Limiting number of links on a page

[webmasts]

Hi,

I would like to allow visitors to add links on my page using the fopen() and fwrite() functio, storing the links on a text file and then displaying it on a webpage. I want to limit the number of links that can be allowed in a page. Let say I want 100 links on a page. If the links added goes over 100, then the old links goes to the next page. I want to keekp the NEW 100 links on the main page.

How would you do it?

Thanx

I think this might work:

use the readline() function

<?php
for ($i=$start; $i < $limit; $i++) {
$line = readline ("Link: " );
readline_add_history ($line);
}

print_r (readline_list_history());

?>

the $start on the first page wold be zero and $limit would be 101.

and when the first page is displayed...your link to the second page would make $start = $limit [previous one, i.e 101] and your $limit = $201

and so on.

The only thing I cannot figure out how to make the readline() function start reading from line 101 to 201 or end of file if numbre of links < 201.

maybe there is a countline function somewhere or you can implement your own...sometihng like setting a flag (anchor?) after 101 and 201 etc.

it could work.

hmm, I am not good with these files commands but I am still going to post.
I think astericks that this is quite opposite since I guess that new links are always added at the bottom of the file.

I would read all the lines into an array and order it backwards and then use for loop to print it out.

Just in idea though...

end of file...hmmm

well, you could use
http://www.php.net/manual/en/functio...t-contents.php

and then use the explode() function alongwith a delimiter to put your results in an array, get array size and do the same limit thing i posted above except that you'll be going from end_of_array to end_of_array - 100

it doesnt sound too efficient though.
