Solution to the Problem To solve this problem, we have to store the header in a buffer and send the buffer at the end of the script, so to store the header in the buffer, we will use the php ob_start() function and to clean the buffer, we will use the ob_end_flush() function. See the below code snippet. This is it!
Basically, there are two types of header calls. One is header which starts with string “HTTP/” used to figure out the HTTP status code to send. Another one is the “Location” which is mandatory. replace: It is optional which indicates whether the header should add a second header or replace previous.
The header() function in PHP sends a raw HTTP header to a client or browser. Before HTML, XML, JSON, or other output is given to a browser or client, the server sends raw data as header information with the request (particularly HTTP Request).
The header() function is an predefined PHP native function. With header() HTTP functions we can control data sent to the client or browser by the Web server before some other output has been sent. The header function sets the headers for an HTTP Response given by the server.
That is because you have an output:
?> <?php results in blank line output.
header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP
Combine all your PHP codes and make sure you don't have any spaces at the beginning of the file.
also after header('location: index.php'); add exit(); if you have any other scripts bellow.
Also move your redirect header after the last if.
If there is content, then you can also redirect by injecting javascript:
<?php echo "<script>window.location.href='target.php';</script>"; exit; ?> Try adding ob_start(); at the top of the code i.e. before the include statement.
