array_walk loses data

code green
1,726 Recognized Expert Top Contributor
Using the third parameter to pass the address of a user array to array_walk fills the user array with data.
But once array_walk finishes executing the user array empties. Can any body explain this?
[PHP]$assocPriceList s = array();
//Create price lists lookup table
if(array_walk($ priceLists, 'createAssoc', $assocPriceList s))
{
print_r($assocP riceLists);
//Prints Array(). assocPriceLists is empty

function createAssoc($va lues,$dummy,&$a ssocPriceLists)
{
$assocPriceList s[$values['price_list_id']] = $values['price_list_nam e'];
print_r($assocP riceLists);
//Can see assocPriceLists fill up here
}[/PHP]

Folks, I have a multi-dimensional array that I read from my mysql database. I'd like to run strip slashes against each element and I'm pretty sure that array_walk() (or array_map) is likely to solve my problem - But I've not got the foggiest on how to use it - I've taken a look in the php.chm manual supplied from php.net and I don't seem to have had any success so far - Can anyone suggest how I could stripslashes to every element...

Hi, I have never used array_walk, and quite frankly, cannot see why I should use it instead of foreach. Can someone shed some light on the cases where array_walk is the one to use, and what php developers where thinking when they coded this operator. Thanks. --

I have another post regarding this "attendance" report of mine...this one concerns one of my sub-reports. It loses its alphabetical sorting when inserted in the master report. When run separately, it's perfect. Once inserted and printed in the master report...the data is in a random order. Any suggestions?

A little background: We have an Access 2002 based user interface to our SQL Server 2000 database. The interface is a tabbed form with two of the tabs containing a subform. Data is pulled from the SQL Server using several stored procedures, one sproc for the main form and an additional sproc for each subform. All data is pulled from the SQL Server using ADO; the resulting client side (disconnected) ADODB.Recordset is then applied to each...

Page 1 will is loaded when the page that contains the ascx (parent of the treeview) is loaded. This is all cool. The treeview displays correctly. When I click the ...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
