• PHP is messing with HTML Design & Displaying results outside of the HTML 1 answer

I have a class

$page=new page;

with function,

header() {
echo 'blah blah';
}

now if I concat two strings together like,

$string= "";
$string .= " 1234";
$string .= $page->header();
echo $string;

results in,

blah blah 1234

how can I get it in the correct order?

</div>

Answer 1

You're just echoing the string.

your header() function should return a string:

function header() {
    return 'blah blah';
}
