[SOLVED] PHP "condense" Text

[Vivid Lust]

Hey all,

 

Could someone tell me how in PHP, I could turn a whole paragraph into X amount of words??

 

Thanks for any help.

substr is one way...explode would have to be another.

Could you be a little more descriptive?

 

How would you like to do this?  Cut off the end of the paragraph after a certain amount of words?

 

You could just explode the paragraph and only keep the first x amount of words...  but again, need more detail.

What im doing, is getting a forum post, I want to limit it to X words, so its a kind of excerpt.

Get the length with strlen, if its longer than you want, chop it off with substr

Thanks for the help, however im finding it hard to use substr.

 

Could some please post me the code, so that I can turn:

 

"With Quick-Reply you can write a post when viewing a topic without loading a new page. You can still use bulletin board code and smileys as you would in a normal post."

 

Into: "With Quick-Reply you can write"

 

There the code limits the paragraph to the first 5 words.

 

Thanks all.

* Not tested * - This SHOULD echo the first 4 words of the string.

 

$string = "With Quick-Reply you can write a post when viewing a topic without loading a new page. You can still use bulletin board code and smileys as you would in a normal post."

$short = "";
$pieces = explode(" ", $string);
for($i = 0; $i $short .= $pieces[$i] . " ";

echo $short;

This is assuming you want it to be cut into 10 words, roughly 50 characters:

 

<?php
$text = "With Quick-Reply you can write a post when viewing a topic without loading a new page. You can still use bulletin board code and smileys as you would in a normal post.";

if (strlen($text) > 50) {
    $chopped = substr($text, 0, 50);
    echo $chopped . "...";
}else {
    echo $text;
}
?>

 

Simple as that.

 

Should do it.

 

 

EDIT:

This is an example using substr
