strtok HELP

[robert_gsfame]

Suppose i have this words

 

" I am one of members of PHPFreaks Forum " and i want to make this words into

 

" I am one of members of PHP..." Using strtok

 

then how to do it let say:

 

$words = "I am one of members of PHPFreaks Forum"

then how to break this words with using strtok..if i want to break based on space there i can do it like this

 

  strtok($words, " ");

 

But in this case words will be change to " ... " after reach strlen

 

Can anyone help me

$my_string = "I am one of the members of the PHP Freaks Forum";
$max_length = 50;

if(strlen($my_string) > $max_length){
        echo substr($my_string,0,$max_length)." [...]";
}
else{
        echo $my_string;
}
