Multiple explode cutting and combination, what should be done?

$a = ' youku$$ $tudou $$ $down '
$b = ' first episode $ABCD

The hyperlink output is wrong.

Wrong? Where is it wrong?
I can't get out of it, can I?

The hyperlink should be
Youku
1_1.html
1_2.html
1_3.html
``````````

Tudou
2_1.html
2_2.html
2_3.html
```````````

Down
3_1.html
3_2.html
3_3.html
`````````

Multiple loops output I don't know what to do.

The page should be real and should be filled in the ABCD location of your data
How can the dynamically generated and real pages correspond?

*_*.html
(Here is an array of Youku Tudou down) _ (here is the ID of each group and re-corresponds). html

Change to this, the link name is wrong, the array of hyperlinks can start from 1, not from 0?

$a = ' youku$$ $tudou $$ $down '; $b = ' first episode $ABCD first episode $ABCD second episode $abcd third episode $abcd fourth episode $ABCD fifth episode $abcd$$$ sixth episode $ABCD seventh set $ABCD eighth set $DDDDD Nineth set $ ABCD Tenth Episode $ABCD 11th episode $abcd$$$ 12th episode $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 = ' youku$$ $tudou $$ $down '; $b = ' first episode $1_1.html second episode $1_2.html third episode $1_3.html fourth episode $1_3.html fifth episode $1_5.html$$$ first episode $2_1.html second episode _2.html Third Episode $2_3.html fourth episode $2_4.html fifth episode $2_5.html$$$ the first episode $3_1.html the second episode $3_2.html the third episode $3_3.html fourth episode $3_4.html fifth set $3_5.html '; $a = explode (' $$$ ', $a), $b = explode (' $$$ ', $b), foreach ($a as $i + = $r) {  echo "
$r

Thank you so much

In fact, this is a play address, ABCD is the playback address, to do it with another
