<p>I've heard rumors that PHP is planning on introducing a "goto" command. What is it supposed to be doing?</p>

<p>I've tried searching a bit, but haven't found anything awfully descriptive. I understand that it won't be a "<code>GOTO 10</code>"-like command...</p>

Granted, I am not a PHP programmer, and I don't know what PHP's exact implementation of GOTO will look like, but here is my understanding of GOTO:
GOTO is just a more explicit flow control statement like any other. Let's say you have some nested loops and you only need to find one thing. You can put in a conditional statement (or several) and when conditions are met properly, you can use a GOTO statement to get out of all the loops, (instead of having a 'break' statement at each level of nesting with a conditional statement for each. And yes, I believe the traditional implementation is to have named labels that the GOTO statement can jump to by name. You can do something like this:
```
```
for(...) {
    for (...) {
        for (...) {
        // some code
        if (x) GOTO outside;
        }
    }
} 
:outside
```
```
This is a simpler (and more efficient) implementation than without GOTO statements. The equivalent would be:
```
```
for(...) {
    for (...) {
        for (...) {
            // some code
            if (x) break;
        }
        if(x) break;
    }
    if(x) break;
}
```
```
In the second case (which is common practice) there are three conditional statements, which is obviously slower than just having one. So, for optimization/simplification reasons, you might want to use GOTO statements in tightly nested loops.
