소개
These functions allow you to access mSQL database servers. More
information about mSQL can be found at
http://www.hughes.com.au/.
설치
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)

예제
This simple example shows how to connect, execute a query, print
resulting rows and disconnect from a mSQL database.
예 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') or die('Could not select database', $link);
/* 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); ?>
