PHP goto Statement: Functions & Uses

The goto statement in PHP is used to control the flow of a program by jumping to a specific labeled position. It provides functionality such as:

1. Jump to a specified label position: The goto statement can directly jump to a specified label position, therefore changing the flow of program execution.
2. Break out of multiple loops: Using the goto statement in nested loop structures can easily break out of multiple loops to reduce the complexity of the code.
3. Simplify code logic: in certain situations, using a goto statement can simplify code logic, making the program easier to understand and maintain.

While the goto statement can conveniently alter the flow of a program in certain situations, its tendency to cause confusion in code structure and make maintenance difficult means it should be avoided as much as possible in practical development.
