get lines from file

[[deleted]]

Hi All

<?php

$fcontents = file ('http://www.some-url.net');
while (list ($line_num, $line) = each ($fcontents)) {

echo $Line
}

?>

This script gives me opportunity to get another page in array and print it out, but I don’t need to get all lines from page, I need get only lines for example from 100 – 300; I have no idea how to implement this operation please help me

<?php

$fcontents = file ('http://www.some-url.net');
while (list ($line_num, $line) = each ($fcontents)) {
<B>
if ($line_num >= 100 && $line_num <= 300) {
echo $Line
}
</b>
}

?>

That will limit what prints out. You can't limit what is returned by the server.

A more efficient way to do this would be to break if line > 300 so file parsing stops when it's no longer needed.

$start = 100;
$end = 300;
foreach (file('someurl.net') as $line) {
if (++$line > $end) break;
if ($line >= $start) echo $line;
}

Couldn't this also be accomplished with
$start=100;
$end=300;

$file = file('http://someurl.net');
$numlines = count($file);
if($numlines < $end) {
$numlines = $end;
}
for($i=$start;$i<=$numlines;$i++) {
echo $file[$i];
}

It's a little more code, but you ONLY parse the lines that you want.

yea, I'm sure there's a thousand other ways too. I did it my way becuase it uses less variables so you don't need to worry about unsetting them later (like the $file var in your example)....it's really up to the end developer but I personally prefer really tight code.

eep...huge bug in that earlier version...had $line doing two things.

$start = 100;
$end = 300;
foreach (file('someurl.net') as $line) {
if (++$linenumber > $end) break;
if ($linenumber >= $start) echo $line;
}

<?PHP

function right() {

echo "
<TD CLASS=\"Poll\" WIDTH=\"118\" BGCOLOR=\"#ffffff\" VALIGN=\"TOP\">
";

   $start=6; 
   $end=30; 

   $file = file('http://itavisen.no/script/jsfeed.html'); 
   $numlines = count($file); 
   if($numlines < $end) { 
   $numlines = $end; 
   } 
   for($i=$start;$i<=$numlines;$i++) { 
   echo $file[$i]; 
   }

echo "
</TD>
<TD BGCOLOR=\"#3E7195\" WIDTH=\"2\">
<FONT></FONT>
</TD>
</TR>
</TABLE>
";
}
?>

anyone know what's wrong with that code?
