我得到了一个数组的结果：

我想知道的是如何把它作为一个单独的变量取出来？？
有人能帮我吗？
找了两天了，还是没有结果

我认为你首先需要使用像curl，file_get_contents这样的函数向API端点发出请求，或者像Guzzle这样的PHP包可以随意使用任何一个，正如我看到的那样，你已经得到了响应，所以然后使用json_decode函数将其解码为JSON并访问数据。
下面是一个示例代码片段，演示了如何在PHP中从OKEx API响应中提取数据：

// Set up API request
$apiKey = 'your-api-key';
$apiSecret = 'your-api-secret';
$endpoint = 'https://www.okex.com/api/v5/account/balance';
$timestamp = time();
$signString = $timestamp . 'GET/api/v5/account/balance';
$signature = hash_hmac('sha256', $signString, $apiSecret);

// Set up cURL request
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $endpoint);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, [
    'OK-ACCESS-KEY: ' . $apiKey,
    'OK-ACCESS-SIGN: ' . $signature,
    'OK-ACCESS-TIMESTAMP: ' . $timestamp,
    'OK-ACCESS-PASSPHRASE: your-passphrase'
]);

// Execute cURL request and decode response
$response = curl_exec($curl);
$data = json_decode($response, true);
curl_close($curl);

// Extract data from response
if (isset($data['code']) && $data['code'] === 0) {
    $balances = $data['data'];
    foreach ($balances as $balance) {
        echo $balance['currency'] . ': ' . $balance['total'] . PHP_EOL;
    }
} else {
    echo 'Error: ' . $data['msg'] . PHP_EOL;
}

请注意，您需要修改代码以匹配您请求的特定API端点和您想要从响应中提取的数据，但您必须查看将foreach放置在何处以及如何保护它，因为响应并不总是相同的。
