PHP multiple interfaces The same method _php tutorial

PHP is not allowed if there are multiple interfaces that have an identical method name and are not inherited

The following example:

php; " >

Interface a{

Public function x ();

}

Interface b{

Public function x ();

}

Class C implements a,b{

Public function x ();

}

The following error is reported: Can ' t inherit abstract function b::x () (previously declared abstract in C)

If you want to implement different interfaces with the same method, you can implement the following:

php; " >

Interface d{

Public function x ();

}

Interface a extends d{}

Interface B extends d{}

Class C implements a,b{

Public function X () {

echo "SUCC";

}

}
