Question

这是我拥有的数组

var_dump($arr);
// prints below array
[0] => Array
        (
            [title] => Lee Daniels' The Butler (2013)
        )

我想删除括号中的年份，并用下划线（“_”）替换空格（“”），然后对其进行urlencode。因此，期望的输出是

Lee_Daniels％27_The_Butler

这是我的代码：

$url = preg_replace('/\((\d){4}\)/', '', $arr[0]['title']);

$title = str_replace(" ","_", trim($url));
$title = urlencode($title); // tried with urlencode(addslashes($title));
echo $title; // prints Lee_Daniels'_The_Butler

我知道echo urlencode（'\''）给出“％27”，因此尝试使用addslashes但无济于事。

更新它适用于

preg_replace('/\((\d){4}\)/', '', "Lee Daniels' The Butler (2013)");

但是如果你直接获取str如下：

include_once('simple_html_dom.php');

$url = 'http://www.imdb.com/chart/';
$main_content = file_get_html($url);

$table = $main_content->find('table', 0);
$tbody = $table->find('tbody', 0);

$trs = $tbody->find('tr');
foreach ($trs as $tr) {
    $tds = $tr->find('td');
    $movies = "";

    $movies['title'] = trim($tds[2]->plaintext);

    $arr[] = $movies;
}

$url = preg_replace('/\((\d){4}\)/', '', $arr[0]['title']);

$title = str_replace(" ","_", trim($url));
$title = urlencode($title);
echo $title;

要复制这个，请在php中包含简单的html dom解析器。

有人可以指出我所缺少的东西吗？

以下是工作代码：

include_once('simple_html_dom.php');

$url = 'http://www.imdb.com/chart/';
$main_content = file_get_html($url);

$table = $main_content->find('table', 0);
$tbody = $table->find('tbody', 0);

$trs = $tbody->find('tr');
foreach ($trs as $tr) {
    $tds = $tr->find('td');
    $movies = "";

    $movies['title'] = trim($tds[2]->plaintext);

    $arr[] = $movies;
}

$title = html_entity_decode($arr[0]['title'], ENT_QUOTES, 'UTF-8');
$title = trim(preg_replace('/\((\d){4}\)/', '', $title));
$title = str_replace(" ", "_", $title);
$title = urlencode($title);

echo $title;
