number_format() and an array

[ztron]

I am trying to use number_format to format the data in an array, but I was unsuccessful with my attempts. This is the code I've been using, but I want to use number_format() since it is a currency field.

             print("<tr><td>" . $row[0] . "</td>");
             print("<td>" . $row[1] . " " . $row[2] . "</td>");
             print("<td>" . $row[3] . "</td>");
			 print("<td>" . $row[4] . "</td>");
			 print("<td>$" . $row[5] . "</td></tr>");

I was given a suggestion like this:

print '$'.number_format(123.4,2);

How would I be able to format the array like that? I was trying something like this, but it wasn't working:

print("<td>" '$'.number_format($row[5]) "</td></tr>");

Any help or suggestions are appreciated.

the ,2 in the number_format function specifies the amount of digits to display after a decimal. Without it, it with format the number to a whole, so you would need

print("<td>$".number_format($row[5],2)."</td></tr>");
