Curious PHP cli output in context of bash completion ?

Hello, I'm pretty "sure" (in realty I do not understand a lot about the problem... :( ) this is a distribution or a version problem but maybe some PHP/bash expert here could have some idea and tell me what I could try to solve the problem described here : http://ubuntuforums.org/showthread.php?p=8734334 Shortly : PHP cli seems to output something like newlines that bash can not intercept. My initial goal is to complete a PHP script, using the PHP script itselfs as function for bash completion. Mechanism that works perfectly on some other platforms (with different PHP AND bash version ...) than Ubuntu 8.04 and 9.10 (PHP 5.2.4 and PHP 5.2.10 respectively). The interest : only one thing to code : the php script. Moreover : the PHP scripts knows "things" (DB connection, .. etc) that the bash script would have some difficulty to get. Thank you a lot for any help. -- Alex
