I developed a website with PHP version 5.1.4 and MySQL - 5.0.22. I tested the web on my localhost and it worked perfectly well. However, when I uploaded the website, I could not have access to all have to all the data inserted in my database. I could not understand the reason for this. However, after complaining to the hosting company, it was suggested that probably there is a difference in the php.ini of my localhost and that of the hosting company. The php.ini of the web hosting company is Debian, MySQL Version: 5.0.91, Perl Version: 5.8.8. Being a newbie in this, is it possible that the difference in this developmental portal and the hosting portal could lead to my inability to access of my data in the database of the hosting company?
