获取数组的值

Question

I am making a form in which when i submit the form i want to get the values from a array . When i var_dump the array i get the following result

array(1) { [0]=> array(3) { ["s2member_level1"]=> string(3) "400" ["s2member_level2"]=> string(3) "400" ["administrator"]=> string(3) "500" } }

i want the values s2members_level1 , s2members_level2 , administrator and their values which are 440 , 400 , 500 using a for loop so that i can update these values to their records .

Answer 1

Your data is 'hidden' in nested array. You can access it with $yourData[0]. To modify values, you can loop over the values and use reference:

foreach ($data[0] as $key => &$value) {
  $value = $value * 2;
}

In $key variable you will get s2member_level1, s2member_level2 and administrator.
