Hi, historically, the problem of listeners, triggers, etc, is that those things are what we call a 'design pattern'. When doing database programming, the DBMS calls the trigger. Inside Swing or GUI toolkit, the toolkit calls listeners by itself, since you register a listener with an object, to make the object able to signal the listener one of its properties has changed. In this field, if we tackle the problem of PHP, the problem is that whe need to register the PHP script with a file. And it can be made with stream_select wich calls the select() C POSIX function internally. The C select function makes some calls to the OS internals. then the kernel awake the process when the given file or stream has changed. http://fr2.php.net/manual/en/function.stream-select.php Good Luck, Laurent. 2005/12/19, mamontesines <mamontesines@xxxxxxxxx>: > Hi, > > Iam wondering has anyone tried a program that can do an onUpdate > function? like for example I want to run a program that waits until a > file is updated then a status report is displayed or the file is > displayed on update/change without any use of loops. > > like triggers....if a database is updated or new data is inserted > there will be a trigger that launch a file or function. > > if anyone has done this may you share it to us? > > thanks, > coco > > -- «Un peu d'internationalisme éloigne de la patrie; beaucoup y ramène» Jean Jaurès@<http://www.le-valdo.com> ------------------------ Yahoo!
