OK, that changes everything - I was thinking like C++ classes, which, if my memory serves me correctly, know which member function to use. Modified code that deals with this OK: ======================================================== #!/usr/bin/php -q <?php error_reporting (E_ALL); class test { var $currentField; function setCurrentField($field_name) { $this->currentField = $field_name; } function getValue($field_name = false) { if ($field_name === false) $field_name = $this->currentField; return "getValue with arg - $field_name\n"; } } $frm = new test; $frm->setCurrentField("blah"); print $frm->getValue("real arg"); print $frm->getValue(); ?> ======================================================== > That's an ZE problem (ie. > method with same name should give parse error or at least some > warning). Agreed. Testing this with straight functions shows that the engine does do this for straight functions: ======================================================== #!/usr/bin/php -q <?php error_reporting (E_ALL); function blah() { print "no arg\n"; } function blah($field) { print "with arg, $field\n"; } blah(); blah("test"); ?> ======================================================== Output gives: [root tmp]# ./test.php <br> <b>Fatal error</b>: Cannot redeclare blah() in <b>./test.php</b> on line <b>9</b><br> [root tmp]# An equivalent "Cannot redeclare test class member function blah() in test.php on line 9" would be extremely helpful and is probably called for - I've always found the PHP syntax checking to extremely clear and spot-on previously. Many thanks for all your help, Kind Regards, Nick. ------------------------------------------------------------------------ [2001-11-26 03:05:16] mfischer@php.net Your code is obviously bogus. You're definig two methods with the same name. But I admit this shouldn't be possible, derick? Anyway, because of this the second getValue() overwrites the former and therefore you have an infinite look; getValue calls getValue calls getValue calls ... That's an ZE problem (ie. method with same name should give parse error or at least some warning). (Correct if otherwise) ps: php doesn't call funtions based on the parameters given ------------------------------------------------------------------------ [2001-11-26 02:46:22] derick@php.net Can you try the latest RC from : www.php.net/~zeev/php-4.1.0RC3.tar.gz ?
