mSQL Functions

הקדמה

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

התקנה

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

    or die(
'Could not select database');

/* Issue SQL query */
$query 'SELECT * FROM my_table';

/* Printing results in HTML */
echo "<table>\n";
while (
$row msql_fetch_array($resultMSQL_ASSOC)) {

        echo 
"\t\t<td>$col_value</td>\n";
    }
