I have just made the update and that functions correctly now. [:)]
Another question.
You think that it is possible to obtain a short content ?
And also to delete the paragraphs ?
For example:
Duis pede enim, aliquet ac, luctus nec, aliquet a, lorem.
Aenean ultrices sem fermentum velit. Nam nisi enim, posuere at, suscipit eu, rutrum eu, diam.
Praesent a enim eget nulla condimentum viverra. Nunc diam dolor, ultrices in, commodo ut, dictum consectetuer, nisi. Mauris dolor lorem, nonummy mollis, blandit non, fringilla blandit, nulla.
Mauris nec nibh eu purus semper ullamcorper. Ut quis ipsum. Donec sagittis mattis velit. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Aenean semper velit. Sed tincidunt auctor diam. Vivamus in massa.
For:
Duis pede enim, aliquet ac, luctus nec, aliquet a, lorem. Aenean ultrices sem fermentum velit. Nam nisi enim, posuere at, suscipit eu, rutrum eu, diam. Praesent a enim eget nulla condimentum viverra. ...

Yes, it's a PHP question. Here's a function that removes all the html tags, then returns the first NNN number of words:
// remove all tags and reutnr first NNN words of content
function getTextSummary($value, $maxWords = 25) {
$textOnly = strip_tags($value);
$words = preg_split("/\s+/", $textOnly);
$words = array_splice($words, 0, $maxWords);
$summary = join(" ", $words);
return $summary;
}It defaults to returning 25 words and you can change the default above or specify how many words you want. Like this:
$myValue = "Aenean ultrices sem fermentum velit. Nam
nisi enim, posuere at, suscipit eu, rutrum eu, diam.
Praesent a enim eget nulla condimentum viverra. Nunc diam
dolor, ultrices in, commodo ut, dictum consectetuer, nisi.
Mauris dolor lorem, nonummy mollis, blandit non, fringilla
blandit, nulla. ";
print getTextSummary($myValue); // returns 25 words
print getTextSummary($myValue, 6); // returns 6 wordsLet me know if that works for you.

But, it is possible to obtain : $myValue = "$record['content']";
Thank you for your assistance.

In the table, the return to the line (<br />) gives attached words.
For example :
Aenean ultrices sem<br />fermentum velit.<br />Nam nisi enim,<br />posuere at, suscipit<br />eu, rutrum eu, diam.
give :
Aenean ultrices semfermentum velit.Nam nisi enim,posuere at, suscipiteu, rutrum eu, diam.

When you see the @ symbol in front of something in PHP if means "don't show errors for that". So sometimes we'll use @$record['content'] so that if $record['content'] isn't defined we won't get a "undefined variable" warning message displayed on the screen by PHP.
Here's an updated function the replaces tags with a space when it removes them so the words don't get joined together.
// remove all tags and reutnr first NNN words of content
function getTextSummary($value, $maxWords = 25) {
$textOnly = preg_replace("/<(.*?)>/s", " ", $value); // strip tags
$words = preg_split("/\s+/", $textOnly);
$words = array_splice($words, 0, $maxWords);
$summary = join(" ", $words);
return $summary;

I also added to the end : print(" ...");
<?php
$record['content'];
print getTextSummary($record['content'], 40); // returns 25 words
print (" ...");
?>
