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

Excellent explanation and demonstration.

Peachy!

May I ask what editor is your fav for php?

Dave is the most brilliant PHP teacher so far ..ill definitely buy another course from him once i'm through with this PHP course

I'm still getting error can you please help me ??

This is the code

<?php

require_once "database/dbConnection.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') ;
}
else {
$error = "Email Already Exists!";
}

}

?>

I already use ob_start(); and ob_end_flush();

thanks this error was bugging me a lot

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

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.

thank you.

great you make my day!

Thank you so much sir...

It was really helpful, Thanks mate

Excellent Excellent. Worked perfectly

thanks

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

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

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