These functions allow you to access mSQL database servers. More information about mSQL can be found at http://www.hughes.com.au/.
In order to have these functions available, you must compile PHP with msql support by using the --with-msql[=DIR] option. DIR is the mSQL base install directory, defaults to /usr/local/msql3.
Note to Win32 Users: In order to enable this module on a Windows environment, you must copy msql.dll from the DLL folder of the PHP/Win32 binary package to the SYSTEM32 folder of your windows machine. (Ex: C:\WINNT\SYSTEM32 or C:\WINDOWS\SYSTEM32)
The behaviour of these functions is affected by settings in php.ini.
Table 1. mSQL configuration options
Name | Default | Changeable | Changelog |
---|---|---|---|
msql.allow_persistent | "1" | PHP_INI_ALL | |
msql.max_persistent | "-1" | PHP_INI_ALL | |
msql.max_links | "-1" | PHP_INI_ALL |
Here's a short explanation of the configuration directives.
There are two resource types used in the mSQL module. The first one is the link identifier for a database connection, the second a resource which holds the result of a query.
The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
This simple example shows how to connect, execute a query, print resulting rows and disconnect from a mSQL database.
