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 | |
For further details and definitions of the
PHP_INI_* constants, see the
Appendix G.
Here's a short explanation of
the configuration directives.
- msql.allow_persistent
boolean
Whether to allow persistent mSQL connections.
- msql.max_persistent
integer
The maximum number of persistent mSQL connections per process.
- msql.max_links
integer
The maximum number of mSQL connections per process, including
persistent connections.
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.
Example 1. mSQL usage example
<?php
/* Connecting, selecting database */
$link = msql_connect('localhost', 'username', 'password')
or die('Could not connect : ' . msql_error($link));
msql_select_db('database', $link)
or die('Could not select database');
/* Issue SQL query */
$query = 'SELECT * FROM my_table';
$result = msql_query($query, $link) or die('Query failed : ' . msql_error($link));
/* Printing results in HTML */
echo "<table>\n";
while ($row = msql_fetch_array($result, MSQL_ASSOC)) {
echo "\t<tr>\n";
foreach ($row as $col_value) {
echo "\t\t<td>$col_value</td>\n";
}
echo "\t</tr>\n";
}
echo "</table>\n";
/* Free result set */
msql_free_result($result);
/* Close connection */
msql_close($link);
?>
