php – Cannot modify header information – headers already sent by (php header already sent error)
This error comes when you print any thing before php hreader command
Example Error Code:
<?php
print “text”;
header(‘Location: http://www.example.com/’);
?>
Solution :
<?php
function FunJavaScriptRedirection($url)
{?>
<script type=”text/javascript”>
<!–
window.location = “<?=$url?>”
//–>
</script>
<?}
print “test”;
FunJavaScriptRedirection(“http://www.example.com/”);
?>

There are 5 houses in five different colors
In each house lives a different nationality.
These 5 owners drink a certain beverage, smoke a certain brand of cigar and keep a certain pet.
No owners have the same pet, smoke the same brand of cigar, or drink the same beverage.
The CLUES:
The Brit lives in the Red house.
The Swede keeps dogs as pets.
The Dane Drinks tea.
The Green House is on the left of the White House.
The Green House’s owner drinks coffee.
The person who smokes Pall Mall rears birds.
The owner of the yellow house smokes Dunhill.
The man in the center house drinks milk.
The Norwegian lives in the first house.
The man who smokes Blends lives next to the one who keeps cats
The man who keeps horses lives next to the man who smokes Dunhill.
The man who smokes Blue Master drinks beer.
The German smokes Prince.
The Norwegian lives next to the Blue House.
The man who smokes Blends has a neighbor who drinks water.
The QUESTION:
Who owns the fish?

[…] Then, you need to check to see if you are using header() before any output is sent. For example, the php.net gives some examples. Here’s another example. […]

Above code is enogh to page redirect. Some code is not working on firefox mozilla.
So, other option is internet explore. Every time it should be work and it is working.
A programmer should not be copy the code from the internet.
Brian said
This NOT a solution to the problem.
It is a workaround which only avoids the problem if the user has js activated.

sushil karki said
just use ob_start() in the begining of the page. no need of javascript.
miff said
Use ob_start() at a very top of your script, and after header(…) use ob_end_flush().
Works great, JS is good but when user disable js…

Ya, it really helps me. Thanks a lot for your post.
mediafirehunt said
Solution is very simple. dont change anything on your script,
header(“LOCATION:http://www.google.com“);
this will cause error.
Process 1 : Just Paste
error_reporting(0);
at the top of your page it will works fine.
if not work for you use
Process 2. :
paste
ob_start();
at the top of your page.
and paste
ob_end_flush();
at the bottom of your page
[ NB: process two is very usefull if you host your site into siteground ]

Great!!! Once I removed my all printf and print_r site is working smoothly
Muhammad Sajid said
Use ob_start() and ob_flush() to get rid of this problem. Actually this is a warning message and comes if the output buffer already contains any value it may be some garbage, so at the most top of the file use ob_start() and at the end of the file use ob_flush(). Yap no matter if the file contains session_start() at top.
For more detail please read http://www.php.net/manual/en/function.flush.php
