[PHP] grabbing variable from bottom to top
Anyone know of a way to use a variable that isn't defined until further down the script at the top. I have a counter and once everything runs through the script, the count is complete, I need to display this at the top above the displayed results. I thought about and tried a function but I still run into the same problem. thanks -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] grabbing variable from bottom to top
You can't get the intended value from a variable that hasn't been
defined yet, obviously because you haven't given the variable a value.
If you are trying to make something like a counter you may consider one
of the following:
1. Insert the value into a database like MySQL or PostgreSQL,
2. Write the variable to a text file
3. Use PHP Sessions to store the variable between requests.
Of these choices #1 is generally the best choice, #2 will not deal with
concurrent requests well and may corrupt the information, #3 will only
work for a single visitor.
If the values are in an array you might use count($array) that will tell
you the number of elements in the array, if the values are a delimited
string you can use count(explode('seperator', 'data')) or something like
that. The other thing you can do is run through the loop and instead of
printing output put it into a variable, then at the end of the loop
print the number, then print the variable containing the output, then
print the end text.

Re: [PHP] grabbing variable from bottom to top
Ok, this is completely off the top of my head, and there is more than
likely a better way, but if you HAVE to do this, then I guess here's an
option:
1. turn on ob (output buffering at the top of the script
2. where you want the counter to be, echo something unique like
[EMAIL PROTECTED]@
3. once the script has ended flush the contents of OB into a variable
like $obContents
4. do a str_replace('[EMAIL PROTECTED]@',$yourCounterValue, $obContents)
5. echo the $obContents to the screen
I think a smarter way would be to re-organise your code somehow so that
it does what you want, but maybe that can't be done (no way to know
without seeing the code).
Good luck,
