Posted this on the function-handling function page, but it seems it's a topic here too. I've developed an easy-to-use hack using these functions to emulate overloaded functions. It's especially handy for constructors and/or C++ style templating. Here's a little example to get you going. This does the trick for most circumstances, and if you need more intelligent parsing, it's not too hard to implement with regex or a more suitable classification scheme. N.B. Note the lack of whitespace between variable types in case strings. class Matrix { ... function Matrix() { $args = func_get_args(); $argmatch = implode(",", array_map('gettype', $args)); switch( $argmatch ) { case 'integer,integer': //initialize m x n matrix break; case 'integer,integer,integer': //initialize m x n matrix with constant c break; case 'integer,integer,float': //initialize m x n matrix with constant c break; case 'array': //initialize from array (2D....) break; case 'array,integer': //intialize from array (1D packed with m rows) break; default: //(void) overload? //error handling? break; } } ... } ---- Manual Page -- http://www.php.net/manual/en/langref.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+50239 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+50239&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+50239&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+50239&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+50239&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+50239&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+50239&report=yes Search -- http://master.php.net/manage/user-notes.php
