Converting PHP site from MySQL to SQL.

[ShootingBlanks]

I made a PHP site with a MySQL database that has people fill in a form and then it dumps the form data to a database.  Then there's pages that populate themselves with the database data.  There's more to it (user authentication, etc), but my main problem is this...

 

...my company wants to use the site, but they won't use MySQL - only MSSQL.  I have ZERO experience in MSSQL, so I need to convert all my pages.

 

I saw that most of the MySQL commands that start with "mysql_" have equivalents that start with "mssql_" (mysql_query and mssql_query, for example).  But there are many that do not (mysql_real_escape_string and mysql_error, for example)...

 

Am I in for a massive undertaking here, or should this all go relatively smoothly if I just change the "mysql"s to "mssql"?

 

Thanks!
