for-loop problem

[techmeister]

Hi all:

Does anyone know of a method of echoing results from within a for-loop to the page LATER in a script rather than at 'point-of-execution'? - (Instead of straight to the page within the loop.)

I have a for-loop that echoes No: pages from a search result to the page, as hyperlinks:

for ($i=1;$i <= $pages; $i++) {
$newoffset = $limit * ($i - 1);
echo = "<a href=\"$PHP_SELF?offset=$newoffset\">$i</a>";
}

The value of the echoed portion changes, as it reflects thwe number of pages in a search to display. If there are 2 pages to be displayed then; "1, 2" is echoed as hyperlinks to those pages. But if I pass the result to a var and then echo the var to the page I simply get " 2 " which reflects the number of the pages yes, but not in the " 1, 2 " format which is what I need!

Cheers for any pointers!
Russ.

Hopefully I'm not missing the point here, but why don't you just build up your output to a variable and then echo/printf the variable when you are ready to display it.

E.g.

for ($i=1;$i <= $pages; $i++) {
$newoffset = $limit * ($i - 1);
$op = $op . "<a href=\"$PHP_SELF?offset=$newoffset\">$i</a>";
}

.
.
.

printf("%s", $op);

.
.
.

Hope this helps,

You are a master!!

Just like that and it worked!! I honestly wasn't aware of that 'technique'!!

Many thanks to you! (I posted this same piece yesterday and no-one answered!)

Nice one : )
