Am I Missing Something? Array values are not displaying?

I wonder if it's an issue of syntax somewhere. The code renders and outputs ok, but the php array values don't.

function convert_ad_code($text) {
        include 'file that has ad_randoms, ad_title, and ad_body arrays';

	$output = '';
	
	$ad_var = "<div class='adv_div'>";
	
	for ($tempIncVar = 0; $tempIncVar < 5; $tempIncVar++){
		$ad_var = $ad_var . "<b>" . $ad_title[$ad_randoms[$tempIncVar]] . "</b><br>" . $ad_body[$ad_randoms[$tempIncVar]] . "<br><br>";
	}

	$ad_var = $ad_var . "</div>";
	
	$output = str_replace("###replaceme###",$ad_var,$text);
	
	return $output;
}

Code (markup):

It ends up returning this:

<div class="adv_div">
<b></b><br><span></span><br><br>
<b></b><br><span></span><br><br>
<b></b><br><span></span><br><br>
<b></b><br><span></span><br><br>
<b></b><br><span></span><br><br>
</div>

Code (markup):

The array values never get shown I know that the include file is working, after working through a few errors, so the arrays are there.. I just don't know what I'm doing wrong regarding getting them to output.

Any ideas?

 

What are $ad_title and $ad_randoms? Are you sure that the values in $ad_randoms are not crossing the array index boundary? Are you sure that $ad_title is defined?

 

Try using print_r($ad_title); to see if there is anything at all in the variable.

 

$ad_title[$ad_randoms[$tempIncVar]]

is $ad_randoms[$tempIncVar] an array inside of ad_title, or is it a 3d array which would be like $ad_title[$ad_randoms][$tempIncBar]. Its hard to tell without seeing the included file.
