Splitting a text String

[larry2004]

Hi All,

I'm trying to split a text string of 250 chars length into 50 char chunks. I know this part is easy, however i want to split the string at the nearest available space either side of 50 chars so as not to truncate a word.

Can anyone help please.

Thanks

Hi,

The code below has not been tested, and there might be a smoother/better way to do it.

<?php

// I assume that your string is stored in $string.

$chunks = array('');
$current = 0;

$words = explode(' ', $string);

for( $b = 0; $b < sizeof($words); $b++ )
{
  $chunks[$current] .= $words[$b].' ';
  
  if( strlen($chunks[$current]) >= 50 )
    $chunks[++$current] = '';
}

?>

Yours, Erik.

Hi eirk,

thanks for getting back to me so quick, im having a problem with the example.

I get an unexpected T_variable for the following line:

**$chunks[$current] .= $words[$b].' ';

Sorry to be a pain, can you help?

Cheers

Hi,

That is strange... I tried the code on my local machine just now, and it worked as it was supposed to.
Could you post your full code here?

Yours, Erik.

<?php

$string = 'this is a test to see if the script works and splits the text accordingly after 50 chars';

$chunks = array('');
$current = 0;

$words = explode(' ', $string);

for( $b = 0; $b < sizeof($words); $b++ )
{
$chunks[$current] .= $words[$b].' ';

if( strlen($chunks[$current]) >= 50 )
$chunks[++$current] = '';
}

?>

Hi,

That makes two of us. Which PHP version are you using?

Yours, Erik.
