PHP: chunk_split

Beschreibung

string chunk_split ( string body [, int chunklen [, string end]] )

Kann für die Aufteilung eines Strings in kleinere Stücke verwendet werden. Dies ist z.B. hilfreich bei der Umwandlung von base64_encode()-Ausgaben, die RFC 2045 entsprechen müssen. Die Funktion fügt die in end angegebene Zeichenkette (standardmäßig "\r\n") nach jeweils chunklen Zeichen (Vorgabewert 76 Zeichen) in den ursprünglichen String ein. Zurückgegeben wird der veränderte String, die ursprüngliche Zeichenkette bleibt unverändert.
Beispiel 1. chunk_split() Beispiel

<?php // formatiert $data unter Beachtung von RFC 2045 $neuer_string = chunk_split(base64_encode($data)); ?>

Siehe auch str_split(), explode(), split(), wordwrap() und RFC 2045.

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:
