佰佬汇娱乐备用网址PHP array 的加法操作代码

The + operator appends elements of remaining keys from the right handed array to the left handed, whereas duplicated keys are NOT overwritten. 今天 再次看 php manual的时候,才知道 复制代码 代码如下: <?php $a = array("a" => "apple", "b" => "banana"); $b = array("a" => "pear", "b" => "strawberry", "c" => "cherry"); $c = $a + $b; // Union of $a and $b echo "Union of $a and $b: \n"; var_dump($c); $c = $b + $a; // Union of $b and $a echo "Union of $b and $a: \n"; var_dump($c); ?>  When executed, this script will print the following: Union of $a and $b: 复制代码 代码如下: array(3) { ["a"]=> string(5) "apple" ["b"]=> string(6) "banana" ["c"]=> string(6) "cherry" } Union of $b and $a: array(3) { ["a"]=> string(4) "pear" ["b"]=> string(10) "strawberry" ["c"]=> string(6) "cherry" } 原来,我的理解就是。直接把$b中的元素直接复制到$a中。 我错了。
