我对 MySQL 中的行数感到困惑。phpMyAdmin 和 count 查询返回的总行数不同。
我的表结构是InnoDB.
Showing rows 0 - 24 (655537 total, Query took 0.1527 seconds.)

这是浏览表格时的结果。
我的计数查询是
SELECT count(*) FROM `table_name`

这将返回为602030
我试图添加任意类型的嵌套数组。这些是我的注释:
* @OA\Property(
* @OA\Schema(
* type="array",
* @OA\Items(
* type="array",
* @OA\Items(type={})
* )
* ),
* description="bla bla bla"

这是我的查询,但它不起作用

换句话说,我需要当我按下"Continua->"按钮时,我将被重定向到HREF页面,但是在链接的末尾添加了"idCantiere"
我正在尝试构建HTML而不必重复代码.基本上我可以选择打印或保存到文件; 选项将通过$_GET.
我遍历一个csv,所以HTML接收了很多变量.
我想过有一个变量$ action;
If $action == 'view' then
echo "<h1>Hello World</h1>";
If $action == 'save' then
file_put_contents($file,"<h1>Hello World</h1>", FILE_APPEND);
Run Code Online (Sandbox Code Playgroud)
我不喜欢不得不重复代码的想法,一个部分使用echo而另一部分file_put_contents.
我知道这是完全错误的,只是试图提出这个想法,有没有一种方式设置这样的变量?
if ($action == "view") {$start = 'echo'; $end = ';';}
elseif ($action == "save") {$start = 'file_put_contents($file,'; $end = ', FILE_APPEND);';}
$start "<h1>Hello World</h1>" $end
