php - How much important is it to develop different database specific escaping mechanisms for different projects? -

-

as know, magic quotes in php deprecated, done discourage relying on feature preventing sql injection , encourage developers develop database specific escaping mechanisms.[source: php.net] neccessary?

if yes,

why? why can't use functions mysql_real_escape_string(), addslashes() , stripslashes() achieve same thing instead of developing different escaping mechanisms?

an answer example appreciated. thanks

mysql_real_escape_string() database specific escaping mechanism :)

if choosing database layer new project, sure take @ pdo prepared statements automatically take care of necessary escaping.
