如何将数组展平为值的字符串? [英] How to flatten an array to a string of the values?

问题描述

我有一个看起来像这样的数组.

I have an array that looks like this.

'keyvals' => 
    array
      'key1' => 'value1'
      'key2' => 'value2'
      'key3' => 'value3'

是否有一种很酷的方法可以将其展平为像'value1 value2 value3'这样的字符串?如果那里有新内容，我也可以使用PHP 5.3.

Is there a cool way to flatten it to a string like 'value1 value2 value3'? I also have access to PHP 5.3 if there's something new there.

推荐答案

$someArray = array(
  'key1' => 'value1',
  'key2' => 'value2',
  'key3' => 'value3'
);
implode(' ', $someArray); // => "value1 value2 value3"
