Crop Content

Hello, this snippet crops the content and puts "..." to the end. My question is, how can I get the rest of the content ?

<?

$str = "Yeah, but on my website, before I realized that converting quotes, etc, to entities was a bad idea, I already had a lot of stuff put into a database...Also, symbols like show up as question marks... and I don't really know how to fix that. In my four years of HTML experience, and two years of PHP experience, I've never been able to get character encoding to do what I want it to.";

$chars = "150";

function shortText($str, $chars)
{
if (strlen($str) > $chars)
    {
    $str = substr($str, 0, $chars);
    $str = $str . "...";
    return $str;
    }
else
    {
return $str;
    }
}

echo shortText($str, $chars);

?>

PHP:

 

You mean the text which was leftout during the crop? Then something like this;

$rest = substr($str, $chars, strlen($str));

PHP:

 

Limit Characters From Your Text

 

I just want to get the section which starts with "..." (script does this after 150 chars) and finishes at the end.

 

I don't get you, you want the text before the '...'? Then I assume you don't understand PHP?

$str = substr($str, 0, $chars); //<----- This is the text before '...'
    $str = $str . "...";
    return $str;

PHP:

 

No man, I want the section which is after "..."

 

Can you please explain it clearly? From your previous posts I've understood either;
- Get the text which is removed (which is supposed to be after ...)
- Get the text before ... (which is already in the script)

 

The first one is what I want. Does your code do that ? (http://forums.digitalpoint.com/showpost.php?p=13358660&postcount=2)

 

Yep Gets the removed text.

 

Okay thank you . Sorry for my bad english, I am not english.

 

Here you go:

I've modified your function, so if you set $show too 1 it will display the text from the defined character, if set to 0 it will just function as before (limit the text and add ...):

<?php
  function shortText($str, $chars, $show)
    {
      if (strlen($str) > $chars)
        {
          $str2 = substr($str, $chars);
          $str = substr($str, 0, $chars);
          $str = $str . "...";
          
          if ($show == "1")
            {
              echo $str2;
            }
          else
            {
              return $str;
            }
        }
      else
        {
          return $str;
        }
    }


$text = <<<TEXT

TEXT;

$length = "150";

//0 = don't show the text after the $length (150? characters)
//1 = show the text after $length (150? characters)
echo shortText($text, $length, "0");

?>

Thanks danx. This snippet is nice, too.
