How the PHP two-layer foreach loop sets the initial value for the inner loop variable =0

$question):?>
$answer):?>

I don't understand what you mean, for example. or explain how you want to output it.

The requirement is such a problem the following several options questions are a one-to-many relationship with options I wrote two foreach loop data to read,
For example, question 1 The following option is 1. Option a 2. Option B question 2 The following option is 1. Option C 2. Option d The title of the option here I want to do with $i, but two foreach after question 2 is the number of the option that starts with 3

 $question):?>
 
 
            
  
  
 
  
  
 
    .

  '; $questions = array (    ' problem 1 ', ' question    2 ',    ' question 3 '); $answers = Array (    ' option A ', ' option B '),    array (' option C ', ' Option d '),    array (' option e ', ' option F '), foreach ($questions as $k = + $question) {    echo ' Q '. $k + 1). '
';    foreach ($answers [$k] as $i = = $answer) {        echo ' option '. $i + 1). ' '. $answer. '
';    }    Echo '
';}? >

Q1
Option1 Option A
Option2 Option B

Q2
Option1 option C
Option2 option D

Q3
Option1 option E
Option2 option F

#3 Code
The 8th line should read
The 14th line should read

The inner layer iterates through the $answers array each time, and takes only a small amount of data
It's not worth the candle, it is recommended to adjust the data organization method (see # #)

Of course, you can cluster the $answers before the main loop starts.
