Question about Mysql_real_escape_string being self escaped after being inserted.


Recommended Posts

So I was under the assumption that when using mysql_real_escape_string() to escape user input data, that while its the database, thing like  say  It's  would be stored in the mysql DB as  it\'s.


It kind of threw me whether it was working or not.  IN the database the input was not escaped, but doing an echo.


$var = "'''''''''''''";
$var = mysql_real_escape_string($var);
echo $var;



Would print




But in the database it would be




So the question is. Is that how mysql_real_escape_string works? So the data in the database won't be escaped? It unescapes in the database? While that saves some trouble when retrieving the data.
