string display

[hykc]

hi,

I have some text which will return from DB, and I want to limit the string length to display, let say 50 character,
I tried substr($string, 0, 50);
but it may cut in the middle of the word, so I want to make sure it will cut at the space charactor, how can i do it? thanks

I would say do something like this:

$temp = substr($original,0,51);
$lastSpace=strrpos($temp," ");
if($lastSpace===false) {
   $final = substr($temp,0,50);
}
else {
   $final = substr($temp,0,$lastSpace);
}

Good luck!

if($lastSpace===false)

what is "===" meants? or typo?

It's pretty important actually (although not so much in this case).

It helps distinguish between false and 0, because PHP is so type-loose.
