To clarify a few things:

We will not download fishy ZIP archives from external websites. If you want help, post your code here on this forum inside a code section. That's the blue “<>” button:
```
This is code
```
We're no machine were you insert broken code and get the repaired code back. We expect you to actively work on the problem and give us a proper description of the issue.
You might want to stop calling people “bro”.

remove db credentials

Strider64 · April 3, 2016

You should be posting a password....leave it blank or put ***** as a replacement.

Jacques1 · April 3, 2016

Change the database credentials immediately, because the posts will still be archived on Google.

As to your problem:

Does the Unix user of the webserver (usually www) have read permission on the shout.php script? Is there any .htaccess file or webserver configuration which blocks access to the script?

Your query is also wide open to SQL injection attacks. Learn to use prepared statements.

my web dont have .htacscess file

Jacques1 · April 3, 2016

You've marked the topic as solved, but appearently you still have the problem. Did you click the button accidentally?

my web dont have .htacscess file

You need to read the other parts of my reply as well.

tamhoangdk · April 3, 2016

its really knew nothing about php . I only know the basics only. or help you to see yourself

Jacques1 · April 3, 2016

Right now, none of your tasks have anything to do with PHP.

So, what are the file permissions? Does the webserver even have read access to the script?

tamhoangdk · April 3, 2016

this all file

tamhoangdk · April 3, 2016

this all files

Jacques1 · April 3, 2016

Check the error log of your webserver. Maybe there's a more detailed error message.

Can your webserver execute any PHP scripts? When you upload a simple "Hello world" script, does that work correctly?

Edited April 3, 2016 by Jacques1

I don't know script simple "Hello world"
