remove item from array

[Anon]

i'm using this function to remove a variable called tool from an array called $basket

unset($basket['tool']);

but it doesn't seem to have any effect on the array.
ou and one more thing if there happens to be dublicate entries of the same variable, how can i only remove one and leave the rest alone?

the unset() function will remove the array index where the key is 'tool', not the value of 'tool'. If you know the key then you can use unset, if not you can use a foreach loop:

$array = array (
'first' => 'Joe',
'last' => 'Smith',
'favorite_band' => 'tool',
'age' => '24'
);

unset ($array['favorite_band']);

or

foreach ($array as $key => $value) {
if ($value == 'tool') {unset ($array[$key]);}
}

but if there would be dublicate values in the array,

how can I remove only one variable with the specified value?

I made something like this: but it isn't enough automatic as i would want it to be.

first i count the variables that have the specified value, in this case "tool"

$count = array_search("tool",$basket);
foreach ($basket as $key => $value) {
if ($value == 'tool') {unset ($basket[$key]);}
}
and now i would add variables into the array, so that in the end it would seem that just one variable was removed
if($hulk = 2) {
array_push($korv,"tool"); }
