My wife and I take a lot of pictures with our digital camera. I have a
Linux web server with a static IP address and we have a digital photo
page. It consists of a photo index displaying 100x100 photos organized
into tables by date. If someone clicks on one of the small pictures it
loads the full size picture. Until recently I had been using a program
I wrote in Visual Basic 6 to generate the photoindex.html page and then
uploading it to my server box. My computer is not doing well in Windows
anymore and I'd prefer to use Linux for as much as possible, so I've
been trying to convert my VB program into PHP. I thought I had the
script right, but I keep having problems. I fixed what errors I could,
but then attempting to load the page kept overloading mozilla. I wrote
to one of my Linux lists about this problem and someone suggested that I
use wget from a terminal to wget the file from the web server and look
at it. I did this and what I saw disturbed me.
My VB program (and now my script) was written to read a master list
called "list.txt". This list.txt would contain the filenames of other
lists. The "sub-lists" contained filenames of images that the program
would use to construct the html page that it would return to the
requesting browser. My VB program worked fine. However my PHP program
not so good.
Here is the code for my PHP script:
<?
function newTable($filename)
{
$count = 0;
$strDir = substr($fileName, 24, 6);
$strMonth = substr($strDir, 0, 2);
$strDay = substr($strDir, 3, 2);
$len = strlen($strDir);
$strYear = substr($strDir, ($len - 2), 2);
$subfile = fopen("$filename", 'r');
while (!feof($subfile))
{
$subfileline = fgets($subfile, 1024);
$count++;
}
fclose($subfile);
$subfile = fopen("$filename", 'r');
print " <center>\n";
print " <h3>Added $strMonth/$strDay/$strYear</h3>\n";
print " <br><br>\n";
print " <table cellspaceing='0' cellpadding='4'>\n";
While (!feof($subfile))
{
While ($count > 5)
{
print " <tr>\n";
for ($x = 0; $x < 4; $x++)
{
$subline = fgets($subfile, 1024);
$intAltLen = strlen($subline) - 4;
$strAlt = substr($subline, 0, $intAltLen);
$strLink = "mini-$subline";
print " <td align='center' valign='top'>\n";
print " <a href='$strDir/$subline>\n";
print " <img src='$strDir/mini/$strLink' width=100
height=100 alt='$strAlt>\n";
print " </a>\n";
print " </td>\n";
}
print " </tr>\n";
print "<!- End group-->\n";
print "\n";
$count -= 5;
}
print "<tr>\n";
for ($x = 0; $x < $count - 1; $x++)
{
$subline = fgets($subfile, 1024);
$intAltLen = strlen($subline) - 4;
$strAlt = substr($subline, 0, $intAltLen);
$strLink = "mini-$subline";
print " <td align='center'>\n";
print " <a href='$strDir/$subline>\n";
print " <img src='$strDir/mini/$strLink' width=100
height=100 alt='$strAlt>\n";
print " </a>\n";
print " </td>\n";
}
print "</tr>\n";
}
print " </table></center>\n";
print "<br><br>\n";
fclose($subfile);
}
$title = "My Pictures"; //<title> of page
$bgcolor = "#000000"; //<bgcolor> of page
$text = "#FFFFFF"; //<text> of page
print "<html>\n";
print " <head>\n";
print " <title>$title</tite>\n";
print " </head>\n";
print "\n";
print "<body bgcolor='$bgcolor' text='$text'>\n";
print "\n";
print "<center><h1>$title</h1></center>\n";
$mainfile = fopen("list.txt", 'r');
while (!feof($mainfile))
{
$mainfileline = fgets($mainfile, 1024);
newTable($mainfileline);
}
fclose($mainfile);
print " </body>\n";
print "</html>\n";
?>
This script sits in /home/michael/webspace/html/camera along with all
the list files. Here is the contents of list.txt:

There's not a permissions problem - everything in the camera directory
is chmod'd 755. The apache web server
sees /home/michael/webspace/html/camera/picindex.php as
http://192.168.1.2/members/michael/camera/picindex.php . When I wget
the file the the file size is 88MB (very disturbing.) The first few
lines of the file are:
[EMAIL PROTECTED] michael $ cat picindex.php | more

The entire file is full of lines like the ones above. The list files
exist and it's not a permissions problem:

In my script I think I have double quotes in all the right places, yet
the output file doesn't show them in the script. Where am I messing up
and how do I make this right? Our digital camera died back in February
and we can finally afford to replace it with a new one. It should be in
any day now and I'd like to have this script ready by then because we
just got a new kitten (lots of photo opportunities!) Please help!
