我正在使用语言分类器的 API。我创建分类器,添加两个类,训练它们,然后发送一个要分类的字符串。分类调用的响应是一个数组:
$response = $uclassify->classify($bigString, $title);
print_r($response);
在响应上调用 print_r 会打印以下字符串(我已对其进行了标记以尝试理解它):
Array (
[0] => Array (
[id] => Classify12911363801322
[classification] => Array (
[0] => Array (
[class] => Cool [p] => **0.636574**
)
[1] => Array (
[class] => Uncool [p] => **0.363426**
)
) [text] =>
)
)
我感兴趣的数组的唯一部分是数字(以粗体突出显示)。如何编写打印语句来提取这两个数字?
编辑:未修改的 print_r:
Array ( [0] => Array ( [id] => Classify12911363801322 [classify] => Array ( [0] => Array ( [class] => Cool [p] => 0.636574 ) [1] => Array ( [ class] => Uncool [p] => 0.363426 ) ) [text] => 海量文本字符串))
