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");
?>

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?
Thanks!
