如何将数组中的值提取到变量中?

I'm using the following code to print my array:

//SQL Query
$query = "SELECT wp_arf_entry_values.entry_value, wp_arf_entry_values.id FROM wp_arf_entry_values WHERE entry_id=1";

//Execute the SQL query and return records
$result = mysql_query($query);

while($row = mysql_fetch_assoc($result)){
     $results[] = $row;
}

//Print array in human readable form
print("<pre>".print_r($results,true)."</pre>");

This is the output:

Array
(
    [0] => Array
        (
            [entry_value] => John
            [id] => 1
        )

    [1] => Array
        (
            [entry_value] => Doe
            [id] => 2
        )

    [2] => Array
        (
            [entry_value] => 19
            [id] => 3
        )

    [3] => Array
        (
            [entry_value] => Male
            [id] => 4
        )
)

I'm having a hard time to figure out how I can extract the array's values into variables, like this (not actual code, just an example):

$fName = 'entry_value' that has ID = 1
$lName = 'entry_value' that has ID = 2
$age = 'entry_value' that has ID = 3
$genre = 'entry_value' that has ID = 4

I've researched here for the past hour but I can't find an answer that helps me. What's a feasible way to do this?

    Assumption:id values are unique in your db

    change your code to

    $results = array();
    while($row = mysql_fetch_assoc($result)){
         $results[$row['id']] = $row['entry_value'];
    }
    
    //Print array in human readable form
    print("<pre>".print_r($results,true)."</pre>");
    

    And you can have your values as:

    $fName = $results['1']
    $lName = $results['2']
    $age   = $results['3']
    $genre = $results['4']
