[PHP] Re: PHP5 Static functions called through __call() that don't exist... yet
Hi,
I also think this a good proposal, but you might consider writing to the
internals group, as this group is only for discussions and most of the
people that read it are PHP users and have no idea how the language is made
(including me).

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 = $v) {
echo(divis_b style=\color: #00a;\$type/b(b$_test/b) === .
(TypeAssert::$assert-$type($test)?
'b style=color: #0a0;true/b':
'b style=color: #a00;false/b').
/div\n
);
}
echo(/pre\n);

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-generalm=114558851102060w=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?
Thanks!

Hi Jared,
I think you meant to post to php-general, but I can answer your question.
***PLEASE DO NOT REPLY TO PEAR-GENERAL THANK YOU***
You can achieve what you want through this kind of code
?php
class TypeChecker
{
private static $types = array(
'array','bool','float','integer','null','numeric',
'object','resource','scalar','string'
);
public static $singleton;
static function init()
{
self::$singleton = new TypeChecker;
}
function __call($method, $args)
{
$test = new StdClass;
foreach (self::$types as $thing) {
$test-$thing = ${is$thing}($args[0]);
}
return $test-$method;
}
}
TypeChecker::init()
echo TypeChecker::$singleton-string('test');
?
However, I don't see any benefit to using static methods here. Just use
an object.
?php
class TypeChecker
{
private $types = array(
'array','bool','float','integer','null','numeric',
'object','resource','scalar','string'
);
function __call($method, $args)
{
$test = new StdClass;
foreach (self::$types as $thing) {
$test-$thing = ${is$thing}($args[0]);
}
return $test-$method;
}
}
$check = new TypeChecker;
echo $check-string('test');
?
If you're trying to do several assertions and separate them into
classes, do something like so:
?php
class Tester
{
public $type;
...
function __construct()
{
$this-type = new TypeChecker;
}
}
$check = new Tester;
echo $check-type-string('test');
?
