for($x=0;$x<10;$x++) {
print "hello ";
}

$x = 0;
LABEL_1:
print "hello ";
$x++;
while ($x<10) { goto LABEL_1; }

$x = 0;
LABEL_1:
print "hello ";
$x++;
if ($x<10) { goto LABEL_1; }

$x = 0;
LABEL_1:
print "hello ";
$x++;
if ($x<10) { goto LABEL_2; }
goto LABEL_1;
LABEL_2:

$x = 0;
LABEL_1:
print "hello ";
$x++;
if ($x==10) { goto LABEL_2; }
goto LABEL_1;
LABEL_2:

$x = 0;
LABEL_1:
print "hello ";
$x++;
while ($x<10) { goto LABEL_1; }

$x = 0;
LABEL_1:
print "hello ";
$x++;
if ($x<10) { goto LABEL_1; }

$x = 0;
LABEL_1:
print "hello ";
$x++;
if ($x<10) { goto LABEL_2; }
goto LABEL_1;
LABEL_2:

$x = 0;
LABEL_1:

if ($x==10) { goto LABEL_2; }
goto LABEL_1;
LABEL_2:
