Limiting the number of words displayed

[darylh]

I have a news script and I want to have a summary of a the article displayed on another page. The code is:

<?php
include '/path/to/news/news.php';
if (!$disp) {
$disp = 4; // default # of news entries
}
$whatsnew = new digiNews($disp);
echo $whatsnew->entries;
?>

How could I ammend this to display 30 words and the three dots [...] at the end?

Some would use ereg or some such, but this is much simpler: If you have a variable that has the text of your article, say, $text, you could do this:

$words = explode(" ",$text);

for($i = 0; $i < 30; $i++) {
&nbsp;&nbsp;&nbsp;$summary .= $words[$i] . " ";
}

$summary .= "...";

print($summary);
