Write A Conditional Statement To See If The Current Item In An Array Is The Last Item.
This seems like it would be so simple, but I haven't been able to solve it. I want to write a conditional statement to see if the current item in an array is the last item. I tried

if (count($array) == (current($array))

but that didn't work. count($array) will give me the number of items in the array. What do I use for the current position in the array.

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. I have been trying to find a way to
list data from a table on a web page and after each individual item
have a hyperlink to allow users to delete the information listed. Can
anyone help?

i.e.
Name Age Sex
------------------------------------------
Adam 21 M delete
Betty 22 F delete
Chris 23 M delete
Daisy 24 F delete

------------------------------------------------------------------------------------------------------------------------------
(delete after 'Sex' would be the hyperlink to delete that entire line
(row) from the table).

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.

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.

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.

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:

Extra Item In My Array

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.

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');

$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 ) {
