PHP foreach() return only last 50 items

Question

I am currently using the following PHP code to return and format output from an .htm file:

\";
$lines = file(\"http://www.example.c         


        

Answer 1

You're looking for the array_slice function:

array_slice() returns the sequence of elements from the array array as specified by the offset...

$lines = file(...);
$lines = array_slice($lines, -50);

Answer 2

Use array_slice() to slice off the last 50 elements of $lines prior to running the foreach() { } loop.

$lines = array_slice($lines, -50);

Answer 3

Another alternative is to do the calculation your own and skip all but the X last ones:

$last  = 50;
$count = count($lines);    
foreach ($lines as $line) 
{
    if ($count-- > $last) continue;
    ...
