for loops

[Anon]

Right, I have a php script that read a news entrylist file. It searches for those which match the category required, and prints the details to the page. It all works fine, perfectly, but then my news page gets too big, so I want to cut it down only to the last 10 items. Any ideas? I've already been told to replace my while loop with a for loop, but then I get an error (expect T-While).

<?
if (($value>0) and ($value<=$catlength)) {
$total_length = count($line);
do {
$this_entry = explode('|', $line[$i]);
if (($this_entry[7] == $sec) and ($this_entry[5] == "O")) {
do the stuff!
}
$i++;
}
while ($i <= $total_length);
}
?>

You could also use MySQL to fix this.

I assume your data is in a TXT file? Just use file() to read it into an array, trim the array to the last 10 items and write the array back to the TXT file with fwrite().

or...

use MySQL (recommended)

// if you want to count it out
// $count = 0;

for ($i = $start_at; $i <= $end_at; $i++) {

// $count++;

/ your code here /

}

This sounds like what I want to do, my script is already only reading certain items from the file (in fact it's a cgi file). How do I create an array that trims the file to only the items I want, and then read only the last 10 items of that array?

Many thanks,
