我有一个包含 13 个元素的数组
$vcpes=
array:13 [▼
0 => array:23 [▼
"cpe_mac" => "665544332211"
"bandwidth_max_up" => 300000
"bandwidth_max_down" => 500000
"filter_icmp_inbound" => null
"dmz_enabled" => null
"dmz_host" => null
"vlan_id" => null
"dns" => []
"xdns_mode" => null
"cfprofileid" => null
"stub_response" => null
"acl_mode" => null
"portal_url" => null
"fullbandwidth_max_up" => null
"fullbandwidth_max_down" => null
"fullbandwidth_guaranty_up" => null
"fullbandwidth_guaranty_down" => null
"account_id" => 1000 // <--- Keep
"location_id" => null
"network_count" => null
"group_name" => null
"vse_id" => null
"firewall_enabled" => null
]
1 => array:23 [▼

我想删除那些有account_id == null.
我试图解码它：
$vcpes = json_decode (json_encode ( $vcpes), FALSE);
并检查它：
foreach($vcpes as $vcpe){
if($vcpe->account_id == null){
//delete it
}else{
//don't delete it
}
}
我希望有人能给我一点提示。
->用于获取对象的属性。要从数组中获取值，请使用$array['key']表示法。
foreach($vcpes as $i => $vcpe){
if ($vcpe['account_id'] === null) {
unset($vcpes[$i]);
}
}
您可以尝试这种方式，或者仅使用array_filter() Baker评论@Mark
$finalArray = [];
foreach($vcpes as $vcpe){
if($vcpe->account_id != null){
$finalArray[] = $vcpe;
}
}
print '<pre>';
print_r($finalArray);
print '</pre>';
