Php 按数组值分组

我正在使用以下代码：

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

我不希望输出如下所示：

而不是

canview=1:：：canview=5:

canview = 1,5

例如，如果我有：

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

它将是：

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

---

希望你们能理解。这是我自己的想法，您可以自由与我分享您的想法，这些数据将导出到mysql表。

您需要进一步过滤数据。。。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;
  }
}

希望有帮助

$permissions=array（“canview”、“canpostthreads”、“canpostreplies”、“canpostpolls”、“all”）；
$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) . ":::";
}

$userPermissions=array（）；
foreach（$permissions作为$permission）{
对于（$i=1；$i$值）{
echo“{$permission}=”.introde（'，'，$values）。：”；
}

您可以执行类似的操作—基本上，在输出值之前组合这些值

$permissions = array("canview", "canpostthreads", "canpostreplies", "canpostpolls", "all");
foreach($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);
}

$permissions=array（“canview”、“canpostthreads”、“canpostreplies”、“canpostpolls”、“all”）；
foreach（$permissions作为$permission）{
$vals=array（）；
对于（$i=1；$i
$permissions=array（“canview”、“canpostthreads”、“canpostreplies”、“canpostpolls”、“all”）；
$setpermissions=array（）；
foreach（$permissions作为$permission）{
对于（$i=1；$i$sp）{
$plist[]=“$name=”。内爆（'，'，$sp）；
}
回声内爆（'：'，$plist）；
如果需要从末尾删除
：：”
，而不是
echo
，可以将所有内容保存到字符串和
rtrim（“：”，$string）
$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) . ":::";
}

$permissions = array("canview", "canpostthreads", "canpostreplies", "canpostpolls", "all");
foreach($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);
}

$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);
