## goto

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.

Exemplo #1 goto example

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

O exemplo acima irá imprimir:

    Bar

Exemplo #2 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';
?>`

O exemplo acima irá imprimir:

    j hit 17

Exemplo #3 This will not work

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

O exemplo acima irá imprimir:

    Fatal error: 'goto' into loop or switch statement is disallowed in
    script on line 2

> Nota: The goto operator is available as of PHP 5.3.
