PHP:将关联数组元素移动到数组的开头

Question

将关联数组的任何元素移动到数组开头的最佳方法是什么？

例如,假设我有以下数组:

$myArray = array(
    'two'   => 'Blah Blah Blah 2',
    'three' => 'Blah Blah Blah 3',
    'one'   => 'Blah Blah Blah 1',
    'four'  => 'Blah Blah Blah 4',
    'five'  => 'Blah Blah Blah 5',
);

我想要做的是将'one'元素移到开头,最后得到以下数组:

$myArray = array(
    'one'   => 'Blah Blah Blah 1',
    'two'   => 'Blah Blah Blah 2',
    'three' => 'Blah Blah Blah 3',
    'four'  => 'Blah Blah Blah 4',
    'five'  => 'Blah Blah Blah 5',
);

Answer 1

这有效:

$myArray = array('one' => $myArray['one']) + $myArray;

Answer 2

如果您有数字数组键并想重新索引数组键,最好将其放入 array_merge这样:

$myArray = array_merge(array($key => $value) + $myArray );
