return a single line from a text doc

[dandono]

hi, using fread how do you get it to return a single line from a text doc. like with this kind of code

<?php
$line = $_GET['line'];
$uid = $_GET['uid'];
$filename = "D:/inetpub/xproot/users/" . $uid . "fav.txt";
$handle = fopen($filename, "r");
$contents = //make $contents to be what is on line defined by $line;
fclose($handle);
echo $contents;
?>

i have googled this and all it had was some other things that had nothing to do with my question. this is something to do with a program i am making which uses msinet to get what is returned into a string or text box.
thanks, dandono

Have a look at the file() function - it should help you

Because the function returns the array, just pass the $line as the index to get the required line

i think that this is not the best way to do this but it is the only way i can think. now somebody is going to come up with a code a houndred times better than mine in like five minuets.
this is my code. i will set it to open a local text file in a bit.

<?php
// Get a file into an array.  In this example we'll go through HTTP to get 
// the HTML source of a URL.
$lines = file('http://www.php.net/');
$no = $_GET['line'];

// Loop through our array, show HTML source as HTML source; and line numbers too.
foreach ($lines as $line_num => $line) {
if ($line_num == $no)
echo "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br />\n";
}

// Another example, let's get a web page into a string.  See also file_get_contents().
$html = implode('', file('http://www.example.com/'));
?>

thanks for the help

how do you get that code to view a text doc on the server mechine like the path D:/blah.txt? is it just with fread?

To get just the first line of a file use the fgets() function.

sorry i fixed it a different way like this:

<?php
$uid = $_GET['uid'];
$file = "D:/inetpub/xproot/xorite/browser/" . $uid . "fav.txt";
// Get a file into an array.  In this example we'll go through HTTP to get 
// the HTML source of a URL.
$lines = file($file);
$no = $_GET['line'];

// Loop through our array, show HTML source as HTML source; and line numbers too.
foreach ($lines as $line_num => $line) {
if ($line_num == $no)
echo  htmlspecialchars($line) . "<br />\n";
}

// Another example, let's get a web page into a string.  See also file_get_contents().
$html = implode('', file($file));
?>
