Reading from file....

[Anon]

I am writing a fairly simple messege board script... but I have come across a problem 🙁

I am trying to read from posts.txt, which has the values of the variables like this on each line: $title|$news|$username

now i want to separate this when I read it so i can print the variables back out onto the page.

I am also trying to limit it to 5 posts.

But, when i execute it all I get is the first post twice!?

here is my code:

<?

$display = "5";

$file = fopen ("posts.txt","r");

while (!feof ($file)) {
$lines[] = fgets ($file, 4098);

for ($i=0; $i < $display; $i++) {
list($title,$news,$username)=explode("|", $lines[$i]);
print "title: $title<br>news: $news<br>username: $username<br><br>";
}

}
?>

I would greatfully appreciate any help

thanks

Looks like you got the order a bit messed up.

You are putting the lines into the array while you are printing them, which makes no sense.

You should first read all the lines into an array, and then print them, or forget the array, and just print the lines immediately:

<?&nbsp;
$display&nbsp;=&nbsp;"5";&nbsp;
$file&nbsp;=&nbsp;fopen&nbsp;("posts.txt","r");&nbsp;
while&nbsp;(!feof&nbsp;($file))
{&nbsp;
&nbsp;&nbsp;$lines[]&nbsp;=&nbsp;fgets&nbsp;($file,&nbsp;4098);&nbsp;
};

if&nbsp;(count($lines)<$display)
{
&nbsp;&nbsp;$display&nbsp;=&nbsp;count($lines);
};

for&nbsp;($i=0;&nbsp;$i&nbsp;<&nbsp;$display;&nbsp;$i++)
{&nbsp;
&nbsp;&nbsp;list($title,$news,$username)=explode("|",&nbsp;$lines[$i]);&nbsp;
&nbsp;&nbsp;print&nbsp;"title:&nbsp;$title<br>news:&nbsp;$news<br>username:&nbsp;$username<br><br>";&nbsp;
}&nbsp;;

?>&nbsp;

or

<?
$display&nbsp;=&nbsp;"5";&nbsp;
$file&nbsp;=&nbsp;fopen&nbsp;("posts.txt","r");&nbsp;
$i=0;
while&nbsp;((!feof&nbsp;($file))&nbsp;&&&nbsp;($i++<5))
{&nbsp;
&nbsp;&nbsp;$line&nbsp;=&nbsp;fgets&nbsp;($file,&nbsp;4098);
&nbsp;&nbsp;list($title,$news,$username)=explode("|",&nbsp;$line);&nbsp;
&nbsp;&nbsp;print&nbsp;"title:&nbsp;$title<br>news:&nbsp;$news<br>username:&nbsp;$username<br><br>";&nbsp;
};
?>
