How to fix the "headers already sent" error: omit the closing tag in pure PHP scripts

That doesn't work lol

Thanks for helping

Excellent! - exactly what I needed to fix that same error. Thank you.

Great! I remembered seeing this video a long time ago..explain very well the question why it good pratice leave php tags open.👌

The first one with a good explanation. Big Thanks!!!

Great, but php parsing should be smarter than being this buggy. This is just stupid.

Just do it this way
At the top of your file write
?php
Ob_start();
?
Then on your header code
Ob_end_flush();
It will 100% work

thanks

Excellent Excellent. Worked perfectly

ufff thanks...... I was suffering with this problem

The plugin generated 814 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.
i have seen in my plugin , what i should do?

Thanks, so then how do i do redirects?For example once i click a button i need to go to another page? ?

I had a space between the start of the script and the "<?php" tag, like this
<?php

if (isset($_POST['newsletter'])) {

$email = $_POST['email'];
$insert_query = "INSERT INTO `newsletter`(`email`)VALUES ('$email')";
$run_query = mysqli_query($connection, $insert_query);

if ($run_query) {

header('Location: subscribe.php') ;
