msession_unlockXCV. mSQL Functions
简介
These functions allow you to access mSQL database servers. More information about mSQL can be found at » http://www.hughes.com.au/.
安装
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 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
运行时配置
这些函数的行为受 php.ini 的影响。
表158.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 |
有关 PHP_INI_* 常量进一步的细节与定义参见附录H, php.ini 配置选项。
以下是配置选项的简要解释。
资源类型
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.
预定义常量
以下常量由本扩展模块定义，因此只有在本扩展模块被编译到 PHP 中，或者在运行时被动态加载后才有效。
范例
This simple example shows how to connect, execute a query, print resulting rows and disconnect from a mSQL database.
例1284.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);
?>
