If you need to load an extension from the CURRENT local directory because you do not have privelages to place the extension in your servers PHP extensions directory, this function i wrote may be of use to you <?php /* Function: dl_local() Reference: http://us2.php.net/manual/en/function.dl.php Author: Brendon Crawford <endofyourself |AT| yahoo> Usage: dl_local( "mylib.so" ); Returns: Extension Name (NOT the extension filename however) NOTE: This function can be used when you need to load a PHP extension (module,shared object,etc..), but you do not have sufficient privelages to place the extension in the proper directory where it can be loaded. This function will load the extension from the CURRENT WORKING DIRECTORY only. If you need to see which functions are available within a certain extension, use "get_extension_funcs()".
