Hello i have formatted my pc with Windows 7 and installed wamp server. My local project doesnt work.
I am familiar with the difference between mysql and mysqli? Do i need to install a most recent version of Mysql than the one provided by Wamp Server?

You should always make a habit of keeping up with newer versions, mainly because these versions are released for a reasib (security patches, bugs etc.)

I think PHP v5.3+ should cover it, but we are currently on v5.6, so you really should've upgraded a long time ago. MySQLi is a component of PHP, not the MySQL database engine, so it shouldn't matter which version you have. Again, I do reccomend v5.6 ish for efficiency/security reasons.

if you already have php installed you most likely just need to enable mysql in your php.ini file

Personally I would use XAMPP, as the binaries are that much more complicated to get sorted. As well as building and actually installing PHP, getting it to communicate with Apache and MySQL can be an absolute nightmare.

But as @jstfsklh211 correctly says, do check your ini file first. These will be the settings to look for.

The php.ini is just the PHP config file, and will definitely be present in all versions of PHP. In your root PHP directory (where all of the PHP system/core files are stored - i.e. C:\wamp\bin\php\ or C:\wamp\bin\php\php5.5.12 for example) there will be a file called php.ini, and in that massive file will be those settings.

Updating PHP can be onerous as pointed out by mattster. I also use XAMPP, so not familiar with WAMP. But, installing PHP binary over a previous XAMPP install went spectacularly badly for me, so I just install new versions of XAMPP, as and when they're considered stable. I back up all data (php.ini, DB and sites first). Make sure that you check any installed libraries for upadtes too - some third party libraries you may have installed and using may be PHP version dependent.

The first thing to check in your php.ini file is this


if you have this line in your file uncomment it by removing the semicolon then restart your webserver this tells apache to load support for mysqli

WHat does phpinfo() give you?

[02-Jul-2015 13:34:41 UTC] PHP Warning: PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.5.12/ext/php_intl.dll' - The specified module could not be found.

I've done them all

; Windows Extensions
; Note that ODBC support is built in, so no dll is needed for it.
; Note that many DLL files are located in the extensions/ (PHP 4) ext/ (PHP 5)
; extension folders as well as the separate PECL DLL download (PHP 5).
; Be sure to appropriately set the extension_dir directive.

extension=php_exif.dll      ; Must be after mbstring as it depends on it
extension=php_oci8.dll      ; Use with Oracle 10gR2 Instant Client
extension=php_oci8_11g.dll  ; Use with Oracle 11gR2 Instant Client

Is the php.ini file you have from a previous install?

Otherwise, can't see why a downloaded version would have these refs in php.ini uncommented if they weren't included in that release.

So is that file missing too?!

I have installed twice wamp in the first place. Plus there was a file on the php folder -the one that enables the extensions- called php.ini.development and opened it with notepad and now its called just php. Oh and another thing. Should i implement the php-5.6.10 version i downladed ?

I thing that something goes bad. My website has a login page. On the login page i can't retreive data from my database but on the index page the data are shown

WTF? You're babbling.

php.ini.development is probably the file you want as it's a dev machine not a production server right?

Rename this to php.ini. Check there's not another file with this name already. If there is, check that that file isn't a hangover from a previous version.

If you keep running into problems and are spending days over this, maybe backup all your data (dbs and sites) and bite the bullet by deleting wamp and re-installing it. You can then copy over your saved dbs and sites.

With regard to your site - who knows? You give absolutely no info with regard to the content, file structure etc. This is starting to turn into a crystal ball gazing affair.
