An alternative for unicode strings;

<?php
function chunk_split_unicode($str, $l = 76, $e = "\r\n") {
   
$tmp = array_chunk(
       
preg_split("//u", $str, -1, PREG_SPLIT_NO_EMPTY), $l);
   
$str = "";
    foreach (
$tmp as $t) {
       
$str .= join("", $t) . $e;
    }
    return
$str;
}

$str = "Yarım kilo çay, yarım kilo şeker";
echo
chunk_split($str, 4) ."\n";
echo
chunk_split_unicode($str, 4);
?>

If you are using UTF-8 charset you will face a problem with Arabic language
to solve this problem i used this function

<?php
function chunk_split_($text,$length,$string_end)
{
   
$text = iconv("UTF-8","windows-1256",$text);
   
$text = str_split($text);
    foreach(
$text as $val)
    {
        if(
$a !== $val)
        {
           
$a = $val;
           
$x = 0;
        }else{
           
$a = $val;
           
$x++;
        }
        if(
$x > $length)
        {
           
$new_text .= $val.$string_end;
           
$x = 0;
        }else
        {
            
$new_text .= $val;
        }
       
    }
   
$new_text = iconv("windows-1256","UTF-8",$new_text);
    return
$new_text;
}
?>

Oops. Here is a correction for the post below.

<?php

function mbStringToArray ($str) {
    if (empty(
$str)) return false;
   
$len = mb_strlen($str);
   
$array = array();
    for (
$i = 0; $i < $len; $i++) {
       
$array[] = mb_substr($str, $i, 1);
    }
    return
$array;
}

function
mb_chunk_split($str, $len, $glue) {
    if (empty(
$str)) return false;
   
$array = mbStringToArray ($str);
   
$n = -1;
   
$new = '';
    foreach (
$array as $char) {
       
$n++;
        if (
$n < $len) $new .= $char;
        elseif (
$n == $len) {
           
$new .= $glue . $char;
           
$n = 0;
        }
    }
    return
$new;
}

// DEMO:
$str = '一二一二一二一二一二';
echo
mb_chunk_split($str, 2, '*<br />');

// produces this output:
一二*
一二*
一二*
一二*
一二

chunk_split() is not multibyte safe. If you ever run into needing the function that is multibyte safe, here you go:

<?php

function mbStringToArray ($str) {
    if (empty(
$str)) return false;
   
$len = mb_strlen($str);
   
$array = array();
    for (
$i = 0; $i < $len; $i++) {
       
$array[] = mb_substr($str, $i, 1);
    }
    return
$array;
}

function
mb_chunk_split($str, $len, $glue) {
    if (empty(
$str)) return false;
   
$array = mbStringToArray ($str);
   
$n = 0;
   
$new = '';
    foreach (
$array as $char) {
        if (
$n < $len) $new .= $char;
        elseif (
$n == $len) {
           
$new .= $glue . $char;
           
$n = 0;
        }
       
$n++;
    }
    return
$new;
}

I've found this quite useful for simulating various kinds of shuffles with cards.  It is humorous but can imitate multiple deck cuts and other (imperfectly) random events.

<?php
function truffle_shuffle($body, $chunklen = 76, $end = "\r\n")
{
    
$chunk = chunk_split($body, $chunklen, "-=blender=-");
    
$truffle = explode("-=blender=-",$chunk);
    
$shuffle = shuffle($truffle);
    
$huknc = implode($end,$shuffle);
     return
$huknc;
}
?>

I think this is better, since you can still use the ampersand in your text:

<?php
function HtmlEntitySafeSplit($html,$size,$delim)
{
 
$pos=0;
  for(
$i=0;$i<strlen($html);$i++)
  {
    if(
$pos >= $size && !$unsafe)
    {
     
$out.=$delim;
     
$unsafe=0;
     
$pos=0;
    }
   
$c=substr($html,$i,1);
    if(
$c == "&")
     
$unsafe=1;
    elseif(
$c == ";")
     
$unsafe=0;
    elseif(
$c == " ")
     
$unsafe=0;
   
$out.=$c;
   
$pos++;
  }
  return
$out;
}
?>

"version" of chunk_split for cyrillic characters in UTF-8

public function UTFChunk($Text,$Len = 10,$End = "\r\n")
{
    if(mb_detect_encoding($Text) == "UTF-8")
    {
        return mb_convert_encoding(
                chunk_split(
                    mb_convert_encoding($Text, "KOI8-R","UTF-8"), $Len,$End
                ),
                "UTF-8", "KOI8-R"
            );
    } else
    {
        return chunk_split($Text,$Len,$End);
    }
}

this is example for russian language

Here's a version of Chunk Split I wrote that will not split html entities. Useful if you need to inject something in html (in my case, <wbr/> tags to allow for long text wrapping).

