Modify definition.php file with php form

[dragon_sa]

I have seen how to change an existing file using the text area, but how would you just extract and edit the variables of the defines tags in file of php defines statements, for use for example to modify site logos and heading texts that are defined in such files? Any help would be much apreciated thank you

someone has mentioned about using

get_defined_constants() which will list all define( 'LABEL', 'value' );

 

but not sure how to use it

 

Form page reading file and listing seleced defines values in text area box, which can be changed, on submit it updates the definition.php file with the new values for the selected LABELS, any help on this please
