I\'m getting this message when I try to run a php script I have to use but did not write.
Deprecated: Function set_magic_quotes_runtime() is deprecated in /o
Check if it's on first. That should get rid of the warning and it'll ensure that if your code is run on older versions of PHP that magic quotes are indeed off.
Don't just remove that line of code as suggested by others unless you can be 100% sure that the code will never be run on anything before PHP 5.3.
get_magic_quotes_runtime is NOT deprecated in PHP 5.3.
