
But the theme-check plugin gives me following warnings:
WARNING: file_get_contents was found in the file xxx.php possible file operations.
WARNING: file_put_contents was found in the file xxx.php possible file operations.
I could not find any alternative wordpress function. Can you please suggest how can I get rid of above warnings?
