Answer 1

%20 提示该字符串很可能是 Url 编码的（%20 是单个 space 字符）。所以你可能应该做的是首先尝试 Url 解码字符串（然后你将得到原始字符串）。然后你可以 remove/replace 任何你不想要的字符。

所以在你的问题中，你说你不想要 %20（一个 space）而是一个破折号 (-)。这可以通过以下方式实现...

  <?php 
    error_reporting("0");
     $rowperpage =10 ;
    @$select_city=$_GET['city'];
    if(isset($_REQUEST['search'])){

     $allcount_query = "SELECT count(*) as allcount FROM inventory_details";

                $allcount_result = mysqli_query($conn, $allcount_query);
                $allcount_fetch = mysqli_fetch_array($allcount_result);
                $allcount = $allcount_fetch['allcount'];

     $sql="SELECT * FROM inventory_details";


       $search_item = mysqli_real_escape_string($conn, $_REQUEST['search_box']);

       $sql .= " WHERE (firm_name LIKE '%$search_item%'";
        $sql .= " OR catagory_name LIKE'%$search_item%'";
        $sql .= " OR mobile_no LIKE'%$search_item%'";
          $sql .= " OR product_key LIKE'%$search_item%')";
           $sql .= " AND city='$select_city' AND status='0' ";
           $sql .="ORDER BY today_date DESC limit 0,$rowperpage";

           // $sql .=  " ORDER BY catagory_name LIMIT 0,5";
           // echo $sql;
         if($_GET['search_box']==""){
          $msg=include"error_msg.php";
         }

       else{
         $fquery=mysqli_query($conn, $sql); 
         $totalrec=mysqli_num_rows($fquery);

       if ($totalrec=='0'){
        $msg=include"error_msg.php";
       }
       }

    }
    //   if($selct_city=$_GET['city']){
    // SELECT * FROM inventory_details WHERE city LIKE '%DELHI%' && catagory_name LIKE '%belts%'
    //    SELECT * FROM inventory_details WHERE firm_name='keyboard' OR catagory_name='keyboard' OR mobile_no='keyboard' OR city='keyboard' OR product_key='keyboard' && city="delhi"

您可能应该使用 htmlspecialchars.

对您回显给浏览器的任何内容进行编码

免责声明：我测试 PHP 代码的网站在使用 rawurldecode('hi%20you'); 和 urldecode('hi%20you'); 时给出了相同的结果。

从 php 中的 url 移除 %20

remove %20 from url in php

php

urlencode

urldecode
