How to use teaser in php4

[chrome]

Hello

 

I'm having a difficulty locating a sample script that implements teaser. What I need is to display a specified amount of text on my website from a much larger group of text, then I want it to place a trailing ... [more]. I do not want it to show a partial word when the desire quantity is achieved eg. Imple instead of Implementation.

 

 

Thanks

Well you need to get the data into a string with file_get_contents().

Then shorten it to the appropriate length using substr().

 <?php
$string=file_get_contents($file);
$teaser=substr($string,0,200);
echo $teaser.'...more'; //make this a link
?>

Might look here also. http://www.wljol.com/toh/technical/teasers/index.php

 

I have been moving things around, so the graphics on that page are 'messed-up'; however, the text, example and downloadable zip are all functional

WolfRage, your solution will cutoff words, which the OP said he does not want.  A combo of wordwrap and explode should do the trick:

 

$string = "some really long text";
$string = explode("[TEXTBREAK]",wordwrap($string,110,"[TEXTBREAK]")); // change 110 to whatever amount of chars
$newString = $string[0] . "...<a href='somepage.php'>[more]</a>";

Nicely done Crayon, I had considered that, just felt I was giving him a nudge in the right direction with out presenting a complete solution. I perfer to nudge people along. I think they learn better that way.

Well I guess pointing someone in the right direction by showing him an example of what won't work is one way to do it, though not if you're telling him that's what he needs to do...

Ouch, didn't know we were trading shots.
