Php – Unserialize string incoming string

I have serialized array. It is serialized into string looking like:
*field1_name*|*field1_value*;*field2_name*|*field2_value*;*field3_name*|*field3_value* etc.
I need to get value of field 3.

At this moment i get it by:

explode("*|*", explode("*;*", serialized_array)[3])[1]

but i’m almost sure that there is better way to do this.
Is in php function that allows to turn it into associative array?

    If i understand Your idea step 1 should looks like:

    $query_string = str_replace(["*;*", "*|*"], ["&", "="], $serialized_string);

    All of "*", "|", ";" can be in field_value, so replace all of them isn't a good way.

    $serialized_string = "*field1_name*|*field1_value*;*field2_name*|*field2_value*;*field3_name*|*field3_value*";

// Step 1: Convert the serialized string into a query string format
$query_string = str_replace(["*", "|", ";"], ["&", "=", ""], $serialized_string);

// Step 2: Use parse_str() to convert the query string into an associative array
parse_str($query_string, $result);

// Step 3: Access the desired field by its name (e.g., field3_name)
$field3_value = $result['field3_name'];

// Print the value of field3_name
echo $field3_value;

    This approach is more flexible than using multiple explode() calls and will work for an arbitrary number of fields in your serialized string.

    Very-very-very basic solution:

    function unserializer ($serializedData)
{
    $unserializedData = [];
    
    foreach (explode('*;*', trim ($serializedData, '*')) as $keyVal) {
       [$key, $val] = explode ('*|*', $keyVal);
       $unserializedData[$key] = $val;
    }
    
    return $unserializedData;
}

$ser = '*field1_name*|*field1_value*;*field2_name*|*field2_value*;*field3_name*|*field3_value*';
var_export (unserializer ($ser));

    In the real world, errors may need to be handled
