如何使用php将逗号替换为不同的字符串数组值？

Question

Getting hard time to fix this one, please help me :(

$string = "Question 1 , Question 2, Question 3"; // Value came from Database;

My code is

while($row = mysqli_fetch_assoc($result)) 
{ $alphas = range('A', 'C');
            $output = str_replace(',', ('<br/>'.$alphas[$row]), $string);
            echo $output
} 

The Result will be like this:

Question 1

Question 2

Question 3

What I want is , every comma will change into different value

A. Question 1

B. Question 2

C. Question 3

Please help me guys! thank you

Answer 1

$string = "Question 1 , Question 2, Question 3";

$arr=explode(',',$string);
$alphas = range('A', 'C');

$final=array();


for ($i=0;$i<count($arr);$i++) {

$final[]=$alphas[$i].'. '.trim($arr[$i]).'<br>';

}

echo(join($final));
