RE: [PHP-GENERAL] Array_walk

I am going to assume that you are calling array_walk within a loop of some kind as it is not in your code below. If that is the case, then when you call array_walk within your loop, you could have something like the following: <code> $grandtotal = 0 ; while loop { ... ... $grandtotal = your function where you are calculating the cost ; } echo $grandtotal ; </code> Sam Masiello System Analyst Chek.Com (716) 853-1362 x289 smasiello@chekinc.com -----Original Message----- From: Phil Ahern [mailto:phil@caint.com] Sent: Monday, June 26, 2000 3:34 PM To: PHP Subject: [PHP-GENERAL] Array_walk Hey All I have an array of id numbers on which I use the array_walk to search a database of the for the relevant price and description of the id. What I want to do is return the total price for all the id numbers in the array. Anyone know how to do that or maybe a better way. The code is below.. function bookarraycheck($item) { global $conn_id; $result = ifx_query("select title, price from books where bookid = '$item'",$conn_id); $r = ifx_fetch_row($result); ifx_free_result ($result); echo "<TR><TD WIDTH=\"50%\" VALIGN=\"TOP\">".$r["title"]."</TD>"; echo "<TD WIDTH=\"50%\" VALIGN=\"TOP\">£ ".$r["price"]."</TD></TR>"; $totalcosts += $r["price"]; return $totalcosts; } array_walk( $book, 'bookarraycheck' ); Thanks Phil Caint.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
