No PHP connection response

Question

Good evening, could someone help me? I’m doing an academic project where I have to link HTML pages and make them pull information from the database.

So far, I have created a table in my database, created a php script to connect and put the form in the html page as a button. When I click the button it brings me the php code on a web page. Can anyone help me?

Obs: the file is as php and I am opening the web page and on the web page I am pressing the button.

In connection with the BD, you are passing a "variable" $123, but variable names in PHP cannot start with numbers and in this case it is not even being declared. I think you wanted to write $senha. The same goes for $servidor and $usuario.

$link = mysql_connect($servidor, $usuario, $senha);

Also, I don’t know what version of PHP you’re using, but mysql_connect was deprecated in version 5.5.0 and removed in version 7.0.0. From documentation:

This Extension was deprecated in PHP 5.5.0, and it was Removed in PHP 7.0.0

FUNCTION mysqli_connect

You can use mysqli_connect (note the i next to the word mysql - i is of improved/improved).

$link = mysqli_connect($servidor, $usuario, $senha, $banco);

Optionally, you can use mysqli_select_db to connect to the BD. In this case, do not add the parameter $banco in mysqli_connect.

MORE FUNCTIONS

You can search for more functions in the PHP documentation here. There is even the option to use the class mysqli (object orientation).
