The ReflectionMethod::export() function is an inbuilt function in PHP which is used to return the export as a string if the return parameter has been set to TRUE, otherwise NULL is returned. Syntax:
string ReflectionMethod::export ( $class, $name, $return )
Parameters: This function accepts three parameters as mentioned above and described below:
- class: This is the name of the initialized class.
- name: This is the name of the method.
- return: It’s value is either TRUE or FALSE. Using TRUE will return the export whereas using FALSE will do the opposite.
Return Value: This function returns the export as a string if the return parameter has been set to TRUE, otherwise NULL is returned. Below programs illustrate the ReflectionMethod::export() function in PHP: Program_1:Â
php
<?phpÂ
// Initializing a user-defined classclass Company {Â
    protected function neveropen($name) {        return 'GFG' . $name;    }}Â
// Using ReflectionMethod() over the class Company$A = new ReflectionMethod(new Company(), 'neveropen');Â
// Calling the export() function$B = $A->export( 'Company', 'neveropen', $return = TRUE );Â
// Getting the export as a string if the // return parameter has been set to TRUE, // otherwise NULL is returned.var_dump($B);?> |
Output:
string(171) "Method [ <user> protected method neveropen ] {
