Question

我有以下数组$myarr和$ url值：

$url = "http://www.example.com/jane-doe/testingideas.html";


stdClass Object
(
    [items] => Array
        (
            [0] => stdClass Object
                (
                    [updated] => 2015-01-08 17:22:23.279210
                    [url] => http://www.example.com/jane-doe/testingideas.html
                    [score] => 21.053322

                )

            [1] => stdClass Object
                (
                    [updated] => 2015-01-08 17:22:23.279226
                    [url] => http://www.example.com/john-doe/ideas.html
                    [score] => 18.889984
                )
 )

)

该数组有超过2000个值。我复制了2来简化事情。我需要根据URL检索分数。这是我写的代码：

  $myarr = $output->items;
    foreach ($myarr as $val){
       if ($val->url == $url ) {
       $score = round($val->score); 
    } else $score = 'N/A';
    }

这不起作用，因为即使URL匹配也找不到任何分数。

我还修剪了两个网址以删除任何空格，但我遇到了同样的问题。

Answer 1

您在每个循环中取消设置$score，您最好这样做：

$myarr = $output->items;
$score = 'N/A';
foreach ($myarr as $val){
    if ($val->url == $url ) {
       $score = round($val->score); 
    }
}

Answer 2

这应该适合你：

foreach ($myarr as $items) {
    foreach($items as $item) {

        if ($item->url == $url ) {
            $score = round($val->score); 
        } else {
            $score = 'N/A';
        }

    }
}

Answer 3

$url = "http://www.example.com/jane-doe/testingideas.html";
$myarr = $output->items;
foreach ($myarr as $val){
   if (strcmp($val->url,$url) == 0) {
        $score = round($val->score); 
   } else {
        $score = 'N/A';
   }
}

Answer 4

尝试使用trim()确保没有过多的空格：

if (trim($item->url) == trim($url))

如果URL在PHP中匹配，则从数组返回值