<?php
function HtmlEntitySafeSplit($html,$size,$delim)
{
 
$pos=0;
  for(
$i=0;$i<strlen($html);$i++)
  {
    if(
$pos >= $size && !$unsafe)
    {
     
$out.=$delim;
     
$unsafe=0;
     
$pos=0;
    }
   
$c=substr($html,$i,1);
    if(
$c == "&")
     
$unsafe=1;
    elseif(
$c == ";")
     
$unsafe=0;
   
$out.=$c;
   
$pos++;
  }
  return
$out;
}
?>

This function works well to cut long para for preview without cutting word. Good for Unicode such as &#7789;

function split_hjms_chars($xstr, $xlenint, $xlaststr)
{
    $xlenint = strpos($xstr," ",$xlenint);
   return substr($xstr,0,$xlenint).$xlaststr;
}

When using ssmtp for simple command line mailing:

$mail_to = "destination@emailbox.com";
$msg = "this would be an actual base64_encoded gzip msg";
$date = date(r);
$mail  = "X-FROM: root@sender.org \n";
$mail .= "X-TO: ".$mail_to. " \n";
$mail .= "To: ".$mail_to. " \n";
$mail .= "Date: $date \n";
$mail .= "From: root@sender.org \n";
$mail .= "Subject: lifecheck \n";
$mail .= $msg." \n";
exec("echo '$mail' | /usr/sbin/ssmtp ".$mail_to);

be sure to invoke chunk_split() on your message body - ssmtp becomes unhappy with long lines and will subsequently trash  your message.

in response to "hansvane at yahoo dot com dot ar"

you can do that ALOT easier:

<?php
function split_hjms_chars($xstr, $xlenint, $xlaststr)
{
   return
substr($xstr,0,$xlenint).$xlaststr;
}
?>
hansvane at yahoo dot com dot ar 21-Jan-2007 11:06
This function is very simple and many other functions make this on PHP 5 and even some ones in 4 the good think about this one is that work on php 3.0.6 and 4

function split_hjms_chars($xstr, $xlenint, $xlaststr)
{
    $texttoshow = chunk_split($xstr,$xlenint,"\r\n");
    $texttoshow  = split("\r\n",$texttoshow);
    $texttoshow = $texttoshow[0].$xlaststr;
    return $texttoshow;
}

// For use

echo split_hjms_chars("This is your text",6,"...");

// Will return

This i...

It is useful to cut long text on preview lists and if the server it's old.

Hope it helps some one. Hans Svane

I'm not sure what versions this also occurs in but the output of chunk_split() in PHP 5.0.4 does not match the output in other versions of PHP.

In all versions of PHP I have used, apart from 5.0.4 chunk_split() adds the separator (\r\n) to the end of the string.  But in PHP 5.0.4 this does not happen.  This had a fairly serious impact on a library I maintain so it may also affect others who are not aware of this.
xamine at gmail dot com 04-Jun-2006 01:06
In reply to "adrian at zhp dot inet dot pl" digit grouping function:
<?php
    $number
= strrev(chunk_split (strrev($number), 3,' '));
   
//If $number is '1234567', result is '1 234 567'.
?>

There is a much more simple way of doing this, by using the built-in number_format() function.

<?php
   $number
= number_format($number,2,"."," ");

  
//This will round $number to 2 decimals, use the dot (".")
   //as decimal point, and the space (" ") as thousand sepparator.

?>
kevin @t hyguard,com 03-Oct-2005 09:08
Not quite completely obvious, but...

you can un_chunk_split() by:

$long_str = str_replace( "\r\n", "", $chunked_str );
harish at thespitbox dot net 30-Jul-2005 07:45
another way to group thousands in a number, which is much simpler, is built into PHP :)

www.php.net/number_format
adrian at zhp dot inet dot pl 08-Jul-2005 04:28
If you need to output number formated with thousand's separator, just use it:

$number = strrev(chunk_split (strrev($number), 3,' '));

If $number is '1234567', result is '1 234 567'.
Kevin 25-Jun-2005 06:10
To phpkid:

This is a much simpler solution.

<?php
function longWordWrap($string) {
   
$string = str_replace("\n", "\n ", $string); // add a space after newline characters, so that 2 words only seperated by \n are not considered as 1 word
   
$words = explode(" ", $string); // now split by space
   
foreach ($words as $word) {
       
$outstring .= chunk_split($word, 12, " ") . " ";
    }
    return
$outstring;
}
?>

@phpkid:

You can avoid such long complex code and just use some CSS stuff.

Just add style="table-layout:fixed" in your <td > tag and your problem will be solved.

ciao
phpkid 28-May-2005 12:47
Well I have been having issues with a shoutbox I am coding it would keep expanding the <TD> if there were large words in it but I fixed it with this:

function PadString($String){
    $Exploded = explode(" ", $String);
    $Max_Parts = count($Exploded);
   
    $CurArray = 0;
    $OutString = '';
    while($CurArray<=$Max_Parts)
    {
        $Peice_Size = strlen($Exploded[$CurArray]);
        if($Peice_Size>15)
        {
            $OutString .= chunk_split($Exploded[$CurArray], 12, " ");
            $CurArray++;
        } else {
            $OutString .= " ".$Exploded[$CurArray];
            $CurArray++;
        }
    }
   
    return $OutString;
}
mv@NOSPAM 24-Jan-2004 08:39
the best way to solve the problem with the last string added by chunk_split() is:

<?php
$string
= '1234';
substr(chunk_split($string, 2, ':'), 0, -1);
// will return 12:34
?>
Danilo 10-Dec-2003 03:51
>> chunk_split will also add the break _after_ the last occurence.

this should be not the problem

substr(chunk_split('FF99FF', 2, ':'),0,8);
will return FF:99:FF
sbarnum at pointsystems dot com 20-Apr-2001 09:46
[Editor's note: You can always use wordwrap('FF99FF', 2, ':', 2); to avoid this]

chunk_split will also add the break _after_ the last occurence.  So, attempting to split a color into base components,
chunk_split('FF99FF', 2, ':');
will return FF:99:FF:
