We will explore here how we can call overridden static functions from the base class If that function is overridden by the derived class.<\/p>\n\n\n\n

Lets understand it with an example of problem and solution code –<\/p>\n\n\n\n

What’s The Problem ?<\/h4>\n\n\n\n

Suppose you create two static methods in a class BaseClass<\/strong>.
You have called the first static method getStaticText() from the second static method getStaticResult().<\/p>\n\n\n\n

Now a child class DerivedClass<\/strong> extends the BaseClass<\/strong> and override the static method getStaticText()<\/strong>.<\/p>\n\n\n\n

See the below piece of code to understand it properly –<\/p>\n\n\n\n

<?php\n\tClass BaseClass \n\t{\n\t    \/\/ Static functions\n\t    public static function getStaticText()\n\t    {\n\t        return 'Called from BaseClass';\n\t    }\n\n\t    public static function getStaticResult()\n\t    {\n\t        \/\/ we can alternatively use BaseClass::getStaticText();\n\t        return self::getStaticText();\n\t    }\n\t}\n\n\tClass DerivedClass extends BaseClass\n\t{\n\t    public static function getStaticText()\n\t    {\t\n\t        return 'Called from DerivedClass';\n\t    }\n\t}\n\n\tvar_dump(DerivedClass::getStaticResult());\n\n?>\n<\/pre>\n\n\n\n
<\/p>\n\n\n\n
Now if you call getStaticResult()<\/strong> from DerivedClass <\/strong> –<\/strong><\/p>\n\n\n\n
then the result of var_dump(DerivedClass::getStaticResult())<\/strong> will be :<\/p>\n\n\n\n
 “Called from BaseClass<\/strong>“.<\/p>\n\n\n\n
The getStaticText() function called from BaseClass as it is called with self keyword.<\/p>\n\n\n\n
Case :<\/h4>\n\n\n\n
You have overrided the getStaticText() method in the DerivedClass.<\/p>\n\n\n\n
Also you have called the method from DerivedClass  – var_dump(DerivedClass::getStaticResult());<\/p>\n\n\n\n
Here Let’s suppose<\/strong> you want,  if any method is overridden in the child class then it must be called from the child class. <\/em><\/strong>If calling class is child class (DerivedClass).<\/p>\n\n\n\n
In the above code I want getStaticText()<\/em><\/strong> must be called from DerivedClass.<\/em><\/strong><\/p>\n\n\n\n
