Completely Delete A Specific Array Index
I was wondering if anyone could tell me if there is a way to completely delete a specific array index once it has been set. For instance, I have an array with 50 indexes (0 - 49) sizeof = 50. Now, I want to eliminate 10 indexes, making my array sizeof 40 and having array indexes 0-39.

Listing Table Data With An Option To Delete Each Individual Item.
Was wondering if anyone could help me with a PHP, MySQL problem. I am completely new to PHP and MySQL.

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

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 } } }}

Index Of Array
I uses the function in_array to find out if a specified word appears in a specified array, if it is there I want to get the index of this word in the array. So I can use this index to set a value in array2, at the same index. Jeg bruker in_array for å sjekke om et bestemt ord finnes i en bestemt array, hvis det finnes vil jeg få hentet ut indeksen dette ordet har i array'en. Så vil jeg legge inn et tall i en annen array på samme index som ordet. if (in_array($word, $array1)) { $i = index_of_word($array); $array2[$i] = $number_to_put_in_same_index_as_the_word_in_array1; }

Sort Array Without Index
I'd like to sort a multidimensional array that hasn't numerical index, in fact it is like: Array ( [mobile] => Array ( [name_str] => mobile [relationCount_int] => 1 ) [video] => Array ( [name_str] => video [relationCount_int] => 2 ) [flash] => Array ( [name_str] => flash [relationCount_int] => 1 ) [tool] => Array ( [name_str] => tool [relationCount_int] => 1 ) ) And I'd like to sort, for instance for the value of "relationCount_int", so the new order should be something like: Array ( [video] => Array ( [name_str] => video [relationCount_int] => 2 ) [mobile] => Array ( [name_str] => mobile [relationCount_int] => 1 ) [flash] => Array ( [name_str] => flash [relationCount_int] => 1 ) [tool] => Array ( [name_str] => tool [relationCount_int] => 1 ) )

Array Index Question
I have source information in a file, and (part of) this information comes as coordinates. A coordinate consists of a letter followed by a number, ranging from a1 to i9 I'd like to count the number of occurrences of each coordinate, and put them in a matrix. The matrix should look like this (metasyntax): matrix = array ['a'..'i'][1..9] Later on in the script I'd like to be able to refer to a cell in the matrix by using the same letter/number combo. I know I can define an array using strings as keys, but how can I define a..i as keys without the need to specify them all individually?

Quotes Around Array Index?
I have a question about quoting array indices. This is from Rasmus Lerdorf's Programming PHP: Quote: You don't have to quote single-word strings. For instance, $age['Fred'] is the same as $age[Fred]. However, it's considered good PHP style to always use quotes, because quoteless keys are indistinguishable from constants. When you use a constant as an unquoted index, PHP uses the value of the constant as the index: Code:

Back Referencing To Get An Array Index?
My website needs to allow users to specify where a thumbnail image will appear in the text ($articleText) they submit. The thumbnail filenames are held in a single-dimensional array called $photos e.g. the users are to type [thumb4] to specify they want thumbnail four ( from array position 4 ) I was hoping the following expression would work, but it doesn't. The returned text always includes <img src="thumbs/"> i.e. no image filename is inserted. (I was expecting something like <img src="thumbs/dave.jpg"> ) $articleText = preg_replace("/[thumb(d+)]/", "<img src="thumbs/".$photos[$1]."">", $articleText);

Accessing Numerical Array Index In Foreach
I have no trouble looping through an array using foreach. To keep track of the index, I set a variable before the loop and increment it in the loop: $index = 0; foreach ($array as $item) { blah; $index++; do something that requires knowing the index of the current item; } Is there a better way to access that index value?

Getting A (non-radio) Button's Index Number From Array
If you could assist me with the following situation, I have a table of data retrieved from database displayed on screen. To each row of data, I have added action buttons, such as "Edit", "Add", and "Comment". Since I do not know how many rows of data will be retrieved - and therefore how many buttons I need - I am using button arrays for each button, like so: echo "<input type="submit" value="Comment" name="Comment[]" />"; In the php file that processes the input from this form, I have the following code, which I was under the impression would give me the index in the Comment array of the button that was fired. if (isset($_POST['CommentMedicalHistory'])) { $indexOfComment = each($_POST['CommentMedicalHistory']); echo "index = {$indexOfComment['key']}"; } Unfortunately, it is returning 0 as the index all the time, even when I do not click on the Comment button in the first row. Do you know by any chance how I could get the correct index of the button that was pressed from the array?
