# generate a notice for bogus function calls - Thread: https://externals.io/message/19093 - Original archive: https://news-web.php.net/php.internals/19093 - Started by Nuno Lopes on 2005-09-19T21:28:15+00:00 - Messages: 8 - Reply by email to internals@lists.php.net - More for agents: search with https://externals.io/search.md?q={query} · JSON API at https://externals.io/api · documentation at https://externals.io/llms.txt --- ## #19093 — Nuno Lopes — 2005-09-19T21:28:15+00:00 URL: https://externals.io/message/19093#19093 Hi, Although this is not as hot as references or Unicode stuff, I would like to discuss a new topic. Currently PHP accepts more parameters to a function than the required. In English: PHP accepts this and generates no errors. My purpose is to start generating an E_NOTICE, just like we do for not yet initialized variables. This behaviour has already beaten me for a couple of times, because I had a program with functions with similar names, but with different number of parameters. The result for calling the wrong function? A nice infinite loop :) I hope this is not hard to implement (maybe in the parser, to get the errors on compile time - for performance).

Also it makes no sense in an oo-driven environment as long as there is no way of overloading methods. Best way to deal with this is to write gateway methods that delegate to the appropriate methods based on the passed in parameters. --- ## #19095 — ondrej@kmit.sk — 2005-09-19T21:40:12+00:00 URL: https://externals.io/message/19093#19095 · In reply to: #19093 Nuno Lopes wrote: > function a($b) {} > a(1,2,3); > ?> > > PHP accepts this and generates no errors.

You don't need to create functions with variable arguments count like `printf()`? -- Ondrej Ivanic (ondrej@kmit.sk) --- ## #19096 — Nuno Lopes — 2005-09-19T21:45:43+00:00 URL: https://externals.io/message/19093#19096 · In reply to: #19095 > Nuno Lopes wrote: > > […] > > No, stupid output! > > Generating `E_NOTICE` is not a good idea. You don't need to create functions > with variable arguments count like `printf()`? No, I at least I think I've never created such a function. To be sincere, I've not even remembered of such functions when I was writing that e-mail :) So, I think my suggestion is bogus.. Although a special syntax (copied from C) could be introduced.. well maybe not..

This is expected behaviour in PHP! Since PHP does not offer true overloading of method headers (multiple methods or functions with the same name but different parameter lists) this is badly needed.
