SOUND LIKE 条件只是比较两个单词的 SOUNDEX 键,您可以使用 PHP soundex() 函数生成相同的键。
因此,如果您找到匹配的行并需要找出要突出显示的单词,您可以同时获取名字和姓氏,然后使用 PHP 查找匹配的行并仅突出显示该单词。
我制作这段代码只是为了尝试一下。(必须测试我的理论xD)
<?php
// A space seperated string of keywords, presumably from a search box somewhere.
$search_string = 'John Doe';
// Create a data array to contain the keywords and their matches.
// Keywords are grouped by their soundex keys.
$data = array();
foreach(explode(' ', $search_string) as $_word) {
$data[soundex($_word)]['keywords'][] = $_word;
}
// Execute a query to find all rows matching the soundex keys for the words.
$soundex_list = "'". implode("','", array_keys($data)) ."'";
$sql = "SELECT id, firstname, lastname
FROM sounds_like
WHERE SOUNDEX(firstname) IN({$soundex_list})
OR SOUNDEX(lastname) IN({$soundex_list})";
$sql_result = $dbLink->query($sql);
// Add the matches to their respective soundex key in the data array.
// This checks which word matched, the first or last name, and tags
// that word as the match so it can be highlighted later.
if($sql_result) {
while($_row = $sql_result->fetch_assoc()) {
foreach($data as $_soundex => &$_elem) {
if(soundex($_row['firstname']) == $_soundex) {
$_row['matches'] = 'firstname';
$_elem['matches'][] = $_row;
}
else if(soundex($_row['lastname']) == $_soundex) {
$_row['matches'] = 'lastname';
$_elem['matches'][] = $_row;
}
}
}
}
// Print the results as a simple text list.
header('content-type: text/plain');
echo "-- Possible results --\n";
foreach($data as $_group) {
// Print the keywords for this group's soundex key.
$keyword_list = "'". implode("', '", $_group['keywords']) ."'";
echo "For keywords: {$keyword_list}\n";
// Print all the matches for this group, if any.
if(isset($_group['matches']) && count($_group['matches']) > 0) {
foreach($_group['matches'] as $_match) {
// Highlight the matching word by encapsulatin it in dashes.
if($_match['matches'] == 'firstname') {
$_match['firstname'] = "-{$_match['firstname']}-";
}
else {
$_match['lastname'] = "-{$_match['lastname']}-";
}
echo " #{$_match['id']}: {$_match['firstname']} {$_match['lastname']}\n";
}
}
else {
echo " No matches.\n";
}
}
?>
一个更通用的函数,从字符串中提取匹配的 soundex 词可能如下所示:
<?php
/**
* Attempts to find the first word in the $heystack that is a soundex
* match for the $needle.
*/
function find_soundex_match($heystack, $needle) {
$words = explode(' ', $heystack);
$needle_soundex = soundex($needle);
foreach($words as $_word) {
if(soundex($_word) == $needle_soundex) {
return $_word;
}
}
return false;
}
?>
如果我理解正确,可以在您之前发布的代码中使用它:
foreach ($find_array as $term_to_highlight){
foreach ($result as $key => $result_string){
$match_to_highlight = find_soundex_match($result_string, $term_to_highlight);
$result[$key]=highlight_stuff($result_string, $match_to_highlight);
}
}
这不会像第一个片段中更有针对性的代码那样有效。
