PHP upload: Files are assigned to nobody

admin — Tue, 11 May 2010 10:09:18 +0000

PHP uploaded files will generally get uploaded with the user nobody when using mod_php. This is the apache module for PHP which means the file will be uploaded with the apache user. In order to work around this you can modify your code to chown the file to the appropriate ftp user. The best option is to use PHP in FCGI mode or install SuPHP. This will ensure the files will always upload using the folder owner id.

Using cpanel this can be installed using the easyapache tool.

Plesk Billing – internal error has occurred- license

admin — Wed, 07 Apr 2010 16:49:42 +0000

Error:
When trying to activate the plesk billing license you receive a internal error message: ok , so what does this mean.. if you ask plesk , you will need to wait 72 hours for a answer. so this is why we have openkb.org

Reason: check and make sure fopen is on in the php.ini file and openssl has been compiled with php.

other error you may receive
You must have the OpenSSL extension enabled in your PHP installation in order to use Parallels Plesk Billing. You do not.
Invalid license data found in system. You need to update your license to a Parallels Plesk Billing 6.x license key. Please contact support for help with this process.

PHP 5.3 – Date warning

admin — Wed, 17 Mar 2010 17:37:32 +0000

Wow, PHP is changing the way we code our websites

More Warnings
Warning: date() [function.date]: It is not safe to rely on the system’s timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected ‘America/New_York’ for ‘EDT/-4.0/DST’ instead in

Solution :
date.timezone will need to be set within the php.ini file as
date.timezone = “timezone”
Supported timezones
America/New_York

Also Set the function date_default_timezone_set
Example date_default_timezone_set(‘America/Los_Angeles’);

possible errors:
Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown error.

PHP/IIS7 – IIS to return a 502 Bad Gateway

admin — Sun, 17 Jan 2010 00:19:43 +0000

php-cgi.exe does work on IIS7. You need to modify PHP.INI to have the line:

cgi.force_redirect = 0

If you do not do this modification, PHP-CGI.EXE outputs a security warning response without proper response headers, which causes IIS to return a 502 Bad Gateway. Strangely, running PHP-CGI.EXE from the commandline does not generate this error – I guess using NPH CGI is the only way to debug PHP, because running it from the commandline is not 100% indicative of web-server Runtime behavior.

PHP compression using gzip

admin — Sun, 10 Jan 2010 18:46:16 +0000

The best way to compress PHP files is to use

auto_prepend_file

Add the filling code to a file called gzip.php

if (substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip'))


        ob_start("ob_gzhandler");
    else
        ob_start();

?>
Then update your php.ini files as follows

auto_prepend_file= /path/to/gzip.php

you can also use a htaccess file if your server permits

php_value auto_prepend_file gzip.php

Testing the compression
or
curl -I -H ‘Accept-Encoding: gzip,deflate’ http://www.example.com

PHP – File too large to upload

Your file size upload is controlled by two variables in php.ini

upload_max_file_size and post_max_file_size

missing the mysql which is required for wordpress

admin — Sat, 12 Sep 2009 00:50:35 +0000

php installation appears to be missing the mysql which is required for wordpress

======
open the php.ini file.
if you do a search for extension=php_mysql.dll and un comment it ie delete the ; at the beginning of the line
then search further up in the ini file for extension_dir=”./” and replace ./ with c:\php\ext (assuming your php is in c:\php) so it will look like: extension_dir=”c:\php\ext”. This tells php that the dllfor the php_mysql.dll is located in c:\php\ext.
save your php.ini
Also copy libmysql.dll from c:\php c:\windows\system32 and then restart IIS
