''//'' in url

[zhq]

Hi all,

I am using iis 6.0, php 4.4.1 and mysql 4.1.18. I have the problem - the url becomes like http://localhost//... once the page is connected to mysql database. Can anyone tell what the reason could be?

Any help will be much appreciated.

Can you give more detail?  Where do you see that url?  And what is in your php script?

In IE address field, something like http://localhost//faqdisplay.php?page=59&type=2. The script is working fine under Xitami Web server. The faqdisplay.php script is below.

I suspect $filedir is not set correctly, probably because $HTTP_SERVER_VARS have different values in the different webserver.

Try looking at the output from this:

[code=php:0]echo "<pre>"; var_dump($HTTP_SERVER_VARS);[/code]


That will show you what is available in $HTTP_SERVER_VARS

You can also try

[code=php:0]echo "<pre>"; var_dump($_SERVER);[/code]


$_SERVER is the new name for $HTTP_SERVER_VARS.

Hi,

I found that it is because of **dirname($HTTP_SERVER_VARS['PHP_SELF']) ** which returns a '/' or '\' in new php version. Can any code replace the slash with an empty string.

regards

[Daniel0]

[code]$string = str_replace('/','',$string);[/code] will replace a slash with "nothing".

Hi,

I got a ' Parse error: parse error, unexpected T_ELSEIF in c:\inetpub\wwwroot\vlsi\forward.php on line 8' message after I changed the first few lines in order to ensure that dirname($HTTP_SERVER_VARS['PHP_SELF']) is not equal to "/" and "\".
