shorten product description

[SpecTech]

Ok I am trying to make a shortend down version of a product description to put on my sections. So far I have this.

<actinic:block php="true" >
$desc = '<actinic:variable encoding="perl" name="ProductDescription" selectable="false" />';
  
$desc1 = substr($desc, 3,150);

echo "$desc1....";

  
</actinic:block>

this works fine and generated 150 letters however it never finishes on the last word it finishes half way through a word. Does anyone know how I can make it finish off the word then end


Solution,

<actinic:block php="true" >
$desc = '<actinic:variable encoding="perl" name="ProductDescription" selectable="false" />';
  
$desc1 = explode(substr($desc, 3,150));

echo "$desc1....";

  
</actinic:block>

Explode it!

Find the position of the next or previous space (whitespace) in the string from 180 characters onwards and use everything to the left of that position.
