PHP批最取得checkbox的值

1、命名


2、使用

当计划当作sql指令的一部分时:如果参与控制的字段是数值型的,则

if(! empty($_POST['checkbox'])) {
$expr = join(",", $_POST['checkbox']);
$sql = "select * from tbl_name where field in ($expr)";
}
如果参与控制的字段是数值型的,则

if(! empty($_POST['checkbox'])) {
$expr = "'".join("','", $_POST['checkbox']).".";
$sql = "select * from tbl_name where field in ($expr)";
}

PHP判断Form表单是否提交

$action=$HTTP_POST_VARS["Button1"];
if($action=="提交")
{
//执行表单操作
}
else
{
//读取默认值
}

PHP 获取字符串长度

strlen($myrow[1])

PHP Url转向

Header("Location: ".$_SERVER["HTTP_REFERER"]);

PHP超全局对象

$a = 1;
$b = 2;
function Sum()
{
$GLOBALS["b"] = $GLOBALS["a"] + $GLOBALS["b"];
}
Sum();
echo $b;
?>

PHP 表单取值

如果 mothod="get" 就用 $_GET["test"] 代替$test
如果 mothod="post" 就用 $_POST["test"] 代替$test

PHP取得当前IP

=$HTTP_SERVER_VARS["REMOTE_ADDR"]?>

PHP 取得当前时间

echo date("Y-m-d G:i:s");
?>
date("Y年m月d日")
Date ("Y-n-j")
