我可能只是做了一些愚蠢的事情,但我看不出错误的原因。我在用PHP编写的分页函数中的for循环上得到Parse错误;继承人完全错误。
PHP Parse error: parse error, expecting `')'' in /Users/danielsgroves/Sites/Gouland/search.php on line 95
发生错误的完整功能如下:
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 $pagination;
}
正如您可能已经根据我所说的那样建立了错误上提到的第95行for ($i = 0; $
等。完整的类文件如下所示。我已经将评论包括在内,只是有帮助。
Class BingSearch
{
private $APPID = "SOME API KEY";
private $keyword;
private $scope;
private $page;

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;
}
}
要使用此功能,这是运行的PHP。
require 'search.php';
$search = new BingSearch($query, $source, $query);
$search->getResults();
有没有人喜欢把我指向正确的方向,这可能是一个非常小的东西,我在看了太长时间之后就错过了。
谢谢,

for ($i = 0; $i < $pages; i++)
你忘了$,用$ i ++替换i ++。
答案 1 :(得分: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>";
}
你错过了循环中的$
for ($i = 0; $i < $pages; $i++) {
$pagination .= "<li><a id=\"a$i\" class=\"na\" href=\"?q=$keyword&scope=$scope&page=$i\">$i</a></li>";
}

您忘记了加号$i
的美元符号。
private function pagination($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;
}

在该行中,将i++
替换为$i++
。它缺少$字符。
