在单行上回显数组的键？ PHP

Question

如何在一行上获得数组键的回声？

[The] => s
[revelation] => b
[that] => z
[the] => d
[Star] => e  
[Wars] => h    

结果：

<p>The revelation that the Star Wars.</p>

Answer 1

非常简单：

$myArray = [
    'The' => 's',
    'revelation' => 'b',
    'that' => 'z',
    'the' => 'd',
    'Star' => 'e',
    'Wars' => 'h',
];

echo implode(' ', array_keys($myArray));

这基本上得到一个键的数组，然后用空格内容。
