Get lines from a file...

[Anon]

Hi guys!
I got a problem here...I guess it's an easy question but I couldn't find any asnwer on internet...
Here it goes:
How can I get only the first 5 lines of a file and attribute its value to a variable so then I can echo/print the info??
Thanx in advance

$file = fopen($filename,'r');

$linenumber=0;
while (linenumber < 5)
{
$thevalue .= fgets($file,10000);
$linenumber++;
}
FClose($Floginfile);

echo "The value is $thevalue";

Thanx!

But if I use the file() function...I got this code:

<?
$limite = 3;
$links = "links.txt";

if ($numero != 0) {
$linhas = file($links);
$linhas = preg_replace("/#/", "\n", $linhas);
for($i=0; $i < $limite; $i++) {
print $linhas[$i];
}
}

?>

But I want to store what I get in a variable instead of print it, so then I can use the join() function and put only those 3 lines in a file....what should I do then?
Thanx in advance

Why would you use the file function? The code I suppied puts all the results into 1 variable, which is what you asked for; I thought anyway 😉

Sorry...I was just wondering how I could do that with the file() function...Thank you :-)

I went back and looked, and if you want to put the results in a variable, if thats what you mean, alls you do is change that last line..

<?
$limite = 3;
$links = "links.txt";

if ($numero != 0) {
$linhas = file($links);
$linhas = preg_replace("/#/", "\n", $linhas);
for($i=0; $i < $limite; $i++) {
$joinedresult .= $linhas[$i];
}
}

?>

And lets say that I'd like to keep the lines, is it gonna work:

<?
$limite = 3;
$links = "links.txt";

if ($numero != 0) {
$linhas = file($links);
$linhas = preg_replace("/#/", "\n", $linhas);
for($i=0; $i < $limite; $i++) {
$joinedresult .= "$linhas[$i]\n";
}
}

?>

It should.. only one way to find out though 😉
