a little help with a code for ads

Hi,
I was wondering if someone could help me with a code by showing an example. I have a site with tons of articles on it and I want to have ads appear in mid article, kind of like news websites do. Someone told me I could use explode to find all the instances of </P> so I know where the end of each paragraph lies. The idea is to insert a paragraph with an adcode in it after say the third or fourth paragraph. I'm not really sure how to count the number of times </p> shows up and how to choose say the fourth time to insert my adcode.

I'm kind of a newbie. That's why I asked for an example because then I could pick it apart and learn by example. Hope someone can show me the way.

Thanks/

I'm sure there are tutorials about how to do this kind of thing. Have you run a google search for it and looked around php tutorial sites? After you've done that I'm sure you'll find similar things at the very least. Use that and give it a go then ask us specific questions since its unlikely anyone here will just write your code for you.

Thanks for the reply. I guess I was getting hopeful that someone might write code for me. I did search google and go through numerous tutorials before posting here. I've tried really hard to get the desired result on my own but there are a lot of concepts I haven't grasped yet.

I have come up with the following code I learned from an example:

PHP Code:


		
			
// The Text phrases to split

$text = "$articletext";



// Call the Function Explode and Set it to a variable, Telling the explode function by what charecter to seperate it, and what text to seperate

$ExplodeIt = explode("</p>","$text");



// Lets get a Count Of the total Values in the array.



$Count = count($ExplodeIt);



// Create a Loop to Output the Information. Make sure $i starts off at 0, this is where the first value is returned

for ($i=0; $i < $Count; $i++) {



// Output the Information. Remember, It is looping so as many items that are in the array will do this loop that many times.

echo "<p><ad code goes here> $ExplodeIt[$i]</P>";



}

What this does is place the ad code after each paragraph. The looping has me confused. What expression shoul I be looking for to get the adcode to appear only once, and after a </P> of my choice? I don't mind trying to figure it out myself, but a push in the right direction would be greatly apreciated.

Good work, only a small change to get what you want in there -

PHP Code:


		
			
// which paragraph to output under (3 in this example)

$ad_paragraph = 3;



// The Text phrases to split 

$text = "$articletext"; 



// Call the Function Explode and Set it to a variable, Telling the explode function by what charecter to seperate it, and what text to seperate 

$ExplodeIt = explode("</p>","$text"); 



// Lets get a Count Of the total Values in the array. 



$Count = count($ExplodeIt); 



// Create a Loop to Output the Information. Make sure $i starts off at 0, this is where the first value is returned 

for ($i=0; $i < $Count; $i++) { 



// Output the Information. Remember, It is looping so as many items that are in the array will do this loop that many times. 

  if ($i == $ad_paragraph)

    echo "<p><ad code goes here> $ExplodeIt[$i]</P>";

  else

    echo "<p>$ExplodeIt[$i]</P>";

}

Hope this helps,

-KM-

Cool. After banging my head against the wall for a while I came up with something that works as well. I wanted to post it here then saw your reply. I was wondering which is more efficient, my code or yours?

PHP Code:


		
			
// The Text phrases to split

   $text = "$articletext";



// Call the Function Explode and Set it to a variable, Telling the explode function by what character to seperate it, and what text to seperate

   $ExplodeIt = explode("</p>","$text");



// Lets get a Count Of the total Values in the array.

   $Count = count($ExplodeIt);



// Create a Loop to Output the Information. Make sure $i starts off at 0, this is where the first value is returned

   for ($i=0; $i < $Count; $i++) {



// Output the Information. Remember, It is looping so as many items that are in the array will do this loop that many times.

   echo "$ExplodeIt[$i]";

     if ($i == 2) {

       echo("<P>&nbsp;");

       include("my_adcode");

       echo("&nbsp;</p>");       

       }

   }
