Overload and override in PHP and JAVA

PHP does not support methods and operator overloading. JAVA does not support overload of operators (but "+" is actually an operator overload): In the same class, functions with the same name, return values or parameter types, different numbers are called overloading.
Overwrite: a function with the same name. it is of the same return value type and the same parameter is called overwrite. It refers to the subclass override of methods in the parent class.
PHP does not support methods and operator overloading. JAVA does not support operator overloading (but "+" is actually an operator overload ).
The code is as follows:
Class Father {
Public function fmeth1 (){
Echo "fmeth1 ()...
";
}
// Public function fmeth1 ($ str1 ){
// Echo "fmeth1 () with $ str1...
";
/
