php - 使用 Google api 时如何循环

Question

以下代码从我设置的 google api 帐户返回 10 个结果，这是 google 一次允许的最大值，但你循环它 10 次。我不想得到 100 个结果

<?php
{
$rootUri = "https://www.googleapis.com/customsear-----";        
$ApiKey = "-------------";
$CustomKey = "----------------";
$query = urlencode("'{$_POST['query']}'");

$start = "1";  // the next loop starts at 11, then 21 until 91

    $link=$rootUri."key=".$ApiKey."&cx=".$CustomKey."&q=".$query."&alt=json"."&start=".$start;

    $ch=curl_init();
    curl_setopt($ch,CURLOPT_URL,$link);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
    $data = curl_exec($ch);
    curl_close($ch);

    $js = json_decode($data); 

    $googleArray = array();                     

    foreach ($js->items as $item)
    {   
        $googleArray[$i]['link'] = ($item->{'link'});           
        $googleArray[$i]['title'] = ($item->{'title'});
        $googleArray[$i]['snippet'] = ($item->{'snippet'});
        $i++;
    }
    print_r ($googleArray);

?>

我可以更改从 $start = 开始的位置，所以基本上我想显示 100 个结果，提前致谢

这是输出

只是一个尝试，但也许它是这样工作的：

$rootUri = "https://www.googleapis.com/customsear-----";        
$ApiKey = "-------------";
$CustomKey = "----------------";
$query = urlencode("'{$_POST['query']}'");


$all_items = array();
for($i=1;$i<100;$i+=10) {

    $start = $i; 
    $link=$rootUri."key=".$ApiKey."&cx=".$CustomKey."&q=".$query."&alt=json"."&start=".$start;

    $ch=curl_init();
    curl_setopt($ch,CURLOPT_URL,$link);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
    $data = curl_exec($ch);
    curl_close($ch);
    $js = json_decode($data); 
    $all_items = array_merge($all_items,$js->items);
}


$googleArray = array();                     

foreach ($all_items as $item)
{   
    $googleArray[$i]['link'] = ($item->{'link'});           
    $googleArray[$i]['title'] = ($item->{'title'});
    $googleArray[$i]['snippet'] = ($item->{'snippet'});
    $i++;
}
print_r ($googleArray);
