Continued Strings - PHP Function

Hitch · 01-05-2007, 09:08 AM

Hey,

I made this function and posted it at my blog, so, i thought i may aswell post it here too.

This is a simple functions to cut strings down to "My lastest project...", from " "My lastest project is a CMS".

Great for "Last Post" colums, descriptions, titles etc....

The code

PHP Code:

  <?php

/*************************************

/ Function Name: Continued Strings

/ Function Description: This cuts a string, and adds a pattern to the end. (User defined patterns, and length)

/ Author: Adrian

/ Website: Dreamit.co.uk

*************************************/

 
function Cont_String($string, $length, $pattern){

 
    if(strlen($string) > $length){

 
    $final = substr("" . $string . "", 0, $length);

    

        $final .= "" . $pattern . "";

 
    return $final;

 
    } else {

 
        return $string;

 
    }

 
}    

 
$about = "Hello, my name is Adrian and i own Dreamit.co.uk";

    $display = Cont_String($about, 21, "...");

 
echo $display;

 
?>

You can choose what "pattern" to display, most common one is "...", remember, when adding the pattern into the function surround the pattern with " ", otherwise you could get errors.

If you decide to cut strings at 21 characters, if the string is below that, no pattern will be added.

I hope you find this useful when adding it into your scripts and projects, it's a general thing that gets left out alof of scripts alot of the time, but is very useful.

Pretty useful Hitch, but it could be cut down a bit

????: NamePros.com http://www.namepros.com/showthread.php?t=277330

PHP Code:

  function Cont_String($string, $length, $pattern='...' /* default pattern is ellipse */ ){

 
    if(strlen($string) > $length)

    {

        $string = substr($string, 0, $length) . $pattern;

    }

    

    return $string;

}

Does exactly the same thing only it's a bit more efficient. (removed unneeded quotes, string manipulation is now 1 line and it now modifies the first functiona rgument instead of creating a new one so only need for one return [although return ends the function regardless so not technically needed])

Also the default pattern is an ellipse (...) if one is not supplied like you say in this line:

Quote:

remember, when adding the pattern into the function surround the pattern with " ", otherwise you could get errors.

It just makes sure that if they do not miss the third argument that it will use the default.

Just though I'd add that

Using "" with nothing inside of it does nothing, btw.

Nice

I found this one on php.net a while back and have used it ever since whenever i need something truncated

PHP Code:

  function truncate_string($string, $max_length){

 
    if (strlen($string) > $max_length) {

 
         $string = substr($string,0,$max_length);

 
         $string .= '...';

????: NamePros.com http://www.namepros.com/showthread.php?t=277330
 
    }

    return $string;

 
}

Slightly less options for the suffix, but works fine for me

Wow, didn't know that was on PHP.net

Looks like they call it "truncate_string", i had to make "Continued Strings" up.

beaver6813, that's the same thing.. just replace "..." with what you want.

I just searched php.net and found this. It makes sure it doesn't cut words apart.

I used either that snippet or another i found on php.net on the Readme Generator i made to limit the lines of the content to make sure it wasn't too long as notepad doesn't automatically terminate lines itself after so many words

And yeah i didn't check whether it was the same, i was just posting the one that i use in my scripts. Whilst we're at it posting examples of terminated lines, this one i used in my readme generator terminates the lines and writes the end product into a text file,

PHP Code:

  function preserve_wordwrap($tstr, $filename, $len = 80, $br = '

????: NamePros.com http://www.namepros.com/showthread.php?t=277330
') {

????: NamePros.com http://www.namepros.com/showthread.php?t=277330
     $strs = explode($br,$tstr);

     $retstr = "";

     foreach ($strs as $str) {

         $retstr .= wordwrap($str,$len,$br) . $br;

     }

$somecontent = $retstr;

 
   if (!$handle = fopen($filename, 'a')) {

         echo "Cannot open file ($filename)";

         exit;

   }

 
 
   if (fwrite($handle, $somecontent) === FALSE) {

       echo "Cannot write to file ($filename)";

       exit;

   }

   fclose($handle);

   return $retstr;

}

But anyways, Hitch bravo on not being lazy and making your own function
