The ReflectionFunction::export() function is an inbuilt function in PHP which is used to return the export as a string if the return parameter is set to TRUE, otherwise NULL is returned.
Syntax:
string ReflectionFunction::export( string $name, string $return )
Parameters: This function accepts two parameters as mentioned above and described below:
- $name: It is the specified function which is to be exported.
- $return: It is the Boolean value either TRUE or FALSE. If its value is set to True then it will export and if its value is set to false then it will return NULL. False is the default value.
Return Value: This function returns the export as a string if the return parameter is set to TRUE, otherwise NULL is returned. Below programs illustrate the ReflectionFunction::export() function in PHP:
