拆分两个php标签之间的IF / ELSE语句，给出Parse错误：语法错误，意外$ end

Question

I have built a PHP login system which starts session before loading each page and checks if the user is logged in.

On my Protected page I have a include at the top that starts the session and the if statement as to load the page or not. And then a the bottom I have another include which is the else statement redirecting back to the login page. This works fine when in the page direct, but when included from elsewhere I get this error: Parse error: syntax error, unexpected $end

This is the code

Include 1:

<?php

session_start();

if ($_SESSION['username'])
{
?>

THIS IS THE PROTECTED CONTENT THAT GETS LOADED IF SESSION EXISTS

Include 2:

<?php
}
else
header ("location: index.php");

?>

I think this might be caused by splitting the curly braces on the statement into two PHP tags, the reason why I have done this is to load a whole page if the if statement is true, rather than leaving it in PHP and echoing each line of HTML seperate.

How can I resolve this? or is there a better way for me to split the IF/ELSE statement.

Thanks Danny

Answer 1

Rather than using curly braces, you may try using the colon notation as seen below.

<?php

session_start();

if ($_SESSION['username']):
?>

...

<?php else: header("location: index.php"); endif;
