将动态数组与动态键组合到单个数组中

Question

I have this dynamic multiple arrays that I need to combine in one array and serialized them. The problem is I need to keep both key and value.

$arr = array($bet_option_id => $bet_option_name);

Here i need to keep both bet_option_id AND bet_option_name. Then this result output:

Array ( [997650802] => Over 2.5 ) 
Array ( [997650807] => Yes )

This need to be simply

Array
(
  [997650802] => Over 2.5
  [997650807] => Yes
)

As it's dynamic, sometimes not comes with just single array so apparently I couldn't get it working. I need to retrieve both bet_option_id & bet_option_name. Tried something like this:

 $arr = array($bet_option_id => $bet_option_name); //This is where all array keys, values are stores
 $result = array();
 foreach ($arr as $array) {
     $result = array_merge($result, $array);
  } 

Any inputs will be nice.

Answer 1

Rather than create individual arrays like...

$arr = array($bet_option_id => $bet_option_name);

If you first create an empty array ( like you do with $result)

$arr = array();

and then add each item in using

$arr[$bet_option_id] = $bet_option_name;

Then you don't need to manipulate the array after - just create it as you want it in the first place.
