Question

我正在尝试更改a中字段的值。多维数组。请注意，我不是PHP大师，我还在学习。

我使用以下结构

array(
      array(ID+value, GRANTED+value)
)

我使用以下代码：

// accept in session
foreach ($_SESSION['chatrequests'] as $request) {
    error_log("accepting chat request with id " . $request['ID'] . "  and the incoming  request is " . $requestid);
    if ($request['ID'] == $requestid) {
        error_log("matching request ids found. so granting");
        $request['GRANTED'] = "Y";
        error_log("did the granting work ???? ->" . $request['GRANTED']);

    }
}

日志记录表明$ request ['GRANTED']值设置为Y。

因此，在假设编辑var后，我会读出数组以查看编辑是否成功。

foreach ($_SESSION['chatrequests'] as $request) {
    error_log("reading chat request with id " . $request['ID'] . "  and the incoming request is " . $requestid);
    if ($request['ID'] == $requestid) {
        error_log("matching request ids found. was it granted " . $request['GRANTED']);
    }
}

但是$ request ['GRANTED']仍然设置为N。

问题是我该怎么做？哪种模式可以实现这个目标？

这很正常！你什么时候要求[＆＃39; GRANTED＆＃39;] =＆＃34; Y＆＃34 ;; ，$ _SESSION数组未被修改。你必须这样做：

// accept in session
foreach ($_SESSION['chatrequests'] as $key => $request) {
    error_log("accepting chat request with id " . $request['ID'] . "  and the incoming  request is " . $requestid);
    if ($request['ID'] == $requestid) {
        error_log("matching request ids found. so granting");
        $_SESSION['chatrequests'][$key]['GRANTED'] = "Y";
        error_log("did the granting work ???? ->" . $request['GRANTED']);

    }
}
