limited list from txt

hi,
I am just a beginner in PHP. I am using the script from one of the tutorials to get my news-items from a text file.

==================
<?PHP
$data = file('news.txt');
$data = array_reverse($data);
foreach($data as $element) {
$element = trim($element);
$pieces = explode("|", $element);

echo $pieces[0] . ": " . $pieces[1] . "<BR>";
}
?>
==================

How can I limit the list to the last 5 items???

Paul

Just count them

php Code:

Original - php Code
<?PHP $data = file('news.txt'); $data = array_reverse($data); $i = 0; while ( $i < 5 ) { $element = $data[$i++]; $element = trim($element); $pieces = explode("\|", $element); echo $pieces[0] . ": " . $pieces[1] . "<BR>"; } ?>

 
<?PHP
$data = file('news.txt');
$data = array_reverse($data);
$i = 0;
while ( $i < 5 ) {
$element = $data[$i++];
$element = trim($element);
$pieces = explode("|", $element);
 
echo $pieces[0] . ": " . $pieces[1] . "<BR>";
}
?>

ShaneO : I had been didactic

For myself, I'll probably wrote something like

php Code:

Original - php Code
<?PHP $data = array_reverse( file('news.txt') ); $i = 0; while ( $i < 5 ) { $pieces = explode("\|", $data[$i++]); echo $pieces[0] . ": " . $pieces[1] . "<BR>"; } ?>

 
<?PHP
$data = array_reverse( file('news.txt') );
$i = 0;
while ( $i < 5 ) {
  $pieces = explode("|", $data[$i++]);
  echo $pieces[0] . ": " . $pieces[1] . "<BR>";
}
?>

php Code:

Original - php Code
<?PHP $data = array_reverse( file('news.txt') ); $i = 0; while ( $i < 5 ) { echo preg_replace( Array( "/\|/", "/$/" ), Array( ": ", "<br>" ), $data[$i++] ); } ?>

 
<?PHP
$data = array_reverse( file('news.txt') );
$i = 0;
while ( $i < 5 ) {
  echo preg_replace( Array( "/|/", "/$/" ), Array( ": ", "<br>" ), $data[$i++] );
}
?>

May be on one line ;)

RE: limited list from txt

or simply use array_slice() - that's what it is there for ;)

php Code:

Original - php Code
... $data5=array_slice($data, 0, 5); foreach($data5 as $element) { ...

 
...
$data5=array_slice($data, 0, 5);
foreach($data5 as $element) {
...

if u want to understand this better, go to http://php.net/array_slice
