I don't want this exec line to become extremely long and unmanageable. I have also explored passing a php array instead of a variable with the following code: $checked = array( "key1" => "1" "key2" => "1" "key3" => "1" ); $checkedJson = json_encode($checked); $tmp = exec(

The requests can be to an arbitrary domain with arbitrary parameters. I'm sending a request to my domain containing the target encoded as a GET parameter, i.e. GET https://www.example.com/proxy/?url=http%3A%2F%2Fnginx.org%2Fen%2Fdocs%2Fhttp%2Fngx_http_proxy_module.html Then in Nginx I do location /proxy/ { resolver 8.8.8.8; set_unescape_uri $dst $arg_url; proxy_pass $dst; } This works for single files, but the target server sometimes returns a

I have this: def method a = [1,2,3] yield(*a) p a end method {|x,y,z| z = 0} #=> this puts and returns [1, 2, 3] (didn't modified the third argument) How can I pass these arguments by reference? It seems to work if I pass the array directly, but the splat operator would be much more practical, intuitive and maintainable here. 回答1: In Ruby when you write x = value you are creating a new local variable x whether it existed previously

I have to be sure the function doesn't edit the contents. Thank you very much. 回答1: I have to be sure the function doesn't edit the contents Unless the function takes a const parameter, the only thing you can do is explicitly pass it a copy of your data, perhaps created using memcpy . 回答2: You can use const void foo(const char * pc) here pc is pointer to const char and by using pc you can't edit the contents. But it doesn't guarantee

I could rename the constructor to something else and call it manually but i would like a
