PHP或运算符类似于javascript？ 有一个简单的方法吗？

Question

In javascript I can pass an object literal to an object as a parameter and if a value does not exist I can refer to a default value by coding the following;

this.title = params.title || false;

Is there a similar way to do this with PHP?

I am new to PHP and I can't seem to find an answer and if there is not an easy solution like javascript has, it seems pure crazy to me!!

Is the best way in PHP to use a ternary operator with a function call?

isset($params['title']) ? $params['title'] : false;

Thanks

Don't look for an exact equivalent, because PHP's boolean operators and array access mechanism are just too different to provide that. What you want is to provide default values for an argument:

function foo(array $params) {
    $params += array('title' => false, ...);

    echo $params['title'];
}
