Microsoft Drivers for PHP for SQL Server version 2.0 and 3.0 |
sqlsrv_close |
Example See Also Send Feedback |
Closes the specified connection and releases associated resources.
Syntax
sqlsrv_close( resource $conn ) |
Parameters
$conn: The connection to be closed.
Return Value
The Boolean value true unless the function is called with an invalid parameter. If the function is called with an invalid parameter, false is returned.
Note |
---|
Null is a valid parameter for this function. This allows the function to be called multiple times in a script. For example, if you close a connection in an error condition and close it again at the end of the script, the second call to sqlsrv_close will return true because the first call to sqlsrv_close (in the error condition) sets the connection resource to null. |
Example
The following example closes a connection. The example assumes that SQL Server is installed on the local computer. All output is writing to the console when the example is run from the command line.
