How can PHP beginners effectively use explode and array_combine to create an associative array from a string array?

To create an associative array from a string array using explode and array_combine in PHP, first, you need to split the string array into keys and values using explode. Then, you can use array_combine to combine these keys and values into an associative array.

$string = "key1:value1,key2:value2,key3:value3";
$stringArray = explode(",", $string);

$keyValueArray = [];
foreach ($stringArray as $item) {
    list($key, $value) = explode(":", $item);
    $keyValueArray[$key] = $value;
}

print_r($keyValueArray);
