PHP数组运行函数并将变量传递给它

I am coding a bot for a game and I am now coding the handlers I want to call my array so it runs the function.

$handlers = array(
    "x" => function()
);

function function($m)
{
    echo "Var: " . $m . "
";
}

When I call handlers I tried it like this:

$handlers("x");

So how can I pass the variable to the function.

    What you need is the call_user_func function. Besides, in your $handlers array, the name of the function must be in quotation marks and you can not use the reserved keyword function as the name of the function! and you may access the array element using [] operator:

    $handlers = array(
        "x" => '_function'
    );
    
    function _function($m)
    {
        echo "Var: " . $m . "
    ";
    }
    
    call_user_func($handlers['x'], "hello :)");
