PHP : Function Reference : String Functions : chunk_split

chunk_split

Split a string into smaller chunks (PHP 4, PHP 5)
string chunk_split ( string body [, int chunklen [, string end]] )

Example 2398. chunk_split() example

<?php
// format $data using RFC 2045 semantics
$new_string = chunk_split(base64_encode($data));
?>

Code Examples / Notes » chunk_split

sbarnum

[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:

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.

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;
}

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;
}
?>

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;
}


hansvane

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


mv@nospam

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
?>

Not quite completely obvious, but...
you can un_chunk_split() by:
$long_str = str_replace( "\r\n", "", $chunked_str );

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;
}
?>

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.
?>


adrian

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'.

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.


harish

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

@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.

>> 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
