goto statement


The goto operator can be used to jump to another section in the program. The target point is specified by a label followed by a colon, and the instruction is given as goto followed by the desired target label. This is not a full unrestricted goto. The target label must be within the same file and context, meaning that you cannot jump out of a function or method, nor can you jump into one. You also cannot jump into any sort of loop or switch structure. You may jump out of these, and a common use is to use a goto in place of a multi-level break.


	      	<?php
			goto a;
			echo 'Foo';
			 
			a:
			echo 'Bar';
			?>
	      

	      	<?php
			for($i=0,$j=50; $i<100; $i++) {
			  while($j--) {
			    if($j==17) goto end; 
			  }  
			}
			echo "i = $i";
			end:
			echo 'j hit 17';
			?>
	      

	      	<?php
			goto loop;
			for($i=0,$j=50; $i<100; $i++) {
			  while($j--) {
			    loop:
			  }
			}
			echo "$i = $i";
			?>
