按数组值分组

Question

我正在使用这段代码：

$permissions = array("canview", "canpostthreads", "canpostreplies", "canpostpolls", "all");
foreach($permissions as $permission) {
  for ($i = 1; $i <= 5; $i++) {
    $mode = $_POST['permission'][$i][$permission];
    if($mode == 1) 
      echo "{$permission} = {$i}:::";
  }
}

如果我选中一些复选框，输出是：

canview = 1:::canview = 5:::canpostreplies = 3:::canpostpolls = 5:::

我不希望输出如下：

而不是 canview = 1:::canview = 5:

canview = 1,5

并且如果我'例如：

canpostpolls = 1:::canpostpolls = 2:::canpostpolls = 3

它将是：

canpostpolls = 1,2,3:::canview = 1,5

我希望你们能理解。这是我自己的想法，你可以随意与我分享你的想法，这个数据将导出到mysql表中。

$permissions = array("canview", "canpostthreads", "canpostreplies", "canpostpolls", "all");
$setpermissions = array();
foreach($permissions as $permission) {
  for ($i = 1; $i <= 5; $i++) {
    $mode = $_POST['permission'][$i][$permission];
    if($mode == 1) {
      if (!isset($setpermissions[$permission])) {
         $setpermissions[$permission] = array();
      }
      $setpermissions[$permission][] = $i;
    }
  }
}
$plist = array();
foreach ($setpermissions as $name => $sp) {
   $plist[] = "$name = " . implode(',', $sp);
}
echo implode(':::', $plist);

您需要更多地过滤数据...也许是这样的：

$permissions = array("canview", "canpostthreads", "canpostreplies", "canpostpolls", "all");
$filtered_perms = array();
foreach($permissions as $permission) {
  for ($i = 1; $i <= 5; $i++) {
    $mode = $_POST['permission'][$i][$permission];
    if($mode == 1) {
       if(!is_array($filtered_perms[$permission])) {
         $filtered_perms[$permission] = array();
       }
       $filtered_perms[$permission][] = $i;
  }
}

然后，您可以执行以下操作：

 $final_perms = array();
 foreach($filtered_perms as $key => $val) {
      $final_perms[$key] = implode(",", $val);
  }

希望有帮助！

$permissions = array("canview", "canpostthreads", "canpostreplies", "canpostpolls", "all");
$userPermissions = array();
foreach($permissions as $permission) {
  for ($i = 1; $i <= 5; $i++) {
    $mode = $_POST['permission'][$i][$permission];
    if($mode == 1) 
      $userPermissions[$permission][] = $i;
  }
}
foreach($userPermissions as $permission => $values) {
  echo "{$permission} = " . implode(',', $values) . ":::";
}

您可以执行类似的操作 - 本质上是在输出值之前将它们组合起来。

$permissions = array("canview", "canpostthreads", "canpostreplies", "canpostpolls", "all");
foreach($permissions as $permission) {
  $vals = array();
  for ($i = 1; $i <= 5; $i++) {
    $mode = $_POST['permission'][$i][$permission];
    if($mode == 1) 
      $vals[] = $i;
  }
  if(count($vals))
    echo $permission . ' == ' . implode(',', $vals);
}
