PHP v4.3.1 Problems

[4x4uk]

My webserver has just been upgraded with PHP4.3.1
now in a few of my scripts where I have used

header("location:

http://www.mysite.com/file.php");

I get the following errors

Warning: Cannot modify header information - headers already sent by (output started at /mnt/mss-1/vol4/web/n/ne/ne4/

http://www.ne4x4.org.uk/web/test/hdr.inc:3)

in /mnt/mss-1/vol4/web/n/ne/ne4/

http://www.ne4x4.org.uk/web/test/e-link.php

on line 19

anyone any ideas what is causing the problem as everything worked fine with the previous version of php
Thanks
Ian

ne4x4,

All this means is that something was sent in line 19 of the script indicated.
This could be due to different error reporting settings in your PHP installation.
The

header()

command has to be the first thing sent to the browser in order to redirect.

Check line 19 in the offending script and see what's being output.
You can also use output buffering to catch all the output before the header command if you can't get rid of the offending output - which is the better choice anyway.

Many thanks for the response, I will look at the two scripts and should be able to resolve the problem. I fixed most of the other ones which occured since the upgrade some were silly mistakes like
$_POST[varname] which worked with version 4.2 changed to
$_POST['varname'] for version 4.3
I will probably contact the webhost also as I don't seem to be able to get
session_start() to work anymore and this simple count sript no longer works

case &quot;gfx&quot;:
$i = 0;
$cntn = strlen($num);

$tmpnum = substr($num, $i, 1);

Where did you get the variable $type assign?
The codes are not complete.
I can't make a guess.
Did you turn on the register_global?
A lot of times the header error comes because you print something before the session_start().
Sorry can't help much.

Hi mikefn

sorry about the missing variables I somehow managed to delete them form the post. They are were at the top of the script.
$type = &quot;gfx&quot;;
$dir = &quot;Gifs&quot;;

The reason the above script stopped working appears to be the following line

exec(&quot;echo $num > count.txt&quot;

I replaced the above line with

$fd = @fopen(&quot;count.txt&quot;,&quot;r+&quot;
fputs($fd,&quot;$num&quot;
fclose($fd);


Fixed all but a couple of minor problems now.
Many thanks
regards
Ian
