Question

我从website下载了GCIDE（GNU项目的CIDE出版物，英语协作国际词典）。

该包包含各种XML文件。我在Windows PC上运行PHP和Apache。如何使用PHP在这些XML文件中搜索单词及其定义？

Answer 1

你的项目引起了我的兴趣，并认为我可能会发现它有用，所以做了一些研究，并找到了下面的code on this page。我运行这个php，目前在我的数据库中有一个功能齐全的字典！

以下是我为完成并运行而做的所有事情（我将XML文件解压缩到包含这些文件的文件夹中名为XML的文件夹中。）

表格的SQL - gcide

CREATE TABLE `gcide` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `word` varchar(255) DEFAULT NULL,
  `definition` text,
  `pos` varchar(50) DEFAULT NULL,
  `fld` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `word` (`word`)
) ENGINE=MyISAM

PHP for gcide XML Import - import_gcide_xml.php

 <?php
    $connection = mysql_connect('localhost', 'root', '') or die('Could not connect to MySQL database. ' . mysql_error());
    $db = mysql_select_db('fiddle',$connection);

    mysql_query('TRUNCATE TABLE gcide') or die(mysql_error());

    $xml = array('xml/gcide_a.xml', 'xml/gcide_b.xml', 'xml/gcide_c.xml', 'xml/gcide_d.xml', 'xml/gcide_e.xml','xml/gcide_f.xml','xml/gcide_g.xml', 'xml/gcide_h.xml', 'xml/gcide_i.xml', 'xml/gcide_j.xml', 'xml/gcide_k.xml', 'xml/gcide_l.xml', 'xml/gcide_m.xml', 'xml/gcide_n.xml', 'xml/gcide_o.xml', 'xml/gcide_p.xml', 'xml/gcide_q.xml', 'xml/gcide_r.xml', 'xml/gcide_s.xml', 'xml/gcide_t.xml', 'xml/gcide_u.xml', 'xml/gcide_v.xml', 'xml/gcide_w.xml', 'xml/gcide_x.xml', 'xml/gcide_y.xml', 'xml/gcide_z.xml');
    $numberoffiles = count($xml);

    for ($i = 0; $i <= $numberoffiles-1; $i++) {
        $xmlfile = $xml[$i];
        // original file contents
        $original_file = @file_get_contents($xmlfile);
        // if file_get_contents fails to open the link do nothing
        if(!$original_file) {}
        else {
            // find words in original file contents
            preg_match_all("/<hw>(.*?)<\/hw>(.*?)<def>(.*?)<\/def>/", $original_file, $results);
            $blocks = $results[0];
            // traverse blocks array
            for ($j = 0; $j <= count($blocks)-1; $j++) {
                preg_match_all("/<hw>(.*?)<\/hw>/", $blocks[$j], $wordarray);
                $words = $wordarray[0];
                $word = addslashes(strip_tags($words[0]));
                $word = preg_replace('{-}', ' ', $word);
                $word = preg_replace("/[^a-zA-Z0-9\s]/", "", $word);
                preg_match_all("/<def>(.*?)<\/def>/", $blocks[$j], $definitionarray);
                $definitions = $definitionarray[0];
                $definition = addslashes(strip_tags($definitions[0]));
                $definition = preg_replace('{-}', ' ', $definition);
                $definition = preg_replace("/[^a-zA-Z0-9\s]/", "", $definition);
                preg_match_all("/<pos>(.*?)<\/pos>/", $blocks[$j], $posarray);
                $poss = $posarray[0];
                $pos = addslashes(strip_tags($poss[0]));
                $pos = preg_replace('{-}', ' ', $pos);
                $pos = preg_replace("/[^a-zA-Z0-9\s]/", "", $pos);
                preg_match_all("/<fld>(.*?)<\/fld>/", $blocks[$j], $fldarray);
                $flds = $fldarray[0];
                $fld = addslashes(strip_tags($flds[0]));
                $fld = preg_replace('{-}', ' ', $fld);
                $fld = preg_replace("/[^a-zA-Z0-9\s]/", "", $fld);

                $insertsql = "INSERT INTO gcide (word, definition, pos, fld) VALUES ('$word', '$definition', '$pos', '$fld')";
                $insertresult = mysql_query($insertsql) or die(mysql_error());

                echo $word. " " . $definition ."\n";
            }
        }
    }
    echo 'Done!';
?>

用于jQuery搜索的PHP - gcide_search.php

    if (isset($_POST['search'])) {
        $db = new pdo("mysql:host=localhost;dbname=fiddle", "root", "");
        // never trust what user wrote! We must ALWAYS sanitize user input
        $word = mysql_real_escape_string($_POST['search']);
        $query = "SELECT * FROM gcide WHERE word LIKE '" . $word . "%' ORDER BY word LIMIT 10";
        $result = $db->query($query);
        $end_result = '';
        if ($result) {
            while ( $r = $result->fetch(PDO::FETCH_ASSOC) ) {
                $end_result                 .= '<dt>' . $r['word'];
                if($r['pos'])   $end_result .= ',&nbsp;<span class="pos">'.$r['pos'].'</span>';
                $end_result                 .= '</dt>';
                $end_result                 .= '<dd>';

                $end_result                 .= $r['definition'];
                $end_result                 .= '</dd>';
            }

Answer 2

我偶然会偶然发现这个PHP and AJAX example - 它可能会让你指向正确的方向，但是如果有这么多数据，你可能会考虑将它导入数据库并使用它的搜索功能 - 这就是他们的设计目标，而性能可能是一个问题，通过XML文件的那么多纯文本。查看this answer进行XML导入。还找到了这个关于importing GCIDE XML的答案。
