Yordamsal kullanım

mysqli_stmt_bind_param ( mysqli_stmt $stmt , string $types , mixed &$var1 [, mixed &$... ] ) : bool

Bind variables for the parameter markers in the SQL statement that was passed to mysqli_prepare().

Bilginize:

If data size of a variable exceeds max. allowed packet size (max_allowed_packet), you have to specify b in types and use mysqli_stmt_send_long_data() to send the data in packets.

Bilginize:

Care must be taken when using mysqli_stmt_bind_param() in conjunction with call_user_func_array(). Note that mysqli_stmt_bind_param() requires parameters to be passed by reference, whereas call_user_func_array() can accept as a parameter a list of variables that can represent references or values.
