如何删除null或空数组？谢谢

Image example

我的代码

$ar = array( 
'id_cs'               =>$row['AN'], 
'nama'                =>$row['AO'], 
'tlp'                 =>$row['AP'], 
'alamat_detail'       =>$row['AQ'], 
'id_provinsi'         =>$prov, 
'id_kota'             =>$kot, 
'id_kecamatan'        =>$kec, 
'id_kelurahan'        =>$kelurahans, 
);

foreach($ar as $key => $value)
if(empty($value)){
unset($ar[$key]);

}
echo '<pre>', print_r($ar);

输出图像。

我想要这样的输出

Array
(
    [id_cs] => 16
    [nama] => PT. xx
    [tlp] => xx
    [alamat_detail] => JL. MAYJEN SUTOYO
    [id_provinsi] => 1
    [id_kota] => 4
    [id_kecamatan] => 32
    [id_kelurahan] => 205
)
1

Array
(
    [id_cs] => 16
    [nama] => PT. xxxxx
    [tlp] => xxxxx
    [alamat_detail] => JL. MAYJEN SUTOYO
    [id_provinsi] => 1
    [id_kota] => 4
    [id_kecamatan] => 32
    [id_kelurahan] => 205
)

如何通过删除null或空数组来实现此目的。谢谢

答案

您可以这样操作：

if(empty($prov) && empty($kot) && empty($kec) && empty($kelurahans)){
   $prov = 1;
   $kot = 4;
   $kec = 32;
   $kelurahans = 205;
} //Of course you can divide this check in to a separate checks to get a separate changes on variables

$ar = array( 
   'id_cs'               =>$row['AN'], 
   'nama'                =>$row['AO'], 
   'tlp'                 =>$row['AP'], 
   'alamat_detail'       =>$row['AQ'], 
   'id_provinsi'         =>$prov, 
   'id_kota'             =>$kot, 
   'id_kecamatan'        =>$kec, 
   'id_kelurahan'        =>$kelurahans, 
);

foreach($ar as $key => $value)
   if(empty($value)){
     unset($ar[$key]);
   }
}
echo '<pre>', print_r($ar);

您将获得所需的输出：

Array
(
    [id_cs] => 16
    [nama] => PT. xx
    [tlp] => xx
    [alamat_detail] => JL. MAYJEN SUTOYO
    [id_provinsi] => 1
    [id_kota] => 4
    [id_kecamatan] => 32
    [id_kelurahan] => 205
)
