mSQL Functions

Introductie

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

Installatie

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

Configuratie tijdens scriptuitvoer

Het gedrag van deze functies wordt beïnvloed vanuit php.ini.

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 php.ini directives.

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.

The maximum number of mSQL connections per process, including persistent connections.

Resource types

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.

Voorgedefinieerde constanten

Deze constanten worden gedefinieerd door deze extensie, en zullen alleen beschikbaar zijn als de extensie met PHP is meegecompileerd, of als deze dynamisch is geladen vanuit een script.

MSQL_ASSOC (integer)
MSQL_NUM (integer)
MSQL_BOTH (integer)

Voorbeelden

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 (
$row msql_fetch_array($resultMSQL_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);
?>
