Is there a goto statement in php?

In modern programming languages, goto statements are generally considered a very poor implementation method. They may lead to code that is difficult to maintain and can cause code defects. Therefore, some modern programming languages ​​are carefully designed to avoid the use of goto, and PHP is no exception.

Actually, PHP does not have a goto statement. In PHP, the closest translation to jumping to a marker is to use components of a break or continue statement. For example, the following code demonstrates how to use step jumps:

for ($i = 0; $i <p>In this example, we use switch statements and continue/break statements to simulate goto. If in the 2nd iteration of the loop we use a continue statement followed by a labeled number reference, we will skip it at the beginning of the loop (i.e. the 2nd time). When we reach the 6th iteration, we use a break statement, followed by a labeled numeric reference, which will end and exit the loop. </p><p>However, this method is not an elegant implementation, especially in complex code, and it is more troublesome to maintain. So in PHP, goto is considered an anti-pattern rather than a good programming practice. Instead, PHP encourages the use of structured programming practices to ensure code readability and maintainability. For example, by using functional and object-oriented programming to encapsulate and organize code. </p><p>At the end, we can say that although PHP does not support the goto statement, we can simulate the behavior of goto by using other control statements. But that doesn't mean we should use them. Instead, PHP provides ways to avoid using goto to write clean, readable and maintainable code. In order to make the code express the meaning more clearly, we should always use structured programming techniques. </p>
