この PHP 5.3 で導入された匿名関数を、以前のバージョンの PHP で動作するように変換するのに苦労しています。
私が得ているエラーは次のとおりです。予期しない T_FUNCTION と $testResult に関するものです。これが無名関数です。誰でもこれを変換して、以前のバージョンの PHP で動作するようにできますか? コードはクラス内にあります。
コードは次のとおりです。
abstract class geocoder {
public $ch = null;
public $xd = null;
public $xp = null;
public function __construct() {
$this->ch = curl_init();

foreach ($res['results'][0]['address_components'] as &$v)
foreach ($map as $k => &$l)
if (in_array($l, $v['types']) && !isset($comp[$k]))
$comp[$k] = $v['long_name'];
}
return array ('formatted' => (isset($res['results'][0]['formatted_address']) ? $res['results'][0]['formatted_address'] : NULL),
'components' => &$comp,

}
PHP 5.2でこれを機能させるのを手伝ってくれる人はいますか?
