functions expect a 'duplicate' argument. When should I set this to 1 and when to 0?

First of all, it definitely matters. Sending the right value is extremely important. If you send 1 instead of 0, then you would get a memory leak. If you send a 0 instead of 1, you'll most likely crash. So you really must send the right values each time :) [...] So what you're saying is - if duplicate is set to 0, you create a reference - if duplicate is set to 1, you increase the reference counter so that 'duplicate' means 'I am a duplicate', instead of what I first thought 'duplicate me' (which is why I sent a 1 first (duplicate me), and a 0 second).

No, it's not clear I guess :) 'duplicate' does mean 'duplicate me'. If duplicate is set to 0, then you tell the engine not to duplicate the string, but use it as-is. If it's set to 1, then you tell the engine to duplicate it, because this string is either static, or already referenced by other things in PHP. Zeev
