[SOLVED] exploding after 3 occurances

[swamp]

Hey, I'm exploding $post into paragraphs to then go in divs... My paragraphs are seperated with < br / > tags.

 

           <?php

$spliter  = nl2br($post);
$out = explode("<br />", $spliter);

?>

 

I need it to only explode it after 3 occurances, so first if I had:

 

Hello<br />My name<br />is<br />Swamp<br />I need help<br />with this script  

 

So if i echoed $out[1] it would look like:

 

Hello

My name

is

 

and $out[2] would be:

 

Swamp

I need help

with this script.

 

Cheers!

          <?php

 

$spliter  = nl2br($post);

$out = explode("<br />", $spliter);

 

 

 

$first=$out[0]."br ".$out[1]."br ".$out[2]."br ".;

$second=$out[3]."br ".$out[4]."br ".$out[5]."br ".;

 

?>

 

i think is working the same way as you need

[sasa]

try

<?php
$text = 'Hello<br />My name<br />is<br />Swamp<br />I need help<br />with this script';
$text = explode('<br />',$text);
$text =array_chunk($text, 3);
foreach ($text As $k => $v) $text[$k] = implode('<br />', $v);
print_r($text);
?>

Cheap way is to explode it, shift off the first three if their not null, then join them with <br />

thanks, I'm trying to get yours to work sasa, but I'm not too sure how to implement it with my script.

 

This is the whole thing:

 

           <?php
$spliter  = nl2br($post);
$out= explode(".<br />", $spliter);

?>

<?
foreach($out as $k=>$v)

{
//echo '<div id="content_'.$k.'">'.$v

?>

<div id="content_<? echo $k ?>">
<p>
<? echo $v ?>.
    </p>
    <p>
   

<? //if first div then don't put previous button
if ( $k == 0 ) {
echo " ";
} else {
 ?>  <span class="arrow-back"><a href="#" onClick="setVisible('content_<? echo $k -1; ?>');">previous page</a></span>
<? } ?>


  <?  //if last div don't put next button
  $paragraphs = count($out); //count paragraphs
if ( $k ==  $paragraphs -1 ) {
echo " ";
} else {
 ?>  <span class="arrow"><a href="#" onClick="setVisible('content_<? echo $k +1; ?>');">next page</a></span>
<? } ?>

</p>
</div>

<? 

}

?>

If you wanted to do it this way, you could... doesn't deal with arrays.

 

It's very basic, but it accomplishes what you're looking for.

 

<?php
$string='This is the first.<br />This is the second.<br />This is the third.';
$string=str_replace('<br />','</div><div>',$string);
$string.='<div>'.$string;
$string.=$string.'</div>';
?>

... no it doesn't. they're trying to group every three br-delimited sections together. this code simply switches br for <div> containers.

Yeah, sorry Jabop but thats not the thing I'm looking for.

 

Has anyone got any further advice on this? It would be very much appreciated

sasa's code will do what you're looking for:

 

<?php
$text = 'Hello<br />My name<br />is<br />Swamp<br />I need help<br />with this script';
$text = explode('<br />',$text);
$text =array_chunk($text, 3);
foreach ($text As $k => $v) $text[$k] = implode('<br />', $v);

foreach ($text AS $k => $chunk)
{
  echo '<div id="content_'.$k.'">'.$chunk.'</div>';
}
?>
