I never said I wanted to save \h as an escape character.
I want to save the string 'H\hi' as is, (as used in the date() function 
for example).

As per my original post, this is what the doc suggests.

http://php.net/manual/en/function.mysql-real-escape-string.php

"If magic_quotes_gpc is enabled, first apply stripslashes() to the data. 
Using this function on data which has already been escaped will escape 
the data twice."

As indicated in my previous post this is what the doc says.
Unless I misunderstood the doc.

That's beside the point, but I agree.
