print out part of array

[Anon]

Hi.

I have a problem withs arrays - i want to take an array and print out, let say 20 of 40 rows, and the possibilty to reverse them. Looked around ín the manual but i am stuck.

The array is from lines in a file by the way.

I have this code example - it prints out the first four rows of the array - but if i want it to print out the four last one? I tried to use rsort but i could not get it to work. any ideas?

$fp=fopen($filnamn,'r');
while (!feof($fp))
{
$lines[]=fgets($fp,4000);

}
fclose($fp);

for ($i=0;$i< 3;$i++)

{
print $lines[$i];
}

One way:

$last = count($lines)-1;
for ($i=0; $i<4; $i++) {
print $lines[$last-$i];
}
