我对PHP比较陌生，我很想知道某个功能是否可行。我有一个关键字搜索，结果页面的代码在上面。我想在页面上出现$ kword变量的地方加粗。这可能吗？

Answer 1

您可以创建一个函数来执行此操作，并在回显变量之前调用它。

而不是：$info['question']使用boldText($info['question'], $kword)

function boldText($text, $keyword) {
    return str_ireplace($keyword, "<strong>$keyword</strong>", $text);
}

作为旁注，在SQL查询中使用它之前不要忘记使用mysql_real_escape_string()转义$kword，或者更好，请考虑使用MySQLi or PDO，因为强烈建议不要使用mysql扩展名

Answer 2

你能在每个Print语句中使用这样的东西吗？

str_replace($kword, "<b>$kword</b>", $info[...])

（或CSS，例如＆lt; span style ='font-weight：bold'＆gt; ...＆lt; / span＆gt; 如果你愿意的话。）

在整个页面中用PHP标记特定变量
