数组合PHP中的问题

Question

HI,

I got two array.

var_dump($tbDateArr);
var_dump($tbTitleArr);

output:

array
  0 => 
    object(stdClass)[16]
      public 'eventDate' => string '5' (length=1)
  1 => 
    object(stdClass)[17]
      public 'eventDate' => string '16' (length=2)
array
  0 => 
    object(stdClass)[18]
      public 'eventTitle' => string 'mar' (length=10)
  1 => 
    object(stdClass)[19]
      public 'eventTitle' => string 'tri' (length=10)

BTW,I print them as this,

print_r($tbDateArr);
echo '<br>';
print_r($tbTitleArr);
Array ( [0] => stdClass Object ( [eventDate] => 5 ) [1] => stdClass Object ( [eventDate] => 16 ) ) 
Array ( [0] => stdClass Object ( [eventTitle] => mar ) [1] => stdClass Object ( [eventTitle] => tri ) )

I tried to combin them,

$dataArr = array_combine($tbDateArr, $tbTitleArr);

I JUST WANT THE SIMPLY RESULT as this,

Array
(
    [5]  => mar
    [16]    => tri

)

Is there anything wrong? Appreciated for your help.

[updated with array_merge]

array
  0 => 
    object(stdClass)[16]
      public 'eventDate' => string '5' (length=1)
  1 => 
    object(stdClass)[17]
      public 'eventDate' => string '16' (length=2)
  2 => 
    object(stdClass)[18]
      public 'eventTitle' => string 'fuzhou mar' (length=10)
  3 => 
    object(stdClass)[19]
      public 'eventTitle' => string 'weihai tri' (length=10)

Answer 1

Assuming that $tbDateArr and $tbTitleArr entries only have a single property (eventDate and eventTitle respectively), you can do this:

$array = array_combine(
    array_map('current', $tbDateArr),
    array_map('current', $tbTitleArr)
);

If they have (or can have) more than a single property, you're better off using a good old foreach, assuming they have matching keys (if they don't, just array_values them beforehand):

$array = array();
foreach ($tbDateArr as $key => $value) {
    $array[$value] = $tbTableArr[$key];
}
