The support for message-strings send by triggers is not implemented.
The common error send by triggers is the -746.

Nice function to call. Very helpfull if you want to use in combination with an own ErrorHandler. But informix error recognition seems just to work directly after calling a informix function.
/**
* checks weater error has occured or not
* @return false if no error, else error message
*/
function db_error_occured()
{
$err_code = ifx_error();
if (substr($err_code,0,1) != ' ') {
return ifx_errormsg();
}
else {
return false;
}
} //db_error_occured
