$a = array (1, 2, 3, 4);
foreach ($a as &$b) $b++;
foreach ($a as $b) $b++;
print_r ($a);

It is increment twice because after the first loop, $b is still a pointer to the fourth element of $a. Continuing in the code, the second loop will assign the fourth value of $a each value of $a, then increment it. Try debugging it like so:

$a = array (1, 2, 3, 4);
foreach($a as &$b){
$b++;
}
print_r($a);
foreach($a as $b){
print_r($a);
$b++;
print_r($a);
}
print_r($a);

... and you will see what it is doing. Solution: unset your variables before you re-use them.

$a = array (1, 2, 3, 4);
foreach ($a as &$b) $b++;
unset ($b)
foreach ($a as $b) $b++;
print_r ($a);

And for the $$ thing, it seems to do exactly what it is intended for...

[Simple]
$a = "Hello World";
$b = "a";
echo $$b;
//outputs 'Hello World'

[Complex]
$var0 = "Hell";
$var1 = "o wo";
$var2 = "rld!";
$i = "var0";
while(intval($i[3]) <= 2){
echo $$i;
$i[3] = intval($i[3])+1;
}
//outputs 'Hello World!'

"Can the owner of a gun shop be charged as an accessory if a gun they sold is used in a murder?" Yep. If I go to a gun shop and say 'I need a gun, so I can kill someone,' then I am sold a gun, you bet that gun show owner is an accessory.

Porn

On: Site Says 'Go Away!'; Federal Court Says No

So, If I were still under 18, and I went to a free porn site that prompts me to verify that I am indeed 18, then I would not be legally bound to tell the truth? And if I lie, then aqire access to the site and my parents were to decide to sue the website operators for providing me with such content, how would the courts rule?

Define 'broken'. If a file is stored in a multi-part RAR Archive with passworded encryption, is it not broken? It is an absolutly useless packet of data to anyone without the password to extract it. And when its downloaded as a broken file collection, and then extracted and watched, where is the point at which it becomes illegal? Is it illegal to download the 'broken' file, or is it illegal to extract and watch it? And if it's only illegal to extract/watch the file, then is it not illegal to upload the 'broken' file?
