添加到键值配对数组

Question

I have 2 arrays. One is initialized with key names but with empty values :

$hits_arr = array(
    'HD'=>'',
    'CT'=>'',
    'PS'=>'',
    'LS'=>'',
    );

Consider I have such string which is split into 4 different array elements:

$val = "8/2/9/4/";
$val = explode("/",$val); 

My goal is to add each $val values to $hits_array so it would look like :

array ( 
'HD'=>"8" 
'CT'=>"2" 
'PS'=>"9" 
'LS'=>"4"
)

Answer 1

Try this:

 $counter = 0;
 foreach($hits_arr AS $key => $value)
 {
    $hits_arr[$key] = $val[$counter];
    ++$counter;
 }
