Ok - that last php test function was a combination of different attempts
- with several obvious errors. Something that actually almost works
follows - it almost works in that it does exactly what I want it to by
spewing the newly added events - but I'm only receiving the "ALLRAW"
event. The per node event that I THOUGHT I was creating in the firebird
trigger of "RAW:1234" appears not to be generated. Where am I wrong?

<?php
error_reporting(E_ALL);
header('Content-Type: text/event-stream');
header('Cache-Control: no-cache');
session_start();
$iplink_node = 1116;
$dbh = ibase_connect( 'test.fdb', 'SYSDBA', 'masterkey', 'ASCII' );
$evs = "RAW:$iplink_node";

while ( $handler = ibase_wait_event( $dbh, "ALLRAW", $evs ) ) {
// just keep looping...just keep looping...
echo "$handler\n";
$handler = "RAW:1116";
raw_line_handler( $handler, $dbh );
flush();
}

function raw_line_handler( $event_name, $dbh ) {
$iplink_node = substr( $event_name, 4, 4 );

echo "iplink is $iplink_node\n";

$qs = "select first 1 RAWLINE from RAW_IPLINK where IPLINK=? order
by RECEIVED desc";

$th = ibase_trans( $dbh, IBASE_READ );
$qh = ibase_query( $th, $qs, $iplink_node );

if ( $qh ) {
while ( $row = ibase_fetch_row( $qh ) ) {
echo $row[0] . "\n";
}
ibase_free_result( $qh );
}
ibase_commit( $th );

return true;
}

?>
