#39466 [Bgs->Opn]: Expaned Class constants to accept return of function value

ID: 39466 User updated by: kevin at metalaxe dot com Reported By: kevin at metalaxe dot com -Status: Bogus +Status: Open Bug Type: Feature/Change Request Operating System: * PHP Version: 5.2.0 New Comment: Ok, if that is the case, how does the global constant MAGIC_QUOTES get defined from the code in the description? <?php define( 'MAGIC_QUOTES', ( (bool)get_magic_quotes_gpc() ), true ); var_dump( MAGIC_QUOTES ); ?> prints bool(true) We are running 3 functions there (according to the docs). One to get the value being applied, another to cast to int and finally one to "define" the constant. Previous Comments: ------------------------------------------------------------------------ [2006-11-10 22:26:50] tony2001@php.net That's not possible, as constants are declared at compile time, while functions are executed at runtime. ------------------------------------------------------------------------ [2006-11-10 22:11:17] kevin at metalaxe dot com Description: ------------ You can define a global constant based on the return of a function yet you cannot do so for class constants. eg. define( 'MAGIC_QUOTES', ( (bool)get_magic_quotes_gpc() ), true ); Requesting a method to assign class constants in a manner similar to global constants Reproduce code: --------------- <?php class parser { const magic_quotes = (bool)get_magic_quotes_gpc(); public my_stripslashes( $str ) { if( self::magic_quotes === true ) { $str = stripslashes( $str ); } return $str; } } ?> Expected result: ---------------- Constant "magic_quotes" to be assigned the boolean value of get_magic_quotes_gpc's return. Actual result: -------------- With boolean cast: Parse error: syntax error, unexpected T_BOOL_CAST in parser.php on line 4 Without boolean cast: Parse error: syntax error, unexpected '(', expecting ',' or ';' in parser.php on line 4 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39466&edit=1
