我有以下PHP脚本从用户获取所选的$ empfullname并根据选择打印'timecard_html'。我试图让它有能力，如果他们选择“全部”，那么脚本会在单独的timecard_html中打印出列表中的所有员工。这是php脚本：
if ($empfullname == 'All') {
$query = "select empfullname from ".$db_prefix."employees";
$result = mysql_query($query);
while ($row=mysql_fetch_array($result)) {
$empfullname = ("".$row['empfullname']."");
print timecard_html($empfullname, $local_timestamp_in_week);
unset($empfullname);
}
} else {
print timecard_html($empfullname, $local_timestamp_in_week);
}
此外，如果您需要查看它，请输入timecard_html：
function timecard_html($empfullname, $local_timestamp_in_week) {
// Return html of employee's timecard.
global $show_display_name, $one_week;
// SQL search parameters for one work week.
$begin_local_timestamp = work_week_begin($local_timestamp_in_week);
$end_local_timestamp = $begin_local_timestamp + $one_week;
// Define helper functions for printing timecard header, footer, and for printing every row.
function print_header($tc) {
// Print timecard html header.
global $overtime_week_limit, $timecard_display_running_total;
$overtime_col = $overtime_week_limit > 0 ? "\n <th align=\"center\" class=\"ovt\" title=\"Overtime hours\">OT</th>" : '';
$total_col = $timecard_display_running_total == "yes" ? "\n <th align=\"center\" class=\"total\" title=\"Running total of regular work hours and overtime to date.\">Total</th>" : '';
print <<<End_Of_HTML

截至目前，如果选择“全部”，则会打印表格中第一个员工的结果，但不会打印其他任何员工的结果。此外，如果我只是打印("".$row['empfullname']."")，它会打印出所有员工。我是否可能需要为每个循环使用a而不是while循环？
提前致谢。

您的问题是您在函数中定义了函数。当你调用你的函数时，这将是第一次工作，但第二次它将导致致命的错误，因为函数已经被定义。
将内部函数声明移出main函数应解决此特定问题。
您还应始终在开发时启用错误处理和显示。在这种情况下，您可能会立即发现问题。
将它放在主脚本的顶部：
ini_set('display_errors',1);
error_reporting(E_ALL | E_STRICT);
