Question

我使用$ GLOBALS来全局化变量data3，reg，kok和random ..但是当我运行代码时，它只是显示未定义的变量。

我到处都在寻找答案，但找不到任何东西。


<?php

if (isset($_POST['kraje'])){
  $globals['$reg'] = $_POST['kraje'];
  echo $reg;
}
if (isset($_POST['okresi'])) {
  $GLOBALS['$kok'] = $_POST['okresi'];
  echo $kok;
}
    // volba okresů
          function okresi(){
$connection = mysqli_connect("localhost", "root", "", "uzemnicelkycr");
mysqli_set_charset($connection,"utf8");
$sql = 'SELECT nazev, id FROM okres';
$res = mysqli_query($connection, $sql);
$data = array();
$adata = array();
echo "Volba okresu: ";
echo "<select name='okresi'>";
if (mysqli_num_rows($res) > 0) {
    while ($row = mysqli_fetch_assoc($res)) {
      $data[] = $row['nazev'];
      $adata[] = $row['id'];
      echo '<option value=" '.$row['id'].'">'.$row['nazev'].'</option>';
        }
}
echo "</select> ";
}

  //volba krajů
          function kraje(){
$connection = mysqli_connect("localhost", "root", "", "uzemnicelkycr");
mysqli_set_charset($connection,"utf8");
$sqn = 'SELECT nazev, id FROM kraj';
$data2 = array();
$adata2 = array();
$resolution = mysqli_query($connection, $sqn);
echo "Volba kraje: ";
echo "<select name='kraje'>";
if(mysqli_num_rows($resolution) > 0){
    while ($rows = mysqli_fetch_assoc($resolution)) {
      $adata2[] = $rows['id'];
      $data2[] = $rows['nazev'];
      echo '<option value=" '.$rows['id'].'" >'.$rows['nazev'].'</option>';
    }
}
echo "</select>";
}
  //náhodná obec
          function pick(){
$connection = mysqli_connect("localhost", "root", "", "uzemnicelkycr");
mysqli_set_charset($connection,"utf8");
$sin = 'SELECT kraj_id, okres_id, nazev FROM obec';
$reso = mysqli_query($connection, $sin);
$GLOBALS['$data3'] = array();
if (mysqli_num_rows($reso) > 0) {
  while($rowss = mysqli_fetch_array($reso,MYSQL_ASSOC)){
    $data3[] = $rowss;
}

}

$GLOBALS['$random'] = array_rand  ($data3);
echo $data3[$GLOBALS['$random']]['nazev'];
}
  //kontrola
        function control($data3, $reg, $kok, $random){
if($data3[$random]['kraj_id'] == $reg && $data3[$random]['okres_id'] = $kok){

  echo "Výhra";
  }
else{

echo "Špatně";
}

}
control($data3, $reg, $kok, $random);
?>
