addslashes
(PHP 4, PHP 5)
addslashes — Quote string with slashes
Description
string addslashes
( string $str
)
An example use of addslashes() is when you're
entering data into a database. For example, to insert the name
O'reilly into a database, you will need to escape
it. Most databases do this with a \ which would
mean O\'reilly. This would only be to get the data
into the database, the extra \ will not be inserted.
Having the PHP directive
magic_quotes_sybase set to on will mean
' is instead escaped with another
'.
The PHP directive
magic_quotes_gpc is on by default, and it
essentially runs addslashes() on all GET, POST,
and COOKIE data. Do not use addslashes() on
strings that have already been escaped with
magic_quotes_gpc as you'll
then do double escaping. The function
get_magic_quotes_gpc() may come in handy for
checking this.
Parameters

str
-
The string to be escaped.
