Question

I have an array that looks like this.

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

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.

Answer 1

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