PHP数组Push数据错误：如何正确向inline_keyboard添加元素

你当前的代码错误在于直接给主数组$customKeyboard追加元素，这会在主数组里新增一个独立的索引项，而不是把元素加入到inline_keyboard子数组中。

正确的追加方式 #

要把新元素添加到inline_keyboard数组里，需要明确指定操作的是这个子数组：

$customKeyboard['inline_keyboard'][] = [["text" => "test", "callback_data" => "test"]];

完整示例代码 #

// 初始化键盘数组
$customKeyboard = [
    "inline_keyboard" => [
        [["text" => "back 🔙", "callback_data" => "back"]]
    ]
];

// 追加新按钮到inline_keyboard
$customKeyboard['inline_keyboard'][] = [["text" => "test", "callback_data" => "test"]];

执行后，$customKeyboard的结构会和你预期的完全一致：

$customKeyboard = [
    "inline_keyboard" => [
        [["text" => "back 🔙", "callback_data" => "back"]],
        [["text" => "test", "callback_data" => "test"]]
    ]
];
