如何封装get 方法和post 方法（附代码）

引用了金老师代码，统一用g()方法来获取变量 function g($name, $defaultValue = "") {// php这里区分大小写，将两者都变为小写$_GET = array_change_key_case ( $_GET, CASE_LOWER );$name = strtolower ( $name );$v = isset ( $_GET [$name] ) ?              

function g($name, $defaultValue = "") {
	// php这里区分大小写，将两者都变为小写
	$_GET = array_change_key_case ( $_GET, CASE_LOWER );
	$name = strtolower ( $name );

	$v = isset ( $_GET [$name] ) ? $_GET [$name] : "";
	if ($v == "") 
        {
	    $_POST = array_change_key_case ( $_POST, CASE_LOWER );
	    $v = isset ( $_POST [$name] ) ?$_POST [$name] : "";
	}
            if ($v == "")
			return $defaultValue;
	    else
		{
			// 20141011 jc :  js_unescape($v)会引起 where ( col_subject like '%123%' ) 会变成 where ( col_subject like '%3%' )
			//$v =  js_unescape($v) ;
			$v = trim($v);
			return $v;
		}

	}

}
