舉個(gè)栗子：$arr = array( '175' => '金針菇'
'100' => '銀針菇');
$arr2 = array( '65' => '白蘿卜'
'67' => '黑蘿卜'
'84' => '黃蘿卜'
'100' => '銀針菇'
'90' => '大蘿卜'
'175' => '金針菇');最后的效果是這樣子滴：$arr3 = array( '175' => '金針菇'
'100' => '銀針菇'
'65' => '白蘿卜'
'67' => '黑蘿卜'
'84' => '黃蘿卜'
'90' => '大蘿卜'
);請教，這樣的算法該怎么實(shí)現(xiàn)？
【算法】數(shù)組中隨機(jī)給定的鍵值對， 置首位， 如何實(shí)現(xiàn)？
