String Qustion

[Mateobus]

Ok I want to take a long string that is 100's of words and make a new string from it that is the first 15 words of that string. Is there an existing function that does this, if so it would look like this.

$string = "Hello my name is joe and I am great";

$smallstring = function($string, 3);

echo $smallstring;

Displays:

Hello my name

Here is one way..

[code]
<?php
$MyString = "This is a test, test testy test woo! test!";

function TrimStr($String, $Limit){
    $StringArr = explode(" ", $String);
    for($i=0; $i <= $Limit-1; $i++){
        $TrimStr .= $StringArr[$i] ." ";
    }
    return $TrimStr;
}

$ShortString = TrimStr($MyString, 3);

echo $ShortString;
?>
[/code]
