| Hi Jared,
this won't work, if you use a static class. I'm not shure, but in my =
opinion
all magic methods are usable in classes which can be instanciated.
Following snipped should work:
[snip]
if (!class_exists('TypeAssert')) {
class TypeAssert {
private static $types =3D array(
'array','bool','float','integer','null',
'numeric',
'object','resource','scalar','string'
);
public function __call($method,$arguments) {
$obj =3D $this->assertStandardTypes($arguments[0]);
return $obj->$method;
}
public function assertStandardTypes($para) {
$r =3D $this->getTypesObject();
if (is_array($para)) $r->array =3D true;
if (is_bool($para)) $r->bool =3D true;
if (is_float($para)) $r->float =3D true;
if (is_integer($para)) $r->integer =3D true;
if (is_null($para)) $r->null =3D true;
if (is_numeric($para)) $r->numeric =3D true;
if (is_object($para)) $r->object =3D true;
if (is_resource($para)) $r->resource =3D true;
if (is_scalar($para)) $r->scalar =3D true;
if (is_string($para)) $r->string =3D true;
return $r;
}
public function getTypesObject() {
$obj =3D (object) '';
for ($i =3D 0; $i < count(self::$types); $i++) {
$obj->{self::$types[$i]} =3D (bool) false;
}
return $obj;
}
}
}
$TypeAssert =3D new TypeAssert();
echo('<pre>');
echo($TypeAssert->string('test'));
echo('</pre>');
[/snap]
