PHP PDO bindParam/bindValue Multiple times [duplicate]

Answer 1

Theoretical you could turn on emulation of prepared statements.

You must include a unique parameter marker for each value you wish to pass in to the statement when you call PDOStatement::execute(). You cannot use a named parameter marker of the same name more than once in a prepared statement, unless emulation mode is on.

Answer 2

I don't know too much about MsSQL to be honest, but I am quite sure there is some equivalent to User Defined Variables in MySQL. You could use those instead of parameters like I described in this answer:

Answer 3

Just turn emulation on, changing this setting from false to true:

$conn->setAttribute(PDO::ATTR_EMULATE_PREPARES, true);
