Php 和 Mysql 搜索问题

Question

以下是我的 search.php 代码:

<?php
if(isset($_POST['action']) && $_POST['action'] == "Search Question")
{
$search = mysql_real_escape_string(trim(htmlspecialchars($_POST['search'])));   
$err = array();

if(isset($search))
    {   
            if(empty($search))
                $err[] = "Please write your question name";
            elseif(is_numeric($search))
                $err[] = "Wrong values entered";
        }   
        if(!empty($err))
        {
            foreach($err as $er)
            {
                echo "<font color=red>$er<br/></font>"; 
            }
        }
        else
        {

            $search_sql = mysql_query("SELECT * FROM questions WHERE q_name LIKE '%$search%'");


            //$search_sql = mysql_query("SELECT * FROM questions WHERE MATCH(q_name, answer) AGAINST  '$search' ");             
            $numserach = mysql_num_rows($search_sql);

            if($numserach == 1)
            {
                echo "<font color='green'><strong>$numserach Question found</strong></font><br/>";
                while($result = mysql_fetch_array($search_sql))
                {
                    $subid = $result['sub_id'];
                    $id = $result['id'];
                    $qquestionsname = $result['q_name'];

                    ////////////////////////////////////////////////// SEARCH SHOW START HERE ///////////////////////
                    //include("toppagi.php");
                    $questions = $result['q_name']; 
                    echo "<a href='answerdetails.php?id=$id&subid=$subid&questionname=$qquestionsname'>$questions</a><br/>";
                    //include("bottompagi.php");
                    ////////////////////////////////////////////////// SEARCH SHOW END HERE ///////////////////////
                }
            }
            else
            {
                echo "<font color=red>No Result Found</font>";
            }

        }   
    }
    ?>

在我的数据库中，我试图搜索存储我所有问题名称的“q_name”文件。比如.. 会计、书籍、O level、测试 o level 等。

好吧，但是如果我搜索诸如 ac 或 te 之类的内容，那么它不会显示任何结果。我需要如果我搜索 ac 或 te 或其他内容，那么它会显示一些结果..

提前致谢:)

使用此行

  if($numserach > 0)
  {.....

而不是

  if($numserach == 1)
  {.....
