expected results (how able echo them out in php)

section 1

• question 1
• question 4
• question 7

section 2

• question 2
• question 9

section 3

• question 3

you should use loop.

foreach($section $k=>$section) {    echo "section $k";    foreach($section $i=>$question)    {      echo "question $i ".$question['assessment_id']; //more fields available here    } }
