fbsql_close — Close FrontBase connection
Closes the connection to the FrontBase server that's associated with the specified link identifier.
Using fbsql_close() isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution.
A FrontBase link identifier returned by fbsql_connect() or fbsql_pconnect().
If optional and not specified, the function will try to find an open link to the FrontBase server and if no such link is found it will try to create one as if fbsql_connect() was called with no arguments
Returns TRUE on success or FALSE on failure.
Example#1 fbsql_close() example
<?php
$link = fbsql_connect("localhost", "_SYSTEM", "secret")
or die("Could not connect");
echo "Connected successfully";
fbsql_close($link);
