The suggestion to use addslashes() instead of a database specific escape string type function (e.g.
mysql_escape_string(), mysql_real_escape_string(), pg_escape_string()) directly conflicts with
information listed on the escape string function pages.
From the pg_escape_string manual:
"pg_escape_string() escapes string for text/char datatype. It returns escaped string for
PostgreSQL. Use of this function is recommended instead of addslashes()."
However, not every database has a built in escape string function (ie. there is no
mssql_escape_string() for MS SQL databases at this time), so using such databases require the use of
addslashes() to escape data.
I should also note that if you have your magic quotes turned on, you shouldn't need to use
addslashes(), and doing so will add extra slashes to your text.
