如何从Laravel返回的数组中获取键的值
问题描述：
A raw query in Laravel is returning the below output when I print_r() it.
Array ( [0] => stdClass Object ( [AUTO_INCREMENT] => 28 ) )
How can I extract just the value of AUTO_INCREMENT? In this example, the value being 28.
Laravel中的原始查询在print_r（）时返回以下输出。 p>
数组（[0] =＆gt; stdClass对象（[AUTO_INCREMENT] =＆gt; 28）） p> blockquote>
如何只提取AUTO_INCREMENT的值？ 在此示例中，值为28. p> div>
答
The value is a property from a stdClass.
Lets say you have this:
$result; \\your ex
echo $result[0]->AUTO_INCREMENT; \\this would echo 28.
