Counting Array Data Question.

[Anon]

Hello

i have a script which opens a flatfile textfile, in this format

something|something
something|something
something|something
something|something

only 2 fields (but about 10 lines)

and i have a script which prints
only 2 lines of the ten (which is what i want).. so it goes through it and finds the 2 lines depending on what query is given etc..

so heres the couple of lines of code that does this.

$dbFile = "./database.txt";
$data = file($dbFile);
$total = count($data);
for ($i = 0; $i <= $total; $i++) {
$wantedLine = $i;
$lineData = $data[$wantedLine];
$lineData = explode("|", $lineData);
if($show == "2 only"){echo "
<table border=0 cellspacing=0 cellpadding=2 width=98% align=center valign=middle bgcolor=#dedede>
<tr>
<td width='70%' ALIGN='LEFT'>FILE NAME: $lineData[0]</TD>
<td width='18%' ALIGN='RIGHT'>FILE SIZE: $lineData[1]</TD>
</tr>
</table>\n"; }
}
echo "total size is: $lineData[1]";

OK 🙂

so now if you look closely i also have it printing the data from teh second field aswell ($lineData[1]) is the second field incase your not following.

everything in teh second field is numbers only.. so im trying to calculate what $lineData[1]+$lineData[1]=
and getting the $lineData[1] value from the 2 differentlines in teh database..

i know iu can easly get the entire size of all $lineData[1] fields but i dont want to do that i only need 2..

if anyone can help or suggest a way to do this Please post 🙂

You want to add the total of $lineData[1] for the two loops right?

An easy way is just add a variable to let the values add together during the loop. See below.

for ($i = 0; $i <= $total; $i++) {
$wantedLine = $i;
$lineData = $data[$wantedLine];
$lineData = explode("|", $lineData);
if($show == "2 only")

$line_totals = $linetotals + $lineData[1];

{echo "
<table border=0 cellspacing=0 cellpadding=2 width=98% align=center valign=middle bgcolor=#dedede>
<tr>
<td width='70%' ALIGN='LEFT'>FILE NAME: $lineData[0]</TD>
<td width='18%' ALIGN='RIGHT'>FILE SIZE: $lineData[1]</TD>
</tr>
</table>\n"; }
}
echo "total size is: $line_totals";

Good Luck

that just prints the value of the last line counted..

thanks for trying.

Something like that should work.

I miswrote the line.
$line_totals = $linetotals + $lineData[1];

should be:

$line_totals = $line_totals + $lineData[1];

Good luck
