global variable defined outside a function within a function, we need to add the global keyword before the variable in the function:PHP stores all global variables in an array called $GLOBALS [index]. Index holds the name of the variable. This array can be accessed inside the function, or it can be used to update global variables directly.The above example can be written like this:Static ScopeWhen a function is complete, all its variables are usually deleted. However, there are times when you w

Buy a computer Now, if the computer preinstalled system is WIN8 system, then the default boot mode of this computer should be UEFI mode, now UEFI mode is gradually replacing the traditional mode. UEFI boot requires a separate partition, which separates the system boot files from the operating system itself, which can better protect the boot of the system, this mode can speed up the boot speed and other advantages.Here's how to install the Win7 system on a PC preinstalled with the WIN8 systemBefo
