http-refer是什么

上一个页面的地址（url），通俗讲就是来源地址。

在PHP中使用$_SERVER["HTTP_REFFER"]可以返回上一个页面的URL，但是前提必须是上一个页面是通过点击超连接或表单提交跳转到本页面的，如果是JS——location.href="本页面地址"，跳转到本页面的话，那么$_SERVER["HTTP_REFFER"]得不到返回值。

这首歌叫作《Going To The Zoo》

Daddy's takin' us to the zoo tomorrow,

Zoo tomorrow, zoo tomorrow

Daddy's takin' us to the zoo tomorrow

And we can stay all day!

We're goin' to the zoo, zoo, zoo

How about you, you, you?

You can come too, too, too

We're goin' to the zoo, zoo, zoo.

See the elephant with the long trunk swingin'

Great big ears and a long trunk swingin'

Snuffin' up peanuts with a long trunk swingin'

And we can stay all day!

We're goin' to the zoo, zoo, zoo

How about you, you, you?

You can come too, too, too

We're goin' to the zoo, zoo, zoo.

See all the monkeys they're scritch scritch scratchin'

Jumpin' around and scritch scritch scratchin'

Hangin' by the long-tail （huff huff huff）

And we can stay all day!

We're goin' to the zoo, zoo, zoo

How about you, you, you?

You can come too, too, too

We're goin' to the zoo, zoo.zoo,

There's a big black bear he's a huff puff a puffin'

His coat's too heavy he's a huff puff a puffin'

Don't get too near the huff puff a puffin'

Or you won't stay all day!

We're goin' to the zoo, zoo, zoo

How about you, you, you?

You can come too, too, too

We're goin' to the zoo, zoo, zoo.

Well the seals in the pool all honk honk honkin'

Catchin' the fish and honk honk honkin'

Little tiny seals all honk honk honkin'

And we can stay all day!

We're goin' to the zoo, zoo, zoo

How about you, you, you?

You can come too, too, too

We're goin' to the zoo, zoo, zoo.

Well we stayed all day and I'm gettin' sleepy

Sittin' in the car gettin' sleep sleep sleepy

Home already gettin' sleep sleep sleepy

'Cause we have stayed all day.

We been to the zoo zoo zoo

So have you you you

You came too too too

We been to the zoo zoo zoo

But, guess what! What!

MOMMY'S TAKIN' US TO THE ZOO TOMORROW!

Zoo tomorrow, zoo tomorrow!

Mommy's takin' us to the zoo tomorrow

And we can stay all day!

We're goin' to the zoo, zoo, zoo

How about you, you, you?

You can come too, too, too

We're goin' to the zoo, zoo, zoo.

We are going to the zoo, zoo, zoo.

How about you, you, you?

You can come too, too, too.

We are going to the zoo, zoo, zoo.
