If for different situations, need to perform different established operations, if or according to the normal execution process, is unable to complete the task, this time, it is necessary to introduce the concept of process jump, using the process jump statement goto. The meaning of a process jump is to change the default order of execution, forcing the jump to the specified location to execute a particular block of the program. Let's take a look at a
If you need to execute different established operations for different situations, but you still need to follow the conventional execution process, the task cannot be completed. In this case, you need to introduce the concept of process redirection, use the process jump statement Goto. The default execution sequence is changed to force the jump to the specified position to execute a specific Program Block. Let's look at an example: assume that you

Timely and effective jump will help improve program execution efficiency ----------------------------------------------------------- the break statement is used to terminate the recent closed loop or the switch statement where it is located.

This afternoon I encountered a problem where I used the branch clause in the following sentence. I want to jump out of the Branch and the cycle in the branch. I didn't want to use the Skip phrase for a moment. So I found some information on the Internet. This article Article Think it is not necessary.

Break: Terminates the loop of this layer; A number can be followed by a break, which means that several layers of loops are terminated. Break 3 to terminate the 3-layer loop.2, continue: skip this cycle; Continue can also be followed by numbers, which means skipping several layers of loops3, return: Terminates the current function, and returns the value (if any), but gen
The goto syntax for PHP can jump to a specified location, as shown in the code, goto display, which defines a display after the code, so that when the goto display statement is executed, it jumps to the place where the display is defined, This is PHP5.3 added syntax to support PHP7.

I. Goto plotGoto, perhaps equivalent to a series of dinosaurs that used to run across the Earth, is just like a dinosaur, and finally becomes extinct. Teacher dijstra was the first to take a picture of Goto and beat the danger of the command. As we can see some code feelings: the person who writes the code is good, and the person who maintains the code is crying. I once caught the tail of the basic language
. Continue Statement Form: continue;2. Continue statement function:It can only appear in the loop body. Its function is to immediately end this loop, that is, when a continue statement is encountered, the statement after the continue in the loop body is not executed, immediately go to determine whether the cycle condition is set, that is, stop the current cycle and enter the next cycle.3. the difference between a continue and a break statement: A continue only ends this loop, rather than termina
