Php android中的Google vision API食品标签检测

我正在为android mobile制作一个深入的食品记录应用程序，我想使用google vision API添加一些基本的图像识别

我一直在尝试API和使用PHP，但没有成功。 我一直在看所有的教程，总是在某些问题上卡住

这是我到目前为止在php方面最接近的一次

<?php
# Includes the autoloader for libraries installed with composer
require __DIR__ . '/vendor/autoload.php';

# Imports the Google Cloud client library
use Google\Cloud\Vision\VisionClient;

# Your Google Cloud Platform project ID
$projectId = 'foodlogging-160914';

putenv('GOOGLE_APPLICATION_CREDENTIALS=./FoodLogging-ae7e284eb66e.json');

# Instantiates a client
$vision = new VisionClient([
    'projectId' => $projectId
]);

# The name of the image file to annotate
$fileName = __DIR__ . '/hamburger.jpg';

# Prepare the image to be annotated
$image = $vision->image(fopen($fileName, 'r'), [
    'LABEL_DETECTION'
]);

# Performs label detection on the image file
$labels = $vision->annotate($image)->labels();

echo "Labels:\n";
foreach ($labels as $label) {
    echo $label->description() . "\n";
}
?>

我已经看完了整个文档，但我不知道它为什么会在日期时间方面出现问题，因为我甚至从未使用过它

有没有人有谷歌视觉API的经验可以帮助我？最好是android部分，帮我上路还是帮我开始

谢谢。在php.ini中设置时区

➜  ~ cat/etc/php.ini | grep时区
; 定义日期函数使用的默认时区
; http://php.net/date.timezone
date.timezone=美国/圣保罗

我刚刚在脚本的顶部添加了“日期默认时区设置（'UTC'）”，这也起到了作用！谢谢我刚刚在我的脚本顶部添加了“日期\默认值\时区\设置（'UTC'）；”，这也起到了作用！谢谢
