Shell Programming and Scripting

Hi, I have the code below which outputs all the lines of a CSV file but I'd like it to only output 15 lines then save the current line as a variable which could be used (as a link) to display the next 15 lines. I can't get my head around the logic! Please help

while ($data = fgetcsv($fp, 1000, "~")){
$num = count ($data);
$i++;
print '<td>';
print "<a href=\"" . $data[2] ."\"><img src=\"" . $data[2] . "\"></a><br>";
print "Submitted by:<br>";
print $data[1];
print '</td>';

if ($i == 5){
print '</tr>';
$i=0;
}
}
print '</table>';
fclose ($fp);

Many thanks,

I went with a database solution in the end but the method to display the output would've been the same - here's the final code:

print '<table class="tborder" border="0" width="95%" align="center">';
$t=0;
print '<tr>';
while ($data=mysql_fetch_array($result)) {
// include code to display results as you see fit

$t++;
print '<td align="center">';
print "<a href=\"" .$data['link']."\" title=\"Add An Image - Link No. ".$data['linknum']."\"><img src=\"phpThumb.php?src=" .$data['link']. "&w=100\"></a><br>";
print "submitted by<br>";
print $data['name']."<br>";
print $data['date_entered']."<br>";
print '</td>';

if ($t == 5) {
print '</tr>';
$t=0;
}
}
print '</table>';

print '<p align="center">';

// next we need to do the links to other results

if($offset >= $limit){
$newoffset=$offset-$limit;
print "<a href=\"$PHP_SELF?catagory=$catagory&offset=$newoffset\">PREV</a> ";
}

// calculate number of pages needing links
$pages=intval($numrows/$limit);

// $pages now contains int of pages needed unless there is a remainder from division
if ($numrows%$limit) {
// has remainder so add one page
$pages++;
}

for ($i=1;$i<=$pages;$i++) { // loop thru
$newoffset=$limit*($i-1);
if ($newoffset != 0){
print "<a href=\"$PHP_SELF?catagory=$catagory&offset=$newoffset\">$i</a> &nbsp; \n";
}
}

// check to see if last page
if($numrows-$offset > $limit){
$newoffset=$offset+$limit;
print "<a href=\"$PHP_SELF?catagory=$catagory&offset=$newoffset\">NEXT</a>\n";
}
print '</p>';
