Deleting An Array Item
I have a standard array:
$foo = array(
0 => 'abc'
1 => 'def'
2 => 'ghi');
and I have a variable, $bar, which equals 'def' ... and I want to check
my array to see if the value of $bar exists in the array, and if it
does, delete it from the array.
if (in_array($bar, $foo)) {
// what goes here???
}
I've done this before, but for the life of me, I'm drawing a blank now.
Help a bruthah out?

Deleting A Single Item From The Middle Of An Array?
I have an array that contain objects, I want to be able to test against the id of that object and remove it from the array. In it's simplest for I want to go from this: $people = array('Tom', 'Dick', 'Harriet', 'Brenda', 'Jo'); ...to this... $people = array('Tom', 'Dick', 'Brenda', 'Jo'); The fact that the items in the array are objects should not matter right? Plus I've already written my loops and conditionals to check which item i need to remove. function removeItem ( $item ) { $len = count ( $_SESSION['basket_arr'] ) ; if ( $len == 1 ) { emptyBasket ( ) ; } else { for ( $i = 0 ; $i < $len ; $i++ ) { if ( $item->id == $_SESSION['basket_arr'][$i]->id ) { //$_SESSION['basket_arr'][$i] must go } } }}

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.

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

Problems Deleting Array Element
I have a string of product IDs in a comma seperated list. I wish to remove one instance of a specified digit from the list. The passed value ID is used to determine which ID to remove. To achieve this I have used the explode function to split the string into an array. I then want to remove one instance of the specified ID using the unset method. Finally I want to reconstruct the list using the implode function. This seems simple enough in theory although I am having problems getting it to work. Code:

Checking If A Value Is Not In An Array And Deleting Record From Database
I have been trying to figure this one out and have come up against a brick wall although I know it should be relatively simple. I have a form that passes an array to a php script from a multiple select box that is created dynamically. If a user deselects an item then I want to delete the record from the database but am having a big problem with it. The table in the dbase is quite simple with just three fields: id classid formid Basically, the form send through a classid and a formid value and I want to delete any records that have a classid that are not in the form array and have a formid which is passed as a hidden value. I suppose really what I want is to know how to see if a classid is not in the array that is passed.

Basically when the user presses the submit button I would like all rows in the database table "users" with the corresponding column "date" to be deleted when the form variables date correspond to those in the "date" rows.

Batch File Deleting And Folder Deleting
I have a folder in my web site where I used php to create and copy in files. but now I can't delete them easily. The only way I know how that is possible is through php. I get an error the following ftp error: 550 th: Permission denied I had the chmod() set to 0777 on every file and folder. But I still seem to loss control over the files when I try and do things with them through other means. I think it is because the user I use to access the files via ftp a diffrent user. So I tryed to add a function with chown() for the new files I was posting and uploading. It didn't work on those new files. so it looks like the only thing I can do is use the unlink() function which deletes the files fine. The only problem is now I have something like 100 sub directories all with files in them. I need to figure out a way to batch delete them. I can't find a script that goes through and finds all file contents including all sub directories and unlink those things. I found some that will use a for loop to list out the contents of a folder but it is just files. No sub directories. Any body got any ideas on which functions I should use or know where a script is that I can base mine off of. I am not sure how to approach this since what I tryed with chown and chmod has failed thus far. I currently have no code and am starting from scratch on this batch flushing of my directory.

Iterator First Item?
Let's say I have the code: foreach($data as $row) { do something with each $row } Is there a way to do something specific to the first item iterated? Pseudocode: foreach($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.
