LXI. mSQL functions


These functions allow you to access mSQL database servers. More information about mSQL can be found at



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/Hughes.

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)

Runtime Configuration

The behaviour of these functions is affected by settings in php.ini.

Table 1. mSQL configuration options

For further details and definition of the PHP_INI_* constants see ini_set().

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.

msql.max_links integer

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

Resource Types

Predefined Constants

The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.

MSQL_ASSOC (integer)

MSQL_NUM (integer)

MSQL_BOTH (integer)

To those porting code from w3-msql/lite to php, a few functions are different or missing (aside from the fact that the order of arguments is reversed and the other signatures are different...not good design work, imho, or was it built for msql 1.x?  At any rate, conformity with the C and Lite API should have been maintained.).
The lite/C function msqlStoreResult() is automatically done in msql_query() and msql(). 
<LI>msql_fetch_field() doesn't give you the field length value (unlike msqlFetchField()).  You have to call msql_fieldlen() to get that.
<LI>msqlEncode() is missing.  The functionality (which is needed for pretty much ALL SQL based rdbms's) is in addSlashes() in the String library.
