[xbl12]

Hi;
if i got some strings as following

str1="asdfghjjjjjkkk";
str2="jhdkjfhaskjhfdkjsahdfhasfsdfdk.....";
str3="gf";

then i want the above just keep the first front 3 letters and then add the ".." to the end of the string

str1="asd..";
str2="jhd..";
str3="gf";

Would any one tell me how i can do that, please, Thanks

You can use the substr() function to cut out as many characters as you need.

$str1="asdfghjjjjjkkk";
$str2="jhdkjfhaskjhfdkjsahdfhasfsdfdk.....";
$str3="gf";


$newsub1=substr($str1,0,3) . "...";
$newsub2=substr($str2,0,3) . "...";
$newsub3=substr($str3,0,3) . "...";

You can use an If statement to check the string and see if it has less than 3 characters so you don't add the trailing "...";

You would run strlen() on your string to determine it's length. If the length exceeds 3 letters, you would substr($str, 0, 3) to cut off the string past the 3rd letter. Finally, you would concatenate the resulted cut string with a string of "..".

Even though it's solved, I guess your using this for a loop which generates links or shortened text?

If so, what about making a function?

function genShortText($text, $len=3, $appendText="", $preText="") {
if (strlen($text)>$len) {
  $retText = $preText . substr($text, 0,$len) . $appendText;
  }
else {
  $retText = $preText . $text . $appendText;
 }
}

echo genShortText("hello there", 3, "", "...");
echo genShortText("hello there", 4, "", "...");
echo genShortText("hello there", 20,"", "...");
echo genShortText("hello there", 3, "", "");
echo genShortText("hello there", 3, "", "...");
echo genShortText("hello there", 3, '<a href="#">, "</a>");

ps. I didnt test the code, so it's to be used as psuedo.. (just wrote it in this reply)

sorry, lol.. you have to add return $retText; after the else {} is closed (within the function).
