我有两个关联数组,我希望与 foreach 循环结合:
$arr1 = array( 'wikipedia.org' => 11, 'bing.com' => 9, 'google.com' => 8, 'blekko.com' => 7, 'groove.com' => 6, 'blo.com' => 5, 'ekko.com' => 4, 'rokko.com' => 3, 'always.com' => 2, 'popo.com' => 1);
$arr2 = array( 'google.com' => 20, 'blekko.com' => 19, 'wikipedia.org' => 8, 'bing.com' => 7, 'blo.com' => 6, 'ekko.com' => 5, 'groove.com' => 4, 'popo.com' => 3, 'always.com' => 2, 'rokko.com' => 1);
我使用一个新数组
$combined = $arr1;
带有 foreach 循环
foreach($arr2 as $key=>$value)
{
array_push($combined,$value);
}
...这增加了价值但不是关键。我想我知道为什么,但找不到添加键和值的方法。这适用于单行,但令人沮丧的是,在 foreach 循环中也不行!
$combined=array_merge(array('blovk.com'=>'44'),$combined);
