php-7

问题 I have been trying to understand the chapter Namespaces and dynamic language features from php.net manual. Please consider the following code: namespace Foo; function strstr() { echo "My local ststr method called"; } $a = 'strstr'; $a(); //This would call the global strstr method As per the manual, I have to go $a = 'Foo\strstr' , but I can't find a reason for this. Why can't php interpreter at runtime know that $a = 'strstr'; was defined in the context of namespace Foo , just like executing

问题 I am wondering how the php spaceship operator compares strings, objects and arrays. For example, the below code. echo "Its Me at SO" <=> "Its Me at SO"; will return 0, as i know all characters are same, count is same. But if i have a code like below: echo "Its me at SO" <=> "its Me at so"; It will return 1, means that left side is greater than right side, but how? Is it comparing the ASCII values? Now lets come to arrays. The below code will return 0, as both arrays are equal by count, values

问题 I was wondering if someone may know an alternative to the PHP 5.6.x and higher ... operator (or splat operator I believe its called). What i'm currently doing in my PHP 7 version is: $this->callAction( ...explode('@', $this->routes["authControllers"][$this->routes["uri"][$uri]]) ); The callAction() function takes 2 parameters callAction($controller, $action) but now I need to downgrade the code to PHP 5.4.17. 回答1: Though the splat operator ... is similar to call_user_func_array() : call_user
