php - 如何回显 stdClass 对象标题

Question

我想要的只是呼应标题。

以下命令由以下触发器打印：

print_r($results);

Array ( 
   [0] => stdClass Object ( [title] => Title A [catid] => 1 ) 
   [1] => stdClass Object ( [title] => Title B [catid] => 1 ) 
) 

我怎样才能呼应标题 A

亲切的问候！

Answer 1

它只是一个对象数组，所以...

$results[0]->title

Answer 2

要仅打印您可以执行的名称：

foreach($results as $result){
    echo($result->title);
}

Answer 3

$results = Array ( 
   [0] => stdClass Object ( [title] => Title A [catid] => 1 ) 
   [1] => stdClass Object ( [title] => Title B [catid] => 1 ) 
);

$str = "";

foreach($arr as $item) {
    $result .= $item->title . "\n";
}

print $str;

类似的东西？
