[13] As in C, variables may be cast to a specific type by prefixing the type in parentheses. PHP treats newlines as whitespace, in the manner of a free-form language.
MS-DOS and Unix consoles are examples of these types of windows. Terminal windows often conform to the hotkey and display conventions of CRT-based terminals that predate GUIs, such as the VT-100. A child window opens automatically or as a result of a user activity in a parent window. Pop-up windows on the Internet can be child windows.
In computer programming, a static variable is a variable that has been allocated "statically", meaning that its lifetime (or "extent") is the entire run of the program. This is in contrast to shorter-lived automatic variables, whose storage is stack allocated and deallocated on the call stack; and in contrast to dynamically allocated objects, whose storage is allocated and deallocated in heap ...

Luke Wroblewski has summarized some of the RWD and mobile design challenges and created a catalog of multi-device layout patterns. [15] [16] [17] He suggested that, compared with a simple HWD approach [clarification needed], device experience or RESS (responsive web design with server-side components) approaches can provide a user experience that is better optimized for mobile devices.
