PHP Array Values: How to Access Elements

In PHP, you can access the values of elements in an array using indexes. For example, if you have an array named $fruits and you want to access the value of the first element, you can use the following code:

$fruits = array("apple", "orange", "banana");
echo $fruits[0]; // 输出: apple

You can also use a foreach loop to iterate through each element in the array and access its value. For example:

$fruits = array("apple", "orange", "banana");
foreach($fruits as $fruit){
    echo $fruit . "<br>";
}
// 输出:
// apple
// orange
// banana

Another way is to use an associative array, where each element has a key and a value. You can access the value of an array element by its key. For example:

$fruit_colors = array("apple" => "red", "orange" => "orange", "banana" => "yellow");
echo $fruit_colors["apple"]; // 输出: red
