我一直在尝试创建一个抄袭网页。它将从文本框中获取输入并在 Google 中搜索。如果找到它将显示结果。现在的问题是，它一次搜索整个文本，但我需要一次搜索 10 个单词，并且应该在 10 个单词的循环中搜索到最后。
这是我的代码：
//Google search code
if(isset($_POST['nm'])) {
$query = $_POST["nm"];
$string = str_replace(' ', '%20', $_POST["nm"]);
}
$url = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=".$string;
像这样的事情应该这样做
if(isset($_POST['nm'])) {
$words = explode(' ', $_POST["nm"]);
foreach($words as $word) {
$url = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=". urlencode($word);
//make request
}
}
这会在每个空格上拆分您的字符串，然后生成一个带有字符串编码的 URL。

更新（每 10 个字）：
if(isset($_POST['nm'])) {
$words = explode(' ', $_POST["nm"]);
foreach($words as $wordcount => $word) {
if($wordcount % 10 == 0 && !empty($wordcount)) {
echo 'Hit 10th word, what to do?' . "\n\n";
}
$url = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=". urlencode($word);
echo $url . "\n";
}
}

将字符串拆分为具有一定数量单词的块的一种方法可能是：
[编辑] 更短的方法是：
$text = "This is some text to demonstrate the splitting of text into chunks with a defined number of words.";
$wordlimit = 10;
$words = preg_split("/\s+/",$text);
$strings = array_chunk($words,$wordlimit);
foreach($strings AS $string){
$url = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=". urlencode(implode(" ", $string));
echo $url."\n";
}
不确定，但我认为你必须使用+而不是%20
if(isset($_POST['nm'])) {
$query = implode(' ', array_slice(explode(' ', $_POST['nm']), 0, 10));
$string = urlencode ($query );
}
$url = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=".$string;
