I have a server with this configuration:
centos 6.4
PHP 5.4
SQLite Library 3.6.20 (this is from phpinfo())
I desperately need to upgrade the sqlite library. I need to access from php a sqlite library. It seems that that database was created with sqlite 3.7. When I try to open it from php, I get this error "file is encrypted or is not a database". Updating that driver will solve the problem
Php was installed with the command yum --enablerepo=remi install php-fpm
I have found some answers like yum install php5-sqlite, it seems that this is an old command. Usually I find some outdated answers. I would need something to work with php 5.4. Installing with pecl did not work either.
Please help
I have no issue reading a sqliteDB generated with SQLite 3.8 (Fedora) from an CentOS 6 box with SQLite 3.6
php -r 'var_dump(
$db=new sqlite3("/tmp/test.sqlite"),
$q=$db->query("SELECT name FROM sqlite_master"));
foreach ($q->fetchArray() as $r) var_dump($r);'
With PDO:
php -r 'var_dump(
$db=new PDO("sqlite:/tmp/test.sqlite"),
$q=$db->query("SELECT * FROM sqlite_master"),
$q->fetchAll()); '
Of course, you need to use "sqlite3" or "pdo_sqlite" extension, not the old deprecated "sqlite" one.

In PHP I'm getting the following warning whenever I try to connect to a database (via mysql_connect)
Warning: mysql_connect(): Headers and client library minor version mismatch. Headers:50162 Library:50524
In my php -i output I have the following values listed under mysqli
Client API library version => 5.5.24
Client API header version => 5.1.62
I've tried updating php5-mysql and php but I'm already at the latest version of both of them. How do I go about updating the header version so I stop seeing this warning?
EDIT

I am using MariaDB and have a similar problem.
From MariaDB site, it is recommended to fix it by
Switch to using the mysqlnd driver in PHP (Recommended solution).
Recompile PHP with the MariaDB client libraries.
Use your original MySQL client library with the MariaDB.
My problem was fixed by using the mysqlnd driver in Ubuntu:
sudo apt-get install php5-mysqlnd
[update: extra information] Installing this driver also resolve PDO problem that returns integer value as a string. To keep the type as integer, after installing mysqlInd, do this
$db = new PDO('mysql:host='.$host.';dbname='.$db_name, $user, $pass,
array( PDO::ATTR_PERSISTENT => true));
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$db->setAttribute(PDO::ATTR_STRINGIFY_FETCHES, false);
For new MySQL 5.6 family you need to install php5-mysqlnd, not php5-mysql.
Remove this version of the mysql driver
sudo apt-get remove php5-mysql
And install this instead
sudo apt-get install php5-mysqlnd
Your PHP was compiled with MySQL 5.1 but now it is linking a mysql library of 5.5.X family.
You have to upgrade PHP to a version compiled with MySQL 5.5 or revert back mysql client libraries to 5.1.x.
The same works for MySQL:
sudo apt-get install php5-mysqlnd
I've read this thread trying to find the solution for MySQL, and I've also seen ken's answer, but I ignored the solution for MariaDB, wasting a few hours that way. It wasn't clear for me that the same may apply to MySQL. This post is just to spare you the few hours I lost.
The root reason for this error is that PHP separated itself from the MySQL Client libraries some time ago. So what's happening (mainly on older compiles of linux) is that people will compile PHP against a given build of the MySQL Client (meaning the version of MySQL installed is irrelevant) and not upgrade (in CentOS this package is listed as mysqlclientXX, where XX represents the package number). This also allows the package maintainer to support lower versions of MySQL. It's a messy way to do it, but it was the only way given how PHP and MySQL use different licensing.
MySQLND solves the problem by using PHP's own native driver (the ND), which no longer relies on MySQL Client. It's also compiled for the version of PHP you're using. This is a better solution all around, if for no other reason that MySQLND is made to have PHP talk to MySQL.
If you can't install MySQLND you can actually safely ignore this error for the most part. It's just more of an FYI notice than anything. It just sounds scary.
My hosting company told me to fix this by deactivating "mysqli" and activating "nd_mysqli" in the php extensions.
The error is gone, but I don't have the knowledge to understand if this is the right method to fix this.
To compile php from source with MySQL native driver (mysqlnd),
cd /php/source/path
./configure <other-options> --with-mysql --with-mysqli --with-pdo-mysql
make clean # required if there was a previous make, which could cause various errors during make
make
make install
From /php/source/path/configure --help.
--with-mysql=DIR Include MySQL support. DIR is the MySQL base
directory, if no DIR is passed or the value is
mysqlnd the MySQL native driver will be used
--with-mysqli=FILE Include MySQLi support. FILE is the path
to mysql_config. If no value or mysqlnd is passed
as FILE, the MySQL native driver will be used
--with-pdo-mysql=DIR PDO: MySQL support. DIR is the MySQL base directory
If no value or mysqlnd is passed as DIR, the
MySQL native driver will be used
One or more PHP MySQL extensions can be included by using these options.
If a value is not passed to these options, or if the value is mysqlnd, MySQL native driver will be used.

