Re: PHP5 Static functions called through __call() that don't exist... yet

Hi all, Here is more code, with a test case included. What I would prefer to do is call TypeAssist::$string(), instead of TypeAssist::$a->string(). Or at least __construct() the $a object. <code> <?php if (!class_exists('TypeAssert')) { class TypeAssert {

       public static $a;
       public static $assert;
       private static $types = array(
           'array','bool','float','integer','null','numeric',
           'object','resource','scalar','string'
       );
       function __construct() {
           self::$assert =& self::$a;
       }
       public static function __call($method,$arguments) {
           $obj = self::assertStandardTypes($arguments[0]);
           return $obj->$method;
       }
       public static function assertStandardTypes($para) {
           $r = TypeAssert::getTypesObject();
           foreach ($r as $type=>$v) {
               $func = "is_".strtolower($type);
               if (function_exists($func) === true) {
                   if ($func($para) === true) {
                       $r->$type = true;
                   } else {
                       $r->$type = false;
                   }
               }
           }
           return $r;
       }
       public static function getTypesObject() {
           $obj = (object) '';
           for ($i = 0; $i < count(self::$types); $i++) {
               $obj->{self::$types[$i]} = (bool) false;
           }
           return $obj;
       }

} } TypeAssert::$a = new TypeAssert(); echo("<pre>\n"); switch($_GET['type']) { case 'int':

       $test = 100;
       $_test = 100;

break; case 'float':

       $test = 100.001;
       $_test = 100.001;

break; case 'null':

       $test = null;
       $_test = 'null';

break; case 'object':

       $test = TypeAssert::$a;
       $_test = '[object]';

break; default:

       $test = 'string';
       $_test = 'string';

break; } foreach (TypeAssert::getTypesObject() as $type => $v) { echo("<div>is_<b style=\"color: #00a;\">$type</b>(<b>$_test</b>) === ".

             (TypeAssert::$assert->$type($test)?
                  '<b style="color: #0a0;">true</b>':
                      '<b style="color: #a00;">false</b>').
                          "</div>\n"

); } echo("</pre>\n"); ?> </code> Original Message Text

Hi all, I am building an assertType object using static functions. What I want to keep away from is the following: <code> public static function assertString($para){

    return $answer;

}; public static function assertBool($para){

    return $answer;

}; ... public static function assertArray($para){

    return $answer;

}; </code> What I would like to do is replace this with the following: <code> if (!class_exists('TypeAssert')) {

    class TypeAssert {
        private static $types = array(
            'array','bool','float','integer','null','numeric',
            'object','resource','scalar','string'
        );
        public static function __call($method,$arguments) {
            $obj = self::assertStandardTypes($arguments[0]);
            return $obj->$method;
        }
        public static function assertStandardTypes($para) {
            $r = TypeAssert::getTypesObject();
            if (is_array($para))    $r->array = true;
            if (is_bool($para))     $r->bool = true;
            if (is_float($para))    $r->float = true;
            if (is_integer($para))  $r->integer = true;
            if (is_null($para))     $r->null = true;
            if (is_numeric($para))  $r->numeric = true;
            if (is_object($para))   $r->object = true;
            if (is_resource($para)) $r->resource = true;
            if (is_scalar($para))   $r->scalar = true;
            if (is_string($para))   $r->string = true;
            return $r;
        }
        public static function getTypesObject() {
            $obj = (object) '';
            for ($i = 0; $i < count(self::$types); $i++) {
                $obj->{self::$types[$i]} = (bool) false;
            }
            return $obj;
        }
    }

} echo('<pre>'); echo(TypeAssert::string('test')); echo('</pre>'); </code> I don't think this is possible (see http://marc.info/?l=php-general&m=114558851102060&w=2 ). But I would LIKE for it to work (currently, the above code doesn't). Anybody have any insight on how I might get this to work?
