Default Still problem with files
Hi,

Sorry for the extra emails, but I thought I had this licked, but now
other problem pop up. As I said, I have a file with many lines like
<Option Value="3">Alfredsson in it. I have been able to read the file
into an array and display it, but I am trying to do a comparison IF
statement and no matter what I try I can't figure out what to compare.
To explain better here is my code so far.

$filename = "players.inc";

$fd = fopen ($filename, "r");
while (!feof ($fd)) {
$buffer = fgets($fd);
$list[] = $buffer;
}
fclose ($fd);

for($i = 0; $i < 131; $i++) {
if($list[$i] != ????????? {
echo "<BR>".htmlspecialchars($list[$i]); }
}

So using the example above what would I use where the question marks are
if I wanted to display everything but this line - <Option
Value="3">Alfredsson. I have tried a variety of ways to do this:

i.e

$p = "<Option Value=\"131\">Alfredsson";

for($i = 0; $i < 131; $i++) {
if(htmlspecialchars($list[$i]) != $p) {
echo "<BR>".htmlspecialchars($list[$i]);
}
}

This is just a sample script that I want to get running before I
actuaaly put it into use, so any help is appreciated.

Default RE: [PHP] Still problem with files
For whatever reason your suggestions still caused me problems, but I did
come up with a solution that works.

if (preg_match ("/Alfredsson/", $buffer))

Another question though regarding \n. What I'm doing here is reading the
file, omitting one entry, adding another, and saving it back to the
file. When I add the entry and save it back to the file it appears
beside the last entry instead of below it. How do I get it so it is
below it. I have tried using a \n but no go. I am probably missing
something, but not sure what. This is the first time I've played with
files in PHP.

i.e.

<Option Value="155">Roy, P
<Option Value="77">Theodore
<Option Value="26">Thibault<Option Value="68">Worrel

And watch out for case sensitive issues
'Option' != 'option'

Using file() instead of the above would be much easier.

If you're going to be using file() then:

if($list[$i] != "<Option> Value=\"3\">Alfredsson\n";

Note the \n, substitute for whatever CR/LF characters are present in your
file because file() leaves them intact.

Have you looked at the file() function? it does all this work for you.
http://php.net/file

Be careful with loops like this you might want to use the foreach
statement in this case

http://us3.php.net/foreach

first of you dont want to compare the value with the htmlspecialchar()
function, only use that to translate html chars like < to &lt; so the
browser is will display the html code instead of rendering it.

second, the fgets() you used above still has the carriage return on it
so you will need to chomp that off or add it to your compare string.

http://php.net/trim

I hope that helps you getting it running.

I would recomend using
if(trim($list[$i]) != "<Option> Value=\"3\">Alfredsson")

it will handle the any problems with DOS or UNIX text files.

Default RE: [PHP] Still problem with files
Yep, but am I doing it right I don't know. This is the line that will be
written to the database (there will be 130 of them).

$p = "<Option Value=\"131\">Player Name";

So where do I put the \r\n. I have tried just \n at the end, but same
thing.

$p = "<Option Value=\"131\">Player Name\n";

TIA

It beats me why you're not storing the info in a DB rather than a file.

Anyway here's some psuedo-code:



$file = file('file);
foreach ($file as $line => $data) {
$file[$line] = trim($data);
if (!strcmp($what_you_are_looking_for, $file[$line])) {
// found, do your replacement stuff
}
}

implode('choose a suitable EOL character(s)', $file);
write_out_file();

If it's not obvious from examining the code then you have to get down to some
serious debugging. Most importantly you need to:

- incorporate error checking into your code, examine the values returned from
all functions

- var_dump() all your major variables and verify that they are what you
expect them to be
