Limiting text display

[rulian]

Lets say I have a text blob that I only want to display particially, how woud I do that, example:

$textblob="the blah of blah blah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blahblah blah";

will only show up as :
"The blah of blah blah blah blah....."

Try this command:

$subs = substr($textblob,0,20);
/ this will separate the 20 first carachters from position 0 /

print $subs."...";
