Requesting Help [PHP]

Hey guys, I've been having a tough time figuring this out. Right now, I have a .txt file with article entries inside it. I want a script to read each entry, and echo it to the browser, but I want it to stop echoing to the browser when it echoes 10 entries. Here's what I have so far:

php code



<html>
<body>

<?php

$data = file_get_contents('data.txt');
$entries = explode('|', $data);
$x = 0;

foreach($entries as $entry)
{
   $x++;
}

if($x > 11)
{
   echo "<br>";
   echo implode($entries);
}

?>

</body>
</html>

The script I made obviously doesn't work.

It continues to echo article entries to the browser even after 10 entries have been echoed. Can anyone help me out? It'd be appreciated.

Here ya go buddy. Its a little more than you asked for as it has built in error checking so you don't try to loop stuff if nothing exists. Its untested but looks pretty clean.

php code



<?php

$data = file_get_contents('data.txt');
$entries = explode('|', $data);

/*COUNT HOW MANY ENTRIES THERE ARE*/
$total = count($entries);

/*SET THE LIMIT AS 10 IF THE TOTAL ITEMS IS MORE THAN 10, OR JUST AS MANY AS YOU HAVE IF NOT*/
if($total > 10) {
    $limit = 10;
} else {
    $limit = $total;
}

/*ONLY PERFORM THE LOOP IF THERE ACTUALLY ARE ENTRIES*/
if($limit > 0) {

    /*OUTPUT THE ENTRY DATA BY KEY, PRETTY MUCH ALWAYS STARTING AT ZERO*/
    $key = 0;
    while($key < $total) {
        print $entries[$key];
        $key++;
    }

}

Thanks Bobbo!

It didn't work at first, but I changed line "while($key < $total)" to "while($key < $limit)" and it worked.

re: Requesting Help [PHP]

Here's another :

php code


<?php
$data = file_get_contents('data.txt');
$entries = explode('|', $data);

for ($i = 0; $i < count($entries) || $i < 10; $i++)
    echo $entries[$i];

?>

Peer pressure

php code



<?php

$data = array_slice(explode('|', file_get_contents('data.txt')), 0, 10);

foreach ($data as $item){
    echo $item . "<br>";
}
