What are the potential issues when transitioning from mssql() to sqlsrv() in PHP?

One potential issue when transitioning from mssql() to sqlsrv() in PHP is that the functions and syntax are different, so you may encounter errors or unexpected behavior in your code. To solve this, you will need to update your SQL queries and connection code to use the sqlsrv functions and follow the correct syntax.

// Old mssql connection code
$conn = mssql_connect($server, $username, $password);

// New sqlsrv connection code
$conn = sqlsrv_connect($server, array("UID" => $username, "PWD" => $password));
