!!! Question !!! about catching Exceptions

[sarral]

Trying to trap when I can't connect to the cluster.

Thank you for your help.

I have looked everywhere (except where an example is, haha) to find an example
I'm kinda new to PHP, but experienced programmer.

I'm going to try this as a script, without using a Class

class CassCore
{
...

function __construct() {
try {
$this->rCONN = new ConnectionPool(self::KS, $this->servers);
}
catch( NoServerAvailable $e ) {
echo "No Connection to Cluster\n";
die("FOUND EXCEPTION\n");
}
catch( phpcassa\Connection\NoServerAvailable $e ) {
echo "No Connection to Cluster\n";
die("FOUND EXCEPTION\n");
}
// Connect to CFs
......
return;
}

and what i receive:

Error connecting to 191.168.1.50: TException: TSocket: Could not connect to 191.168.1.50:9160 (Connection timed out [110])

nevermind.... figured it out.

try {
$this->rCF_ip = new ColumnFamily($this->rCONN, self::CF_ip);
$this->rCF_det = new ColumnFamily($this->rCONN, self::CF_det);
}

catch( phpcassa\Connection\NoServerAvailable $e ) {
echo "4: No Connection to Cluster\n";
die("FOUND EXCEPTION\n");
}

FYI for other users.

Are you using the autoloader (autoload.php)? If so, try adding 'use
phpcassa\Connection\NoServerAvailable;' to the top of your script, and your
first catch block should work.

Yes.

require_once('../phpcass/lib/autoload.php');

It's probably better to catch early (ConnectionPool) rather than what I figured out to do: Catch on ColumnFamily init.

my second comment did work. Going to do your suggestion.

Thanks.
