Perfect! Thanks!
Thanks Bob,
I recently moved to a VPS server after years of shared hosting and spent weeks trying to learn and install various things using the SHELL access. Today after following the steps in your tutorial to install POD, I realised I could have used this exact same method for the Zend Optimizer and Ioncube loader etc. Feeling really silly now. Many Thanks, Toria
this has had me up all night hope it works
Thanks!
Hello, I want to ask If there is any possibillity to lose me data of server If i make the update. Thanks
if you’re referring to the database you won’t lose any data. What it actually does it just re-compile your php build base on the your old setting plus additional module you want to install.
thanks Bob!
Thanks for breaking it down Bob. A lot simpler than any other tut’s I could find
Hello, I want to ask something about if the re-compile doesn’t work.. do we have a Second Plan?
Thanks
You can install it manually by doing this.
1. $ pecl install pdo
now add the extension in php.ini file
; Extension PDO
extension=pdo.so
Hope this would help.
Thank you so much for help me out
PDO is working
