How can I format an error message and prevent going out off page while it occures? 2

Hi everyone,
Here is a simple PHP code aimes to connect into a MySql server.
I'm trying to format error messages in a way my page will continue working despite errors that occure.

<?php
$con=mysqli_connect("localhost","root","root4qpines","tivonidb");
if (mysqli_connect_errno($con))
  {
       echo
       '<p class="SQLerror">';
            echo "Failed to connect to MySQL: " . mysqli_connect_error();
            echo
        '</p>';
  }
else
  {
       echo
       '<p class="SQLerror">';
         echo "Success connecting to MySQL! " ;
         echo 
       '</p>';
  }
?>

Here's the css code:

p.SQLerror
	{
		width:447px;
		height:363px;
		background-color: #fd0303;
	}

In return I get error message that takes me out of my page and is inconsistent with the css

Put the error code in the html for the page rather than before the page outputs starts to be served.

There are different types of errors. Fatal and non Fatal. Usually Fatal errors will stop execution as the code cannot continue after those errors.

What exactly are you getting instead of your styled error?

Also where in your page is this error? As Chris suggests if the PHP code runs before the HTML and by extension the CSS is loaded you probably won't get your styled error message.

Also if your PHP installation is set to display errors it will do so regardless of what you code. You can append a "@" (at symbol) to your function calls to suppress error display, but for production servers its best to set PHP.ini to not display errors, and instead have it log them to a file you can check later.

Note that if your let your page continue, and the rest of your code is dependent on the mysql connection you may get additional errors further down. Its best to maybe stop execution at that point of the PHP script and simply echo out a user friendly notice.

Thank you both. I'll try your suggestions later, hopefully I'll not come back with further questions.
