Re: [PHP] How do I read the first n lines from a file?
If the lines terminate in "\n", I'd use fgets($fp,1000) in a loop, and loop
as many times as needed.
$fp=fopen("filename","r") or die ("couldn't open filename");
for ($count=1;$count<=10,$count++)
{
$line=fgets($fp,1000); // the 1000 represents the number of bytes to
go to unless it finds "\n" sooner.
print "$line";
}
I'm prety sure the above will work.

Re: [PHP] How do I read the first n lines from a file?
You might be better off using the file() function which reads a file into an
array, then you can use the indexes to get whatever lines you want

RE: [PHP] How do I read the first n lines from a file?
Yes. Then you have to do it a bit differently:
$file = file("list.txt"); // $file is now an array of lines in "list.txt"
for ($i = count($file); $i > count($file) - 10; $i--) {
print "$file[$i]";
};
That should do. Didn't try it thou. That prints the lines in order last,
last-1, last-2

You can do this:
$i = 0;
$fp = fopen("list.txt", "r");
while (!feof($fp) && $i < 10) {
$i++;
$Text = fgets($fp, 4096); // Reads first 4096 characters from a row.
print "$Text\n";
