Output the context of a text file

How do I output the context of a test file?

I am running apache/php on windows.

Lets say I have a text file in c:\textfile.txt

How can I write a php page which will just echo the contents of that file?

thanks

Use [MAN]file[/MAN] or [man]file_get_contents[/man] with [man]fopen[/man]

If you simply want to output it, readfile() is the most efficient although odds are you won't notice the difference.

thanks for your tips....

here is what i came up with

<?php

$file = fopen("testlogfile.txt", "r");
$content = fread($file, filesize("testlogfile.txt"));
fclose($file);
//print_r ("$content");

echo ("$content");

The problem is the browser doesnt display the textfile with carriage returns. Lets say the text file looks like this

line1
line2
line3

the browser returns this instead

line1line2line3

What am I doing wrong?
Also, how can I modify the code to only display the last 50 lines of the textfile?

Thanks again.

Actually the carriage returns do show up, check out your HTML source. The "problem" here is that a carriage return isn't HTML but rather the HTML equivalent would be <br>. So, you may want to do this:

echo nl2br($content);

thanks...any ideas on how I just return the last 50 lines of the text file?

$content=nl2br($content)
$lines=explode("<br>",$content);
$start=(count($lines)>=50)?$count($lines) - 50 : 0;
for ($i=$start;$i<count($lines);$i++){
echo $lines[$i] . "<br>";

}
