PHP，是否有可能，如果它是一个简单的过程，如何覆盖美元符号，$？

Question

I was wondering if it's possible to overwrite the dollar sign in php (the one that prefixes variable names, like $var ). I am wondering if I can overwrite it to something like the pound sign (£), a Chinese symbol, or perhaps the number sign (#), for £var ,木var , or #var .

Answer 1

You certainly could. You would need to download the PHP source, and modify the parser to support this instead. Not trivial, but a possibility due to the fact that PHP is open source.
