PHP for`loop解析错误

Question

我可能只是在做一些愚蠢的事情，但我看不到错误的原因。我在使用PHP编写的分页函数的for循环中出现Parse错误;继承人的完整错误。

PHP Parse error: parse error, expecting `')'' in /Users/danielsgroves/Sites/Gouland/search.php on line 95 

而全功能的错误是发生在如下：

private function pagination($scope, $keyword) 
{ 
    $pages = 15; 

    $pagination = '<ul>'; 
    for ($i = 0; $i < $pages; i++) { 
     $pagination .= "<li><a id=\"a$i\" class=\"na\" href=\"?q=$keyword&scope=$scope&page=$i\">$i</a></li>"; 
    } 
    $pagination .= '</ul>'; 

    return $pagination; 
} 

正如你可以从我说的错误中提到的线95 for ($i = 0; $等已经建立下面是全班文件。我已经包含评论，只是为了帮助它。

Class BingSearch 
{ 
private $APPID  = "SOME API KEY"; 

private $keyword;

private $results;

public function __construct($keyword, $scope, $page) 
{ 
    $this->keyword = urlencode($keyword); 
    $this->scope = $scope; 
    $this->page  = $page; 
}

    $this->results = json_decode($this->response); 
}

*/ 
private function generateWebResults() 
{ 
    if($this->results->SearchResponse->Web->Total != 0) { 

     foreach($this->results->SearchResponse->Web->Results as $value) { 

      if (!isset($value->Description)) 
       $value->Description = ''; 

      echo "<article>"; 
      echo "<h3><a href=\"$value->Url\" title=\"Go to $value->Title\">$value->Title</a></h3>"; 
      echo "<span class=\"cached\"><a href=\"$value->CacheUrl\" title=\"View Cached Version\">Cached</a></span>"; 
      echo "<p>" . strip_tags($value->Description) . "</p>"; 
      echo "<span class=\"fullLink\"><a href=\"$value->Url\" title=\"Go to $value->Title\">$value->Url</a></span>"; 
      echo "</article>"; 

     } 

    } 
} 

private function pagination($scope, $keyword) 
{ 
    $pages = 15; 

    $pagination = '<ul>'; 
    for ($i = 0; $i < $pages; i++) { 
     $pagination .= "<li><a id=\"a$i\" class=\"na\" href=\"?q=$keyword&scope=$scope&page=$i\">$i</a></li>"; 
    } 
    $pagination .= '</ul>'; 

    return $pagination; 
} 
} 

要使用该功能，这是运行的PHP。

require 'search.php'; 
$search = new BingSearch($query, $source, $query); 
$search->getResults(); 

有谁看上我指明了正确的方向，这可能是一些非常小的，我已经只是错过看它太久之后。

谢谢，

Answer 1

for ($i = 0; $i < $pages; i++) 

你忘了一个$，代替我++与$ I ++。

Answer 2

你的循环

for ($i = 0; $i < $pages; i++) { 
     $pagination .= "<li><a id=\"a$i\" class=\"na\" href=\"?q=$keyword&scope=$scope&page=$i\">$i</a></li>"; 
    } 

你已经错过了$在循环

for ($i = 0; $i < $pages; $i++) { 
     $pagination .= "<li><a id=\"a$i\" class=\"na\" href=\"?q=$keyword&scope=$scope&page=$i\">$i</a></li>"; 
    } 

Answer 3

您忘记了递增$i的美元符号。

private function pagination($scope, $keyword) 
{ 
    $pages = 15; 

    $pagination = '<ul>'; 
    for ($i = 0; $i < $pages; $i++) { 
     $pagination .= "<li><a id=\"a$i\" class=\"na\" href=\"?q=$keyword&scope=$scope&page=$i\">$i</a></li>"; 
    } 
    $pagination .= '</ul>'; 

    return $pagination; 
} 

Answer 4

在该行，以$i++更换i++。它缺少$字符。
