Как да направя ограничение на символите

[hackera]

Как да направя ограничение на символите, демек примерно да се показват по 20 букви на тема...?

function textlimit($text, $len) {
if (strlen($text) > $len) {
return substr($text, 0, $len) . "...";
}
else { return $text; }
}

Това?

 

[emagi]

Ето по следния начин:

$text = substr($text, 0, 20);
$text1 = "............";
echo $text.$text1;

може и без послената променлива $text1, тя съдържа само ....... ,с което искам да покаже че това е само извадка.А променливата $text ти съдържа целия текст!
Пример:ако $text = "ADSFAS FASD FASDF FASDF FASD FADSF ASDF ASDF"; ,то след обработката както ти написах при извеждане с echo ще изглежда така:

$text = "ADSFAS FASD FASDF FASDF FASD FADSF ASDF ASDF";
$text = substr($text, 0, 10); 
$text1 = "............"; 
echo $text.$text1;

и резалутата ще е следния(само първите 10 букви):

ADSFAS FASD..........
