Displaying a specific line

[Anon]

Hi,
I have a script which displays data from a text file, creating a new html
line for each line in the text file. So far this works.

$array=file("newsarchive.txt");
foreach ($array as $line)
if (ereg("^{([\t])\t+([\t])$",} trim($line), $reOut)) {
echo "$reOut[1]<br>";
}

========
newsarchive.txt

12 News date 12....
13 News date 13....
14 News date 14....

...

However, I would like a different script that would display only a specific
line from that text file, using one of the variables at the beginning of
each line (the number at the beginning in my example). I would call this
specified variable in the URL.

Can anyone help?
Thanks

Not sure where the tabs are in that example, but if $var is the variable you want to search on, such stick $var into your regexp in the appropriate place (at the start of the line? right after the first ^). Variable substitution works as per usual.

Excellent, that was not quite it but i figured it out. I needed to place the variable inside the [], like so:

ereg("^([$var\t]*)

Thank you!
