note 98056 added to control-structures.goto

Better not use it, it has to power to make your code unstructured. To illustrate this danger, I made an especially bad example of using gotos. 
 
<?php
/* Fibonaci and goto */
start:
print  "Please give a number:";
$n = (int)fgets(STDIN) - 1;
if(!isset($x))
        $x = array(1,1);
$last = $i = 0;
$back = 'nextstep';
goto fib;
nextstep:
$t = 0;
$sum = 0;
sum:
print_r($x) ."\n";
if($t > $n){
        goto result;
}
$sum += $x[$t];
$t++;
goto sum;
result:
print "The sum is: " . $sum . "\n";
goto start;
jmpspot:
switch($back){
        case 'nextstep':
                goto nextstep;
                break;
        default:
                goto start;
}
fib:
if($last > $n){
        $i = $n;
        goto jmpspot;
}
if(!isset($x[$i]))
        $x[$i] = $x[$i - 1] + $x[$i - 2];
if($i > $n)
        goto jmpspot;
$last = $i;
$i++;
goto fib;
?>
