Thanks NC, that give me something to think about. As a C/C++/OP
programmer for 15 yrs now I struggle with language constructions like
($data as $line) so I'll have to think on this method a bit.

I finally found that "\r\n" was the correct end of line sequence. The
trouble however, is that even if I rtrim() the line, I still need to use
this as the indicator. Does that mean that rtrim() isn't properly
removing them or am I missing something? I don't know but I'm up and
running so for now that's water under the bridge.

Just to summarize what I ended up with

$page = array();
$file = 'fleet.tdb';
$data = file($file) or die('Could not read file!');
$blk = array();

function getNextDataBlockEndIndex() {
global $data;
$stopmark = "\r\n";

$i = -1;
do {
if (++$i < count($data)) $line = $data[$i];
//rtrim($line); // makes no difference
} while (($i < count($data)) AND (!(strcmp($line, $stopmark)
== 0)));
return $i;
}

function getNextDataBlock() {
global $blk;
global $data;

$idx = getNextDataBlockEndIndex();
$blk = array_slice($data, 0, $idx);
reset($data);
$data = array_slice($data, $idx+1);
}

function getNextPlaneBlock() {
global $blk;
getNextDataBlock();
if (! empty($blk)) {
echo "<div class=\"ad_note\">";
echo "<div class=\"fleet_tn\"><a target=\"pic_view\"
href=\"images/fleet/$blk[1]\">
<img src=\"images/fleet/$blk[2]\" border=\"0\"
alt=\"thumbnail\" /></a></div>";
echo "<p class=\"fleet_text\" />";
echo "$blk[3], $blk[0]<br />$blk[4]<br />$blk[5]<br />$blk[6]
<br />$blk[7]<br />";
echo "<br />&nbsp;";
echo "</div>";
return 1;
} else return 0;
}


Then later within the body of the document all I need is,

<!-- Fleet box -->
<center>
<div class="fleet_box">

<!-- Plane -->
<?php do ; while (getNextPlaneBlock() == 1);?>

</div>
</center>


And I have a completely dynamic listing of the entire fleet managed by a
simple text file with no further intervention required.

Now, I do have a slightly expanded data file, the original was simply an
example... but more importantly easily expanded in the future and if new
data needs to be added I simply adjust the use of the $blk[x] elements
in the output function getNextPlaneBlock(), one time only.

If anyone has any ideas or comments on something I've done wrong,
inefficiently or how to simply make the method better, I'm ALL ears.
Thanks for the input...
