First possibility :

第一个可能性:

Array
(
    [collection] => Array
        (
            [links] => Array
                (
                   [id] => 1
                   [url] => www.google.fr
                )              
        )
)

or Second possibility :

或第二种可能性:

Array
(
    [collection] => Array
        (
            [links] => Array
                (
                   [0] => Array
                        (
                            [id] => 1
                            [url] => www.google.fr
                        )
                   [1] => Array
                        (
                            [id] => 2
                            [url] => www.google.fr
                        )
                   [2] => Array
                        (
                            [id] => 3
                            [url] => www.google.fr
                        )
                )              
        )
)

How can I optimise my code for this case ?

我该如何优化我的代码呢?

$url = '';
$nb_results = count($array['collection']['links']);

if($nb_results == 1){
    $url .= $array['collection']['links']['url'];
} else {
    foreach( $array['collection']['links'] as $r){
        $url .= $r['url'].'<br />';
    }
}

If API returns only one result, make an array from this result and use foreach. Thanks to that you don't need to have use if..else when creating $url variable. Look at this code:

如果API只返回一个结果，那么从这个结果创建一个数组并使用foreach。因为你不需要用if.. .当创建$url变量时。看看这段代码:

// checking if links is array; if not - make array with one returned element from API
$data = isset($array['collection']['links'][0]) ? $array['collection']['links'] : array($array['collection']['links']);

foreach( $data as $r)
{
    $url .= $r['url'].'<br />';
}
