There is a patch to allow this IIRC but has not been merged into,and probably will only be included with PHP6. ------------------------------------------------------------------------ [2007-03-12 06:04:45] tims at arizona dot edu Description: ------------ I have found a minimal reproducible test case that consistently fails. I believe this should work as a typed parameter but php5 dies with the result below. Reproduce code: --------------- $b = true; function f( boolean $a ) { return $a; } f( $b ); Expected result: ---------------- The above code does not do much except return the boolean that was passed in. My larger block of code uses typed arguments to ensure the type of data being passed in. The bool type does not work and I can not find a suitable workaround. Actual result: -------------- Catchable fatal error: Argument 1 passed to f() must be an instance of boolean, boolean given, called in /home/bink/Projects/opticsnow/web_software/dev_space/a.php on line 5 and defined in /home/bink/Projects/opticsnow/web_software/dev_space/a.php on line 4 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40782&edit=1
