将更多键和值放入现有数组中

问题描述：

I have an array like so:

$json = array('error'=>true);

But I'd like to perhaps add more keys and values to this at a later time. My feeble knowledge tried this:

$json .= array('something'=>'else');

Which doesn't work. I found array_push but it seems this is for just pushing in new values - not keys. How is this achieved so that with 2 separate declarations I end up with the equivalent of:

$json .= array('error'=>true,'something'=>'else');

我有一个这样的数组： p>

  $ json =  array（'error'=＆gt; true）; 
  code>  pre> 
 
 但是我想在以后添加更多的键和值。 我的微弱知识尝试了这个： p> 
 
 
  $ json。= array（'something'=＆gt;'else'）; 
  code>  pre> 
 \  n 哪个不起作用。 我找到了 array_push  code>，但似乎只是推送新值 - 而不是键。 如何实现这一点，以便使用2个单独的声明，最终得到相当于： p> 
 
 
  $ json。= array（'error'=＆gt; true，'something'=  ＆gt;'else'）; 
  code>  pre> 
  div>

答

there are many ways to accomplish this:

$json['keyname'] = 'something
$json[] = 'something' <- numerical incremented key
array_push($json, 'value') <- same as above
$json = array_merge($json, $some_other_array) <- mixes the two arrays together

Just keep in mind that arrays are not strings
