I have a function to process a data file. This process opens the file, and then calls another function to process each entry. This function in turn calls another function to process each line of the entry. A set of fairly complex arrays specifies how all the possible types of entries and lines should be processed, and each function passes sections of these arrays to the next function.
Is it better to pass the parameters by value, in which case they have to be copied into yet more memory when the function is called, or to pass by reference, which I suspect may involve additional overhead every time they are accessed? And is it better to combine several specifications arrays into one more complex array, and pass a single parameter, or to pass them individually as half a dozen different parameters? I suspect that I am probably asking a "how long is a piece of string?" type of question, but are there any general rules which are applicable to this type of situation? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
