goto example

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';
?>



The above example will output:

Bar

goto loop example
<?php
for($i=0,$j=50; $i<100;$i++) {
while($j--) { if($j==17) goto end;
}
}
echo "i = $i"; end: echo 'j hit 17'; ?>  The above example will output: j hit 17  This will not work <?php goto loop; for($i=0,$j=50;$i<100; $i++) { while($j--) {
loop:
}
}
echo "$i =$i";
?>



The above example will output:
