Exploding a String into an Associative Array without Iterative Loops

Exploding a string into an associative array without using loops can be achieved through a combination of array functions in PHP 5.5 .

Solution:

To accomplish this, we utilize the following steps:

1. Split the string into chunks of two elements each, alternating between key-value pairs:

   <code class="php">$chunks = array_chunk(preg_split('/[-,]/', $input), 2);</code>

2. Extract the keys and values separately using array_column:

   <code class="php">$keys = array_column($chunks, 0);
   $values = array_column($chunks, 1);</code>

3. Combine the keys and values into an associative array:

   <code class="php">$result = array_combine($keys, $values);</code>

Example:

Given the input string '1-350,9-390.99', the output would be:

<code class="php">Array
(
    [1] => 350
    [9] => 390.99
)</code>
