...ments something called "copy-on-write" so that $foo = $bar doesn't need to allocate extra memory straight away) or because they have been assigned (or passed to a function) by reference (e.g. $foo =& $bar). So a zval has no name. When you pass a parameter to a function you are creating a new var...

...tice under any circumstances. Here's how: explode is limited to return 3 tokens (so that if the input is "1-2-3-4", $d will become "3-4") ctype_digit is used to make sure that the input does not contain any non-numeric characters (apart from the dashes) array_pad is used (with a default value that...

...ur and pretty dodgy to rely on. GOFORIT (or other random arbitrary invalid token) is deliberately breaking a security measure applied by a server; if you have control of the server yourself (which you should do for any real public service) then the correct thing to do is just set the server not to s...

...arge number of inodes used even if the disk is not very full. An inode is allocated to a file so, if you have gazillions of files, all 1 byte each, you'll run out of inodes long before you run out of disk. It's also possible that deleting files will not reduce the inode count if the files have mul...

...p can broadcast messages to the socket. the socket will inspect the signed token, and if it passes, ti will then broadcast the message. this is good for preventing spam and ensure data integrity. so never post directly to the node socket from the client. instead post to php app with ajax, then relay...

... at runtime, it usually has an advantage of not requiring excessive memory allocations (this depends on your compiler and runtime). That said, unless performance is your only end goal and you are in the critical path then you should really favour the safer (slower) methods. There is a very deliciou...
