function not printing

I don't know if I missed something. The function is not printing at all.

$contents_of_page = file_get_contents('../bible1.html');

preg_match_all("#<td.*>(.+)</td#Ui", $contents_of_page, $tdInnerHTML);
$totaltds = count($tdInnerHTML[1]);
print_r($tdInnerHTML[1]);//prints all TD contents 

/********************************************************************************/
function recValues(){
	$tdValues = array();
	$tdValues = "";
	for($j = 0; $j < $totaltds; $j++){
		if($j % 10 != 0){
			$tdValues .= "'".$tdInnerHTML[1][$j];
			if($j < 9){
				$tdValues .= "', ";
				}else{
				$tdValues .= "'";
				}
			}
		}
	return $tdValues;
	}
	echo "<span style='font-weight: bold;'>hi".recValues()."hi</span><br />\n";

PHP:

 

$totaltds, and $tdInnerHTML do not exist in the scope of recValues()... make them global. Or pass them as parameter.

 

How do you do that? I'm not too familiar in writing functions.

 

Take a look at: www.php.net/global and www.php.net/functions

 

Ok so I moved some things in the function.
But another problem appears.The last $tdValues .= "'".$tdInnerHTML[1][$j]; shouldn't have ,' that follows it. I'm avoiding the multiples of 10 if($j % 10 != 0){

function recValues(){
$contents_of_page = file_get_contents('../bible1.html');
preg_match_all("#<td.*>(.+)</td#Ui", $contents_of_page, $tdInnerHTML);
$totaltds = count($tdInnerHTML[1]);
print_r($tdInnerHTML[1]);//prints all TD contents 
	$tdValues = array();
	$tdValues = "";
	for($j = 0; $j < $totaltds; $j++){
		if($j % 10 != 0){
			$tdValues .= "'".$tdInnerHTML[1][$j];
			$tdValues .= "', ";
			if($j % 10 != 0 + 9){
				$tdValues .= "'";
				$tdValues .= "<br />";
				}
			}
		}
	return $tdValues;
	}
	echo "<span style='font-weight: bold;'>".recValues()."</span><br />\n";

PHP:

So it's this part of the code that has to be fixed. I want to insert at every (multiple of 10) + 9. In other words 19, 29, 39...

			if($j % 10 != 0 + 9){
				$tdValues .= "'";
				$tdValues .= "<br />";
				}
			}
