Wrong? What's wrong?
I cannot always be born out of nothing, right?

The hyperlink should be
Youku
Authorization 1.html
1_2.html
Routing 3.html
"""'

Tudou
2_1.html
2_2.html
2_3.html
"""''

Down
3_1.html
3_2.html
3_3.html
"""

I don't know how to implement multiple loop outputs.

The page should be real and should be filled in the abcd location of your data
How can dynamic generation correspond to real pages?

* _ *. Html
(Here is the first batch of youku tudou down_(this is the unique id).html of each group.

In this case, the link name is incorrect. Can the hyperlink array be counted from 1 instead of 0?

$ A = 'youku $ tudou $ down '; $ B = 'Episode 1 $ abcd episode 1 $ abcd episode 2 $ abcd episode 3 $ abcd episode 4 $ abcd episode 5 $ abcd $ episode 6 $ abcd episode 7 $ abcd episode 8 $ ddddd ninth set $ abcd tenth set $ abcd 11th set $ abcd $ 12th set $ abcd 13th set $ abcd 14th set $ abcd 15th set $ abcd 16th set $ abcd 17th set $ efghijk '; $ a = explode ('$', $ a); $ B = explode ('$', $ B ); foreach ($ a as $ I => $ r) {echo"

But your data is supposed to be like this.

$ A = comment'; $ a = explode ('$', $ a); $ B = explode ('$', $ B ); foreach ($ a as $ I => $ r) {echo"
$ R
\ N "; foreach (explode (" \ n ", $ B [$ I]) as $ v) {$ t = explode ('$ ', trim ($ v); echo "$ t [0] \ n ";}}

Youku

Tudou
First set second set third set fourth set fifth set
Down
First set second set third set fourth set fifth set

Thank you very much.

In fact, this is the stream playback address. abcd is the stream playback address, which must be used separately.
