Array Explode Problem Result In A 6 Item Array
I have the following: $BB_Basket = "basket=¦APL6007,2.00¦AVX8900,1.00¦ARCAV500,1.00"; $basket_containers = explode('¦', $BB_Basket); unset($basket_containers[0]); print_r($basket_containers); This results in Array ( [1] => APL6007,2.00 [2] => AVX8900,1.00 [3] => ARCAV500,1.00 ) Now when I try to explode further with $basket_items = explode(',', $basket_containers); print_r($basket_items); This results in Array ( [0] => Array ) This should result in a 6 item array. Any ideas what I'm doing wrong?

Item In Array
I have an array, set up like this: $this->navigation_array['Home'] = array('text' => 'Home', 'act' => 'Home', 'redirect' => 'No', 'active' => 'Home', 'link' => 'index.php?act=home', 'default' => 'Info'); $this->navigation_array['Forums'] = array('text' => 'Forums', 'act' => 'Forums', 'redirect' => 'No', 'active' => 'Forums', 'link' => 'index.php?act=forums', 'default' => 'Info'); $this->navigation_array['Users'] = array('text' => 'Users', 'act' => 'Users', 'redirect' => 'No', 'active' => 'Users', 'link' => 'index.php?act=users'); $this->navigation_array['Config'] = array('text' => 'Configuration', 'act' => 'Config', 'redirect' => 'No', 'active' => 'Config', 'link' => 'index.php?act=config'); I want to find the first item inserted into the array, namely "Home". What is the fastest way to just call the first entry? You cant use $this->navigation_array[0] in this case because the keys are text not numbers.

Modify Array Item
I'm building a shopping cart and need to add the function so if an item is selected twice, the 'quantity' counter increments. I can't get the syntax right for modifying the array value. I have this: foreach ($_SESSION['basket'] as $key => $row) { if ( $row['gnsz']==$gnsz) { $newqty=$row['qty'] ; $newqty++; $row['qty']= $newqty; } } it picks up the first qty value but I can't seem to modify it in the array. I'm making a dumb mistake somewhere .

Put The Itemid Of An Item Into An Array.
$count = 1; foreach($trade as $val) { $val = checkinput($val); $sel=mysql_query("SELECT * FROM `inventory` WHERE `ID` = '$val' AND `userid` = '$userid2'") or die(mysql_error()); $n=mysql_num_rows($sel); if($n == 0) { $input = "You do not own this item."; error($input); } $g=mysql_fetch_array($sel); $itemid = $g['itemid']; $itemid[$count] = $itemid; $count++; } Basically, my script is trying to put the itemid of an item into an array. The problem i'm getting is that, it's not saving the values in the array. For example, if i have 3 items and it puts them into the array, it will only save the 3rd item in the array $itemid[3] and 1 and 2 will be blank.

Item In A Multidimensional Array
I have a multidimensional array (I think). It is an array that has arrays inside it. The inside arrays all have the same structure, (qty, product, color, size). How do I count how many items are 'White' * qty? I looked into the php manual and found array_count_values but others say it doesn't work with MD arrays.:confused: array( [0] array([0]qty, [1]product, [2] color, [3] size) [1] array([0]qty, [1]product, [2] color, [3] size) [2] array([0]qty, [1]product, [2] color, [3] size) [3] array([0]qty, [1]product, [2] color, [3] size) [4] array([0]qty, [1]product, [2] color, [3] size) [5] array([0]qty, [1]product, [2] color, [3] size) [6] array([0]qty, [1]product, [2] color, [3] size) ...)

Extra Item In My Array
Why is my code. $urlarray = explode("/", "/about/new/index.php"); print_r($urlarray); returning this Array ( [0] => [1] => about [2] => new [3] => index.php ). Perhaps I am being dense but why do I have an extra empty value at the beginning of the array. Is there any way I can make it return the ones I want (ie only those containing an actual value) or do I simply have to work around this.

Shopping Cart Item Array
Trying to build a small simple shopping cart and I am having difficulty getting the solution. The cart is displaying each product, but it is overwriting the values. So if I have added 10 products, it shows ten items, but each item has the values of the last product I added. I think that this may be due to me trying to use a key to store both an array and string at once, but Iam not sure. I have looked at other examples but due to different methods, syntax is throwing me off. Code:

Arrays : Returning A Reference To An Array Item ??
I am currently storing a set of objects inside an array, $itemlist = array(); $itemlist[] = new item("myitem"); //... and I am looking to develop a search function, which returns a reference to the found item. function &search_item($itemlist,"myitem") { //... } I am trying to figure out how to obtain a reference to a given item in an array. Indeed, foreach() and each() seem to work on copies of the data in the array. For example: $array = array("a","b","c","d"); print_r($array); foreach($array as $v) $v="xxx"; print_r($array); // $array is unchanged reset($array) ; while(list(,$v)=each($array)) $v="xxx"; print_r($array); // $array is unchanged, again

Iterator First Item?

Pseudocode: foreach($data as $row) { if first time through iteration do something with $row else do something which each remaining $row } Is this possible? I think I could use a regular 'for' loop, using the length of the $data array as a guide, and then an 'if..else' structure to see if it is the first time through the 'for' loop, but I was looking for a more elegant solution.

How To Make Url Links To An Item
Hi i was wondering if anybody could tell me how to make url links to an item in my site from a list of search results.

Event Name: "."</b>".$row["Name"]."<br>"); echo("<b>"." Event Type: "."</b>".$row["Eventtype"]."<br>"); echo("<b>"." Venue Name: "."</b>".$row["VenueName"]."<br>"); echo("<b>"." Event Start: "."</b>".$row["EventStart"]."<br>"); echo("<b>"." Event End: "."</b>".$row["EventEnd"]."<br>"); echo("<b>"." Availability: "."</b>".$row["Availability"]."<br>"); echo("<b>"." Description: "."</b>".$row["Description"]."<br><hr>"); } } ?> For example if i enter an event type as 'comedy', a list of search results will come up from the form input displaying comedy events. Now from these results i would like to be able to click on Venue Name and this would link to that page in another part of my site. I hope this explanation is o.k, if not post a thread & i'll try and explain a bit better. Thanks for any help
