在 PHP 中,可以使用以下两种方式获取数组的键值对:
1.使用 foreach 循环遍历数组获取键值对
示例代码如下:
$fruits = array("apple" => "red", "banana" => "yellow", "orange" => "orange");
foreach ($fruits as $key => $value) {
echo "The color of the " . $key . " is " . $value . "<br>";
}
输出结果为:
The color of the apple is red
The color of the banana is yellow
The color of the orange is orange
2.使用 array_keys() 函数获取数组的键,使用 array_values() 函数获取数组的值
示例代码如下:
$fruits = array("apple" => "red", "banana" => "yellow", "orange" => "orange");
$keys = array_keys($fruits);
$values = array_values($fruits);
for ($i = 0; $i < count($fruits); $i++) {
echo "The color of the " . $keys[$i] . " is " . $values[$i] . "<br>";
}
输出结果为:
The color of the apple is red
The color of the banana is yellow
The color of the orange is orange
以上两种方式都可以获取数组的键值对,具体使用哪种方式取决于具体情况。
