n lines from file

[Anon]

Hi,

i want to get n lines from $url after a certain string is found. I've tried this but
without positive results.

<?php
$url="http://some.url.com"; // some url
$fd = fopen ($url, "r");
$cur_line=1;
$query_str="Query"; $num_lines=6; $size=filesize($fd);
$size=100; // due to time to compute fileseize
echo '<li>Filesize='.$size; //debug

while (!feof ($fd) && $cur_line<=$num_lines)
{
$buffer = fgets($fd, $size);
$pos = strpos ($buffer, $query_str);
if ($pos)
{
echo '<li>POS='.$pos;
$res=fgets($fd, $pos+$cur_line+100);
echo '<li>'.$cur_line.' - '.htmlentities($res).'+';
$cur_line++;
}
}
fclose($fd);

?>

Marty,

One thing you might want to try is the file("filename") function. It reads in the file line by line into an array. Then you probably want to walk through the array looking for that term. Once you find it grab the next 2 lines. Something like the following might help.

$fp = file("test.data");
for($i = 0; $i < count($fp); $i++) {
if(search for string and match) {
$desired_string = $fp[++$i] . $fp[$i+2];
}
}

I am sorry this isn't more precise, but I am on my lunch break. Hope it helps you out.
