How to remove specific number of elements from array - php

Question

I have a function, which delete elements from array:
function remove_from_cart($prod_name,$price,$params,$count)
{
$cart = array(
"0" => array (
'name' => 'Bolognese - Small (26cm)',
'params' => '',
'price' => '12'),
"1" => array (
'name' => 'Bolognese - Small (26cm)',
'params' => '',
'price' => '12')
);
$prod_arr = array(
"name"=> $prod_name,
"params"=> $params,
"price" => $price);
$count = count( array_keys( $cart, $prod_arr ));
while(($key = array_search($prod_arr, $cart)) !== false) {unset($cart[$key]);}
return array('cart' => $cart, 'count' => $count);
}
$rem = remove_from_cart('Bolognese - Small (26cm)', '12', $params, 1);
//here is i want to remove just 1 of 2 elements
How to modify this function to have ability to set number of elements which i want to delete from array?
Thank you!

Your example and question is not quite clear, but you can check this solution:
<?php
function remove_from_cart($prod_name,$price,$params,$count)
{
$cart = array(
"0" => array (
'name' => 'Bolognese - Small (26cm)',
'params' => '',
'price' => '12'),
"1" => array (
'name' => 'Bolognese - Small (26cm)',
'params' => '',
'price' => '12'),
"2" => array (
'name' => 'Bolognese - Small (26cm)',
'params' => '',
'price' => '12')
);
$prod_arr = array(
"name"=> $prod_name,
"params"=> $params,
"price" => $price);
$i = 0;
while(($key = array_search($prod_arr, $cart)) !== false && $i < $count) {unset($cart[$key]); $i++;}
return array('cart' => $cart, 'count' => $count);
}
$params = '';
$rem = remove_from_cart('Bolognese - Small (26cm)', '12', $params, 1);
var_dump($rem);
This would return two elements, because they are 3 elements and you pass 1 for $count if you pass 2, it would return 1 element:
Result for $rem = remove_from_cart('Bolognese - Small (26cm)', '12', $params, 1); :
array(2) { ["cart"]=> array(2) { [1]=> array(3) { ["name"]=> string(24) "Bolognese - Small (26cm)" ["params"]=> string(0) "" ["price"]=> string(2) "12" } [2]=> array(3) { ["name"]=> string(24) "Bolognese - Small (26cm)" ["params"]=> string(0) "" ["price"]=> string(2) "12" } } ["count"]=> int(1) }
Result for $rem = remove_from_cart('Bolognese - Small (26cm)', '12', $params, 2); :
array(2) { ["cart"]=> array(1) { [2]=> array(3) { ["name"]=> string(24) "Bolognese - Small (26cm)" ["params"]=> string(0) "" ["price"]=> string(2) "12" } } ["count"]=> int(2) }
