Convert string into a 2d array by splitting on two delimiters

I need to separate a string value on @ , then explode those values by ,.

$str = '1000,10.00,10000.00@500,5.00,2500.0';


$ex = explode('@',$str);
 //result = Array ( [0] => 1000,10.00,10000.00 [1] => 500,5.00,2500.00 );
 
$ex2 = explode(',',$ex);
//result need Array ( [0] => 1000, [1] => 500, [2] => 2500);

You can use this method:

<?php
$str = '1000,10.00,10000.00@500,5.00,2500.0';
$arrayResult = [];
$arrayData = explode('@',$str);
foreach($arrayData as $sing){
    $arrayResult[] = explode(",",$sing);
}

echo "<pre>";
print_r($arrayResult);
echo "</pre>";
