我的问题是我想在循环外回显 $problem。当我这样做时，它只包含 1 个值。所以我想有什么解决方案可以让我在括号外解决 $problem。就像我们都可以在启动模式中看到的那样对于删除，我尝试回显 $problem 但结果很喜欢我说只携带 1 个值而不是数组......所以我希望你们可以成为我的向导，谢谢......

像这样：

$problem=array();
while (($row = oci_fetch_row($stid)) != false) {
  $problem[]=$row[1];
}

foreach($var in $problem){
  echo $var . "<br />"
}
