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: Note to Win32 Users In order for this extension to work, there are DLL files that must be available to the Windows system PATH. See the FAQ titled "How do I add my PHP directory to the PATH on Windows" for information on how to do this. Although copying DLL files from the PHP folder into the Windows system directory also works (because the system directory is by default in the systems PATH), it is not recommended. This extension requires the following files to be in the PATH: msql.dll
php.ini中的設定會影響這些函數的行為。
Name | Default | Changeable | Changelog |

這裡為簡短的結構指令說明。
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.
以下的常數由此延伸定義,只在這個延伸被編譯成PHP或實行時期被動態載入時有效。
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, $link) or die('Query failed : ' . msql_error());
/* Printing results in HTML */
echo "<table>\n";
while ($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);
?>
