PHP: Accessing child arrays when you don't know the parent's keys and you can't just search for the value needed -

i have php array containing film descriptions ($descriptions) , php array containing showtimes , ticket quantities ($stock) movies. each unique film id in $descripctions, need of showtimes , tickets $stock.

is there no built-in php function search unique id , homecoming chain of keys needed access value? can't find elegant solution after total day of googling , reviewing every array function in php manual twice.

if there's no more elegant solution, best approach custom recursive function? if so, guidance on best approach / command structure? maybe counting array elements , using several levels of while loops go through each level of array?

here's origin of $stock array i'm trying info -- won't post entire print_r() because source array on 67,000 lines long much should indicate construction i'm working with.

thank much!!!

array ( [products] => array ( [venue] => array ( [0] => array ( [title] => 3-d digital cinema [length] => 25 [memberonly] => 0 [shows] => array ( [show] => array ( [0] => array ( [title] => planet [location] => 3-d digital cinema [eventnumber] => 521 [date] => array ( [0] => array ( [eventdate] => 2012/01/01 [times] => array ( [time] => array ( [0] => array ( [starttime] => 13:00:00 [instock] => 110 ) [1] => array ( [starttime] => 16:00:00 [instock] => 110 ) ) ) ) [1] => array ( [eventdate] => 2012/01/02 [times] => array ( [time] => array ( [0] => array ( [starttime] => 13:00:00 [instock] => 110 ) [1] => array ( [starttime] => 16:00:00 [instock] => 110 ) ) ) )

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
