浅析php将数据转为数组类型的方法

$colors = array("Red", "Green", "Blue");

print_r($colors);

Array
(
    [0] => Red
    [1] => Green
    [2] => Blue
)

$str = "Hello World!";
$arr = explode(" ", $str);
print_r($arr);

Array
(
    [0] => Hello
    [1] => World!
)

$colors = array("Red", "Green", "Blue");
$str = implode(", ", $colors);
echo $str;

$json_str = '{"name": "John", "age": 30, "city": "New York"}';
$arr = json_decode($json_str, true);
print_r($arr);

Array
(
    [name] => John
    [age] => 30
    [city] => New York
)

$arr = range(0, 5);
print_r($arr);

Array
(
    [0] => 0
    [1] => 1
    [2] => 2
    [3] => 3
    [4] => 4
    [5] => 5
)

$arr = array("Red", "Green", "Blue");
list($a, $b, $c) = $arr;
echo $a . ", " . $b . ", " . $c;

$arr = file("data.txt");
print_r($arr);

Array
(
    [0] => Line 1
    [1] => Line 2
    [2] => Line 3
)
