我从其 website 下载了 GCIDE(GNU 项目的 CIDE 出版物，国际英语协作词典)。 .
包中包含各种 XML 文件。我在我的 Windows PC 上运行 PHP 和 Apache。我如何使用 PHP 在这些 XML 文件中搜索单词及其定义？
最佳答案
您的项目引起了我的兴趣，并认为我可能会在某个时候发现它有用，因此进行了一些研究，并找到了以下内容 code on this page .我运行了这个 php，目前我的数据库中有一个功能齐全的字典!
这是我为启动和运行它所做的一切(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)。
用于表的 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
用于 gcide XML 导入的 PHP - 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!';
