我正在做一个自定义搜索结果页，其中包含从搜索查询前后的\\u content（）中提取一些单词的函数。（例如？s=冷结果=[…昨天是cool 和par…]

它正在工作，但我只获取内容中最后一项的摘录。

how to find position for each item found ? 我知道逻辑，但不知道如何正确编码，不想使用任何像revelanssi这样的插件。

最好的方法是什么？

我的代码functions.php

function show_search_blog(){
    $title = get_the_title();
    // change case for better results
    $mystring = strtolower($title);
    $findme   = get_search_query();
    $pos = strpos($mystring, $findme);
    // vars
    $newContent = $exctractBeforeQuery = $exctractAfterQuery = \'\';
    //
    if ($pos === false) {
        $link = get_the_permalink();
        $newContent .= "<a href=\'".$link."\'>".$title."</a> ";
        // search without tags
        $content = wp_strip_all_tags(get_the_content());

        $pos = strpos($content, $findme);
        // $pos return only value for the last found
        // place for the loop for each keyword found
        if($pos==\'\'){
        $newContent .= "(Debug : keyword found in tags (like in href link attr)<br>";
        //ignore search query in tags
            }
        else{
            $newContent .= "(Debug : Position".$pos.") - ";
            $exctractAfterQuery = substr($content,($pos+strlen($findme) ),40);
            $exctractBeforeQuery = substr($content,$pos-40,40);
            $newContent .= "[...".$exctractBeforeQuery.\'<strong class="search-highlight">\'.$findme."</strong>".$exctractAfterQuery."...]<br>";
            }
        } 
    else{
    $keys = implode(\'|\', explode(\' \', get_search_query()));
    $title = preg_replace(\'/(\' . $keys .\')/iu\', \'<strong class="search-highlight">\\0</strong>\', $title);
        $link = get_the_permalink();
        $newContent .= "<a href=\'".$link."\'>".$title."</a><br>";
    }
  return $newContent;   
}
