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.

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.

Not quite completely obvious, but... 



you can un_chunk_split() by:



$long_str = str_replace( "\r\n", "", $chunked_str );

another way to group thousands in a number, which is much simpler, is built into PHP :)

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'.

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.

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;

}

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


?>

>> 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

[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:
