将对添加到PHP数组的最简单方法

Question

我想用PHP将数组附加到数组中， 这就是我现在拥有的;

pairs[0]['key1'] = 'something1';
pairs[0]['key2'] = 'something2';
pairs[1]['key1'] = 'other1';
pairs[1]['key2'] = 'other2';
pairs[2]['key1'] = 'thing1';
pairs[2]['key2'] = 'thing2';

有没有办法不必指定索引？ 即伪代码;

pairs[] = [key1=something1,key2=something2]

Answer 1

for ($i=0;$i<=10;$i++){
    $arr[] = array("key"=>$i,"info"=>"something" . $i);
}
print_r($arr);
// output => Array ( [0] => Array ( [key] => 0 [info] => something0 ) [1] => Array ( [key] => 1 [info] => something1 ) [2] => Array ( [key] => 2 [info] => something2 ) ) ... 

Answer 2

array_push()可以满足您的需求

array_push($pairs, array('key1' => 'something1', 'key2' => 'something2'))

Answer 3

也许试试：

$pairs[]=array(key1 => "something1", key2 => "something2")

或

$pairs[]=array_combine(array("key1","key2"),array("something1","something2"));
