Searching through exploded string based on variable combined with string

In my database I have a string called "Cart".

$cart = "1+10,2+10,3+10,5+10,6+10"
$openCart = explode(",", $cart);


Inside $openCart I want to search for the number and plus signs before adding new information to this array.
I have tried array_search and in_array but neither let me search for a value like "3+".
array_search only allowed me to search for complete strings, such as "3+10" while in_array didnt like it when I ended my search string on the plus sign.

Further context:
In the end, the ideal code for this function would be somewhere along the following:

$pID = 3;
$pOrder = 4;
$openCart = explode(',', $cart);

//Search where $pID . "+" matches a value inside $openCart
$specProd = explode ('+' $openCart[/*Location that got matched*/]);
$specProd[1] = $specProd[1] + $pOrder;

$impProd = implode ('+', $specProd);
$specProd = impProd;
$newCart = implode (',', $specProd);

//upload the string of $newCart back to the database.


Currently I am just stuck on searching through the array and any help would be appreciated.

preg_grep

array_map

You can use preg_match.

To find integer followed by '+':

$string = '423+10';
if(preg_match('/d++/',$string))
echo 'match found';


For dynamic integer:

$string = '6+10';
$d = 6;
preg_match('/'.$d.'++/',$string);
echo 'match found';


It finds an element's key

<?php
$cart = "1+10,2+10,3+10,5+10,6+10";
$openCart = explode(",", $cart);
$needle = "3+";
$return = array_keys(array_filter($openCart, function($var) use ($needle)
return strpos($var, $needle) !== false;
));
if(!empty($return))
// do something
