如何按顺序而不是随机地创建数组输出字符串

Question

Here is the code

function salert_get_name() {
    $rand_name = $this->salert_settings['popup-names'];     
    $text_array = explode(',',$rand_name);
    $name = array_rand($text_array,1); 

    return $text_array[$name];
}    

function salert_get_country(){
    $rand_country = $this->salert_settings['popup-countries'];
    $country_array = explode(',',$rand_country);
    $country = array_rand($country_array,1);

    return $country_array[$country];
} 

That is I want the first name and first country in my array to match
