在PHP中向子数组添加一个数组元素

Question

我有

$statement = Array
(
    [0] => Array
        (
            [red] => 06-01-2012
            [green] => 436
            [blue] => MEDIA
            [black] => 2006
        )

    [1] => Array
        (
            [red] => 06-01-2012
            [green] => 430
            [blue] => MEDIA
            [black] => 2007
        )

);

我想通过像 $statement[1] 这样的东西向数组1中添加 [flex] => 1。我尝试过使用数组合并，但它们已经将数组0和1组合在一起。基本上，我想添加到最新的一个。

Answer 1

如果我理解正确的话，请尝试以下方法：

$statement[count($statement)-1]['flex'] = 1;

Answer 2

<?php
$statement = array(
    array(
            "red" => 06-01-2012,
            "green" => 436,
            "blue" => "MEDIA",
            "black" => 2006
        )

    ,array(
            "red" => 06-01-2012,
            "green" => 436,
            "blue" => "MEDIA",
            "black" => 2006
        )

);

echo "<pre>";
print_r($statement); //first

$statement[1]["flex"] = 1;

print_r($statement); //second
?>
