I do admit this question is going to be a bit vague, but I will try to explain what I'm trying to accomplish by a few examples. I have some PHP code that loads a bunch of variables from the MySQL database, contains some declarations, some functions to quickly output HTML code etc. However I would love to do all that stuff before anything is sent to the client.
So I do:
<?php
include("somefile.inc");
function bla()
{
...
}
if (fails)
echo "Error: ...<br />";
?>
<!DOCTYPE>
<html>
<head>
<script>
...
<?php echo $someString; ?>
...
</script>
</head>
<body>
...
</body>
</html>
This is all fine and ok, until I get an error. The echo will not show in the browser because it's before all HTML... So I modified:
<!DOCTYPE>
<html>
<head>
<script>
...
<?php echo $someString; ?>
...
</script>
</head>
<body>
<div class="error_block">
<?php
include("somefile.inc");
function bla()
{
...
}
if (fails)
echo "Error: ...<br />";
?>
</div>
...
</body>
</html>
Now I can actually see errors, which is good. But now the problem arises that in the header, or scrips, I cannot access variables that will be loaded later on in the newly created error_block.
I really don't like splitting the code in the error_clock to some above the HTML document and some in the error_block. And I also don't want to use PHP's die() function which abrubtly ends the execution.
Anyone can give their 2 cents on this issue? Thanks.

If you're looking for an alternate solution, I have one for you. What I like doing is having the logic in before the DOCTYPE
if(error) { $error = "Please do something" }
Than, down in the document I have a div just for the error (Thanks @Dave for the input)
<?php echo $error != '' ? '<div id="error">' . $error . '</div>' : ''; ?>
This div will not appear if there isn't an error (meaning $error is empty) and it makes it easier for you to style the error message the way you would like
#error { color:red; }
If you want to get fancy, you can use some jQuery to hide/show the div so that the error doesn't have to persist.
$('#error').show().delay(7000).fadeOut();