PHP Version 5.5.30
MySQL Version 10.0.26-MariaDB
For WHM and cPanel, some versions need to explicty set mysqli to build.
Using WHM, under CENTOS 6.9 xen pv [dc] v68.0.27, one needed to rebuild Apache/PHP by looking at all options and select mysqli to build. The default was to build the deprecated mysql. Now the depreciation messages are gone and one is ready for future MySQL upgrades.
I ran into the same issue on centos7. Removing php-mysql and installing php-mysqlnd fixed the problem. Thanks Carlos Buenosvinos Zamora for your suggestion.
Here are my commands on centos7 just in case this can be of help to anybody as most of the answers here are based on Debian/Ubuntu.
To find the installed php-mysql package
yum list installed | grep mysql
To remove the installed php-mysql package
yum remove php55w-mysql.x86_64
To install php-mysqlnd
yum install php-mysqlnd.x86_64
Works for MariaDB 10.6.4-MariaDB, php56w, on centos 7.7
yum remove php56w-mysqli
yum install php56w-mysqlnd
Changing PHP version from 5.6 to 5.5 Fixed it.
You have to go to control panel > CGI Script and change PHP version there.
I already have PHP 5.4 installed in a CentOS 7 VPS. I am trying now to access a legacy database in .mdb format with a PHP script.
However, my phpinfo() page says that only mysql and sqlite PDO drivers are enabled. No driver named ODBC is enabled.
Which is why I have tried to follow this tutorial to get that to work. But it doesn't work. bash: ./configure: No such file or directory.
I don't know from which folder I have to run the commands listed there. Is there a command which will allow me to install the PDO ODBC drivers from the system e.g. yum -y install php_odbc which would be easier for me to work with? If not, what am I doing wrong?
Looks like php_odbc is one of CentOS 7 packages.
See http://mirror.centos.org/centos/7/os/x86_64/Packages/ it is a very long list.
So yum -y install php_odbc should work. Just don't forget to restart your web-server if required.
You would run ./configure ... if you were compiling PHP from source. It will not work in your case.
I have already done much digging on installing/enabling PDO mysql extension on stackoverflow and many other sites, so please do not consider this as a duplicate question
I am on centos 6.5 and has php 5.5.26 which was compiled with make, make install (I know this is an older version so please do not close question or suggest updating to new php version. Also cannot install php using yum as this is what has been installed already me and should not be installed/changed).
So when I did compile php and added it to apache, it does not show mysql PDO driver. I tried putting extension=pdo_mysql.so to ini file with no success (yes I did restart the server as well, after making changes).
It shows pdo enabled, but only for drivers pgsql and sqlite.
Also, tried installing php-mysql package using yum. But the issue with yum installation is it installs 5.3.3 version of driver which complains about compatibility issues as my php version is 5.5.26.
So I am not sure what I need to do install pdo mysql extension
#Peter Darmis was right from his comments.
PHP 5.3.3 was not completely uninstalled, don't know why.
There was already a PHP installed manually be compilation and, as I wasn't aware about this, I was using yum for installation of modules and at that time PHP 5.3.3 got installed which I don't know why it dot un-install properly.
So I ended up with 2 PHP versions, so uninstalled PHP 5.3.3 completely using yum and then resolved this issue compiling PHP with pdo options
Today some of my packages in Ubuntu was upgraded automatically, and I didn't think of what was actually going on.
Ever since the update, my local dev-environment doesn't work anymore. First of by not working was mod_rewrite which I had to enable again using a2enmod. But now I've run into an issue that I can't seem to resolve. My application can't seem to find the PDO MySQL driver. When running the application, I get the error failed to open the DB connection: could not find driver.
This is strange, since if I check the phpinfo() the PDO drivers do support MySQL, and the socket path is a valid path.
pdo_mysql client API version is 5.5.35 according to php info.
PHP5: 5.5.3
MySQL: 5.5.35
Connectionstring
mysql:host=127.0.0.1;dbname=MyDB;port=3306
What could be causing this?
The PHP MySQL driver (mysql.so/mysqli.so) and the PHP PDO MySQL driver (pdo_mysql.so) are two separate modules. You need both of them for PDO functionality with MySQL.
It is quite possible that one of them is missing or of an incompatible version - I do not have an Ubuntu system at hand, but on my RPM-based Linux distribution there is a separate package for each module (php-mysql/php-mysqli and php-pdo_mysql). I also expect PDO to be using the newer mysqli.so driver, rather than the obsolete mysql.so one, so you should verify that one is installed as well.
Try this:
sudo apt-get install -y php5-mysql php5 mysql-client
This should automatically restart your apache if any of the dependencies aren't installed.
Try using vagrant.
Dependencies can be isolated, upgraded and downgraded when you like.
