pg_connection_status
Get connection status
(PHP 4 >= 4.2.0, PHP 5)
Example 1909. pg_connection_status() example<?php Code Examples / Notes » pg_connection_statuszytox
If the connection variable is NULL this function returns 0 in PHP 5.0.2. Havent figured out any more erratic values for the connection variable but be careful.

I think zytox is incorrect, at least in PHP 5.0.4. It returns null, but you have to be careful with your comparison operators. As an example: <?php unset($null); if (pg_connection_status($null)===PGSQL_CONNECTION_OK) echo 'this is not called'; if (pg_connection_status($null)==PGSQL_CONNECTION_OK) echo 'this is called because NULL==0 is true'; ?> mathieu de zutter
Being careful with the comparison operators is not enough: <?php if (pg_connection_status($link)===PGSQL_CONNECTION_BAD) reconnect($link); ?> The reconnect won't be trigged when $link is null. The manual is just wrong, there are three return values: PGSQL_CONNECTION_OK, PGSQL_CONNECTION_BAD, null |
