LXXIX. mSQL Functions

Введение

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

Установка

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)

Настройка во время выполнения

-Поведение этих функций зависит от установок в php.ini.

Краткое разъяснение конфигурационных

директив.

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.

Типы ресурсов

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.

Предопределенные константы

-Перечисленные ниже константы определены данным расширением и могут быть

доступны только в том случае, если PHP был собран с

поддержкой этого расширения или же в том случае, если

данное расширение подгружается во время выполнения.

MSQL_ASSOC (integer)

MSQL_NUM (integer)

MSQL_BOTH (integer)

Примеры

This simple example shows how to connect, execute a query, print resulting rows and disconnect from a mSQL database.

Пример 1. mSQL usage example

<?

/*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);

?>
