Help with flat files, please!

[johnnn]

Im a pretty decent PHP "coder";
I'm currently working on my own flat file blog (so its custom.....)

For blog comments,
In stead of creating a new txt file for each post, I want just one.

My problem is, reading the comments, heres what I've come up with so far:

<?php
define(COMMENTS, "comments.txt");
foreach($comments as $dbRows) {
list($name, $url, $datePosted, $comment, $ip, $title) = explode("||", $dbRows);
if($title == $t) {
echo $comment;
}
}
?>

The problem is when I run that query it only show the data i request from one
..... heres an example
John||@||time()||Hello!||00.000.000.00||First Post
Smith||[e-mail]||time()||Hi!||First Post
Riley||@||time()||Hola!||Second

when that query run, it will only read one line where $title = First Post
I want it to read all lines like that
and if it the title, for example - Second, I want it only display the rows with the same title 'Second'

HELP WILL BE GREATLY APPRECIATED.
Hope this isnt to confusing =\

In your example data you do not have the same number of fields on each line.

my bad on the whole not equal values rows, ignoring that use these lines:
JUST AN EXAMPLE

1||e||s
2||s||n
3||p||s

in each row the first part, (number) will be $id, the second will be $inital, and the thired wil be $whatever.
how can i read only the lines where $whatever will be the same, like:
lines 1 and 3?!

store those comment in $whatever/$whatever_comment.txt
then you musn't create a compare

is it a bad idea?

A little off topic, but must you really use flat files? One of the uses of the lightweight SQLite database engine is as a "replacement for fopen()" (i.e., for flat file databases), so why not consider it? There would be no database server to install, and the PDO extension and its SQLite driver are installed by default in PHP (though they may need to be enabled).
