Showing a message based on number of words

Hi,

I've got $r['fulldescription'] which stores a long bit of text. Basically I wan't to show two ad blocks in that text.

I need to show an adblock every 250 words but limit the amount of adblocks to 2.

Anyone got any ideas, thanks!

 

.. Anyone? thanks

 

If I understood you right, then you should use substr();
It helps you to limit the words.
substr($string,0, number of letters);

 

I don't want to limit the words, I wanna show something every certain amount of words.

 

Try this code. It's pretty inefficient, but it does the job.

<?php

	$string = 'This is a test string with some words in it';
	$Advert = '{ad}';
	$Frequency = 4;
	$WordCounter = 1;
	
	$WordArray = explode( ' ', $string );
	
	for ( $count = 0 ; $count <= sizeof( $WordArray )-1 ; $count++ )
	{
		echo $WordArray[ $count ] . ' ';
		
		if ( $WordCounter++ == $Frequency )
		{
			$WordCounter = 1;
			echo $Advert;
		}
	}

?>

Thanks Brewster, I'll try it tomorrow hopefully. I'm off now, cheers.

 

<?php
$string = '';
$advert = '';

function insert_ads($string,$advert)
{
   $arr = explode(" ",$string);
   if(count($arr) >= 250)
   {
      $arr[249] =  $arr[249].$advert;
   }

   if(count($arr) >= 500)
   {
      $arr[499] =  $arr[499].$advert;
   }
   return implode(" ", $arr)
}

echo insert_ads($string,$advert);

?>

Not sure if it is the best way, but this is something I would use to do what your asking.
