[RESOLVED] Read last five lines of a file then echo them

[rallan]

How would I go about doing this?

[djjjozsi]

it is a simple code to do that.

<?php
       //file command you can open a file, and read its contents into an array.
	$lines = file('file.txt');

// Count this array
    $li=count($lines)-1;
$a=0;
while($a<5)
{
	print $lines[$li-$a]."<br>\r";
	$a++;
            //  don't forget to increment your counter
}
?>

hello,
jjozsi.

Note that the above solution would load the entire file into memory, even though this isn't necessary. You could optimize memory usage like so:

<?php

$file = fopen('file.txt', 'r');

for($i = 0; $i < 5; $i++)
    echo fgets($file, 8152);

fclose($file);

?>

Not resolved: How do you make it echo the newest line at the bottom and the oldest line at the top?
