LXIV. MySQL Functions
Introduction
These functions allow you to access MySQL database servers.
More information about MySQL can be found at http://www.mysql.com/.
Documentation for MySQL can be found at http://www.mysql.com/documentation/.
Requirements
In order to have these functions available, you must compile
PHP with MySQL support.
Installation
By using the --with-mysql[=DIR] configuration option you
enable PHP to access MySQL databases.
In PHP 4, the option --with-mysql is enabled by default.
To disable this default behavior, you may use the --without-mysql
configure option. Also in PHP 4, if you enable MySQL without
specifying the path to the MySQL install DIR, PHP will use
the bundled MySQL client libraries. In Windows, there is
no DLL, it's simply built into PHP 4. Users who run other
applications that use MySQL (for example, auth-mysql) should
not use the bundled library, but rather specify the path
to MySQL's install directory, like so: --with-mysql=/path/to/mysql.
This will force PHP to use the client libraries installed
by MySQL, thus avoiding any conflicts.
In PHP 5, MySQL is no longer enabled by default, nor is
the MySQL library bundled with PHP. Read this FAQ for details
on why.
This MySQL extension doesn't support full functionality
of MySQL versions greater than 4.1.0. For that, use MySQLi.
If you would like to install the mysql extension along
with the mysqli extension you have to use the same client
library to avoid any conflicts.
Warning
Crashes and startup problems of PHP may be encountered when
loading this extension in conjunction with the recode extension.
See the recode extension for more information.
Note: If you need charsets other than latin (default),
you have to install external (not bundled) libmysql with
compiled charset support.
