Parse string with two sets of delimiters to form an associative array

Question

Input:

$this->request->get(['opt']) = '337:230,323:112';

My Current Code:

$option = explode(",", $this->request->get['opt']);

foreach ($option as $key => $value) {
    echo $value . "<br>";       
}

My Results:

337:230
323:112

Question: How can I separate the above data into an associative array?

Desired Result:

[
    337 => 230, 
    323 => 112,
]

Answer 1

It looks like you just need to explode again on the colons, so perhaps something like this?

<?php

$opt = '337:230,323:112';

$option = explode(",", $opt);

foreach ($option as $pair) {
    list(key, $value) = explode(':', $pair);
    $array[$key] = $value;
}

print_r($array);

Array
(
    [337] => 230
    [323] => 112
)
