[RESOLVED] calling a function within printf()

[revez2002]

Hello,

I am using the printf function to display the rows from my query. Everything works fine, but I want to add a custom function that will format the $extended_price variable so that this number is displayed with commas for numbers in the thousands. The custom function that I created is called NumberWithCommas, and I want to call it within the prinf function. I tried doing it by adding ".NumberWithCommas($extended_price)." in place of $extended_price, but this did not give me the result I was looking for.

Is it possible to call another function within printf, or will I have to somehow modify that variable outside of that function?

<?php
// Display each record returned by the query as a row
printf("
<tr>
<td width=\"10\"></td>
<td class=\"general_content_02_orange\" height=\"25\" width=\"280\" align=\"left\" valign=\"middle\"><input type=\"hidden\" name=\"%s\" value=\"%s\">%s</td>
<td width=\"110\" align=\"right\" valign=\"middle\"><input class=\"lite_green_02\" type=\"text\" name=\"%s\" value=\"%s\" style=\"width:70px;\"></td>
<td width=\"110\" align=\"right\" valign=\"middle\"><input class=\"lite_green_02\" type=\"text\" name=\"%s\" value=\"%s\" style=\"width:70px;\"></b></td>
<td class=\"general_content_02\" width=\"100\" align=\"right\" valign=\"middle\">$extended_price</td>
<td width=\"40\" align=\"right\" valign=\"middle\"><img border=\"0\" height=\"16\" width=\"17\" align=\"absmiddle\" src=\"content/projects/images/remove_checklist_item_button.jpg\">&nbsp;</td>
</tr>\n",

$psq_ID_str, $row_psq["psq_ID"], 
$row_psq["item_name"], 
$units_quoted_str, $row_psq["units_quoted"],
$price_quoted_str, $row_psq["price_quoted"]);
?>

If I understand what you are asking...

... here is an absurdly simple example:

<?php
// define a real simple function
function varyGame() {
	$games = array('PHP', 'XML' , 'XHMTL', 'JavaScript', 'CSS');
	$num = rand(0, count($games) - 1);
	return $games[$num];
}


printf("Name: %s<br />Game: %s", 'Boscoe', varyGame());
?> 

Hope that helps...

Thanks for the suggestion. However, I was unable to get the results that I needed using a single printf(). It occured to me that I might try breaking the information up so that I could deal with the $extended_price variable on its own. This approach worked, and I have copied the code below for a reference to others that might have the same issue.
