Question

我的代码很好并且运行良好但我必须编写与存储在数据库中相同的术语就像我想要搜索存储在数据库中的名为“awais123”的值一样，我必须将相同的术语写成“awais123” 如果我会写awa或aws它将不会返回任何内容

//我的 datauser.php

<form action="data2.php" method="post" class="navbar-form navbar-right">
  <div class="input-group">
    <input type="Search" name="user_name" value="" placeholder="Search..."    class="form-control" />
     <div class="input-group-btn">
       <button class="btn btn-info">
       <span class="glyphicon glyphicon-search"></span>
       </button>
     </div>
  < /div>
</form>

//现在我的“data2.php”

 <?php 
            include("db/opendb.php"); 
            $username=$_POST['user_name'];

  $query = "SELECT * FROM user WHERE user_name='".$username."'";
   $result = $conn ->query($query) or die("Query error");
 ?>
  <table width="983" border="1" cellpadding="5" class="insertTable">
  <tr>

    <td width="109"><strong>user name</strong></td>

    <td width="38"><strong>user phone no</strong></td>
    <td width="99"><strong>dept id</strong></td>
    <td width="40"><strong></strong></td>
  </tr>
  <?php 
  foreach($result as $row)
  {
  ?>

  <tr>

     <td><?php echo $row['user_name']; ?></td>

      <td><?php echo $row['user_phone_no']; ?></td>
      <td><?php echo $row['dept_id']; ?></td>
      <td><a href="delete.php?id=<?php echo $row['user_name']; ?>">Delete</a>        </td>
  </tr>
     <?php
     }
        ?>

请帮助我，我只想要在我的学期中找到3个单词的显示结果

Answer 1

将$ query更改为： -

$query = "SELECT * FROM user WHERE user_name LIKE '%".$username."'%";

如果2或3个单词与存储的数据库值相同，如何使用php从数据库获取搜索值
