Introduction and usages of PHP Goto statement

This article mainly introduces what is the PHP goto statement and goto operator usages, need friends can refer to the following

The goto operator can be used to jump to a specified position in a program. The target location can be marked with a colon for the target name. The Goto in PHP has a certain limit and can only jump in the same file and scope, which means you can't jump out of a function or class method, and you can't skip to another function. You also can't jump into any loops or switch structures.   A common use is to jump out of loops or switch, instead of multiple layers of break. The usage is very simple: goto after the flag with the target position, in the target location with a colon marked with the target name, as follows: The code is as follows: <?php goto A;   Echo ' Foo ';//This sentence is skipped over A:echo ' Bar ';   The above example outputs the result: Bar;    For ($i =0, $j =50 $i <100; $i + +) {while ($j-) {if ($j ==17) goto end; } echo "i = $i";   End:echo ' J hit 17 '; The above example outputs the result: The J hit?> note:the goto operator is valid only in PHP 5.3 and above.
