Question

嘿大家所以我试图循环遍历现有数组，然后在满足某些条件的情况下将该数组中的数据添加到新数组中。这是我当前的代码，但它不起作用。我不知道如何去做我想做的事。

$allClientArr = $authPartner->getmyClients();

foreach($allClientArr as $client){
  if($client->get('status') == "AC"){
    $clientArr += $client;
  }
}

我在页面中使用了clientArr的元素。

Answer 1

这不是你在PHP中的表现。您的代码应如下所示：

$allClientArr = $authPartner->getmyClients();
$clientArr = array(); // make sure you define $clientArr as an array

foreach($allClientArr as $client){
  if($client->get('status') == "AC"){
    $clientArr[] = $client; // this is how you add element to array
  }
}

Answer 2

该行

$clientArr += $client;

将尝试将值添加到变量中。如果您要将$client添加到$clientArr，请尝试

$clientArr[] = $client;

Answer 3

如果您使用的是PHP 5.5，那么我有两个答案：

 $allClientArr = $authPartner->getmyClients();
 $clientArr = array(); // make sure you define $clientArr as an array
 foreach($allClientArr as $client){
 if($client->get('status') == "AC"){
 $clientArr[] = $client; // this is push the variable $client into the array $clientArr[]
 }
}

但如果您使用php 5.4，请执行：

$allClientArr = $authPartner->getmyClients();
 $clientArr = array(); // make sure you define $clientArr as an array
 foreach($allClientArr as $client){
 if($client->get('status') == "AC"){
 array_push($clientArr[], $client); // this is push the variable $client into the array $clientArr[] in another word it add it in the end of the array
 }
}

使用foreach循环遍历数组并将结果放入新数组
