preg_replace-这些单词中的哪一个引起了问题

我正在尝试在我的网站上"查找和替换"词汇表术语。

这些术语取自我的数据库，并像这样从一个简单的字符串数组中构建：

/* get the glossary terms */
$results = $wpdb->get_results( 'SELECT post_title AS list FROM wp_posts WHERE post_status="publish" AND post_type="glossary" AND post_parent>0' );
$glossary_terms = array();
foreach ( $results as $row ) {
    $term = preg_quote( str_replace( array("/", "'"), array("/", """), $row->list ) );
    $glossary_terms[] = $term;
}

此$glossary_terms用作以下函数中的$glossary：

$urls    = array();
$pattern = array();
// build a normalized lookup (case-insensitive, whitespace-agnostic)
foreach ($glossary as $term) {
    $term_norm = preg_replace('/'s+/', ' ', strtoupper(trim($term)));
    $pattern[] = preg_replace('/ /', '''s+', preg_quote($term_norm));
    $initial = substr($term, 0, 1);
    $urls[$term_norm] = '/dev/glossary/' . $initial . '/' . rawurlencode($term);
    $rels[$term_norm] = '/dev/glossary/' . $initial . '/' . rawurlencode($term) . '?preview=true';
    $title[$term_norm] = $term;
}
$pattern  = '/'b(' . implode('|', $pattern) . ')'b/i';

现在，$pattern正在显示这个单词列表。其中的一段摘录，包括我认为可能给我带来问题的几个词，是：

MANGROVE''s+TREE|MANTLE|MARACYN|MARACYN''-2|MARBLED|MARGIN|MARGINAL|MARINE|MOTROPHY|MATURE|MAXILLA|MAXILRAY|MEANDER|MEDIAL|MEDIAN|MELANIN|MELANOPHORE|MEMBRANE|MENISCUS|MENTAL|MENTAL''s+BARBEL|MERISTIC|MERISTICS|MERISTIC''s+CHARTER|MESETHMOID|MESIAL|MESO''-|MESOCORACOID|META''-|代谢|代谢'' s+蓝色|微生物|微生物捕食者|微生物|微小陨石|迁移率|MIGRATION | MILLITRE''s+''

我遇到的问题是，过滤器正在失控，链接$content中的每一个空格和单词。

我的问题是$pattern中的哪些术语（根据pastebin/摘录）导致了这个问题？我怀疑这与'和BAUDELOT'S's+LIGAMENT有关，但我不确定如何纠正这一点，因为preg_quote似乎无法逃脱撇号？

EDIT这是附加代码，用于尝试确定这是否是问题所在，而不是preg_replace:

$text_nodes = $xpath->query('//text()[not(ancestor::a)]');
foreach($text_nodes as $original_node) {
    $text     = $original_node->nodeValue;
    $hitcount = preg_match_all($pattern, $text, $matches, PREG_OFFSET_CAPTURE);
    if ($hitcount == 0) continue;
    $offset   = 0;
    $parent   = $original_node->parentNode;
    $refnode  = $original_node->nextSibling;
    $parent->removeChild($original_node);
    foreach ($matches[0] as $i => $match) {
        $term_txt = $match[0];
        $term_pos = $match[1];
        $term_norm = preg_replace('/'s+/', ' ', strtoupper($term_txt));
        // insert any text before the term instance
        $prefix = substr($text, $offset, $term_pos - $offset);
        $parent->insertBefore($document->createTextNode($prefix), $refnode);
        // insert the actual term instance as a link
        $link = $document->createElement("a", $term_txt);
        $link->setAttribute("href", $urls[$term_norm]);
        $link->setAttribute("rel", $rels[$term_norm]);
        $link->setAttribute("class", "link_glossary");
        $parent->insertBefore($link, $refnode);
        $offset = $term_pos + strlen($term_txt);
        if ($i == $hitcount - 1) {  // last match, append remaining text
            $suffix = substr($text, $offset);
            $parent->insertBefore($document->createTextNode($suffix), $refnode);
        }
    }
}

提前感谢，
