What does these errors mean. does these errors have something to do with my hosting provider?

Answer 1

It looks as though you've probably copied your php.ini configuration file directly from your system to your hosting server. Don't do that. The data in your configuration file is specific to your XAMPP installation; this is not appropriate for the web server, and is causing these errors because the files referenced in your configuration do not exist on the server.

Answer 2

Sometimes people here are not as they could be...

For whatever reason, your php.ini is mis-configured.

One thing to note that all those missing files are actually Windows files (*.dll) on Linux these would likely be *.so files. I'm assuming your hosting on a Linux server.

First find your php.ini file. If you have command line access via SSH, you can try running:

php --ini

if not you make a simple script, call it test.php like so:

<?php
phpinfo();
?>

Upload the file and run it, something like:

http://www.yoursite.com/test.php

Among the information provided will be the path to php.ini

Once you find it, one option is to edit it and comment out all those extensions, by putting a ";" in front of the line.

Another option is to check if the *.so files exist. Look for them under /usr/lib/php. If they exist, edit your php.ini file to have all those extension end in .so instead of .dll

Finally, if they don't exist, you could install them by using apt-get or yum. An example:

sudo apt-get install php-mbstring

Answer 3

I had this error locally with this message:

Warning: Cannot open "\\xampp\\php\\extras\\browscap.ini" for reading in Unknown on line 0

By changing this line of php.ini file :

browscap="\xampp\php\extras\browscap.ini"

to this:

browscap="C:\xampp\php\extras\browscap.ini"

the error has gone.
