為何這樣總是顯示PHP Notice“Use of undefined constant orange - assumed 'orange' in index.php on line 7”？
<?php //創(chuàng)建一個(gè)關(guān)聯(lián)數(shù)組，關(guān)聯(lián)數(shù)組的鍵“orange”，值是“橘子” $fruit?=?array( ????'applp'?=>?"蘋果", ????'orange'?=>?"橘子"); print_r($fruit); echo?$fruit[orange] ?>

......我搞明白了，[ ]里沒加單引號(hào)
