I think what Tedd was referring to was something else. The hole was quite large. I've seen this behavior myself, in PostgreSQL. From one transaction to the next, there were over 10,000 skipped numbers, and only me and my wife on the system. Some sort of bug, like a spinlock that wasn't interrupted the way it should have been. I remember the system taking forever to calm down before it gave the next transaction a number way forward of the last one. I waited in front of my browser for quite some time. But I couldn't explain why. Paul -- Paul M.

Re: [PHP] Problem with variables
Fernando A soporteallpurp...@gmail.com wrote: I am working with php and codeigniter, but I have not yet experienced. I need create a variable that is available throughout system. This variable contains the number of company and can change. as I can handle this? Hi, Fernando, welcome. I'm just a little unsure what you mean by number of company -- is this a count, as in 10 companies, or is it a phone number, or is it something else? Jim's reply is workable -- storing session values is quite useful, but sessions are tied to a specific browser client/ip, and I'm not sure that's what you want/need here. If you are looking for setting a global variable that will be available everywhere in your application, you can use $GLOBALS, or set it from the very top level context of the application. Given you're using CodeIgniter, which sadly I am not versed in, you may need to set it with $GLOBALS: $GLOBALS['my_var'] = 10; // whatever you need to do here When you say it changes, how and when exactly does it change? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Cheers, tedd _ tedd.sperl...@gmail.com http://sperling.com I have no answers as to why the huge skip forward, the huge skip backwards though makes me think someone else is doing something in the database, and all the alarums and red flags are waving.
