$dbconnect=mysqli_connect($hostname,$username,$password,$db);如果($dbconnect->connect_error){die("数据库连接失败:" . $dbconnect->connect_error);}$query=mysqli_query($dbconnect,"SELECT DISTINCT companyname,client_id,feedback,status from review WHERE status=1 ORDER BY RAND() LIMIT 5");$query3=mysqli_query($dbconnect,"SELECT companyname,client_id,feedback,status from review WHERE status=3");$rows_get = mysqli_num_rows($query);如果($rows_get > 0){{$row1 = mysqli_fetch_assoc($query);$row2 = mysqli_fetch_assoc($query3);$row3 = mysqli_fetch_assoc($query3);$row4 = mysqli_fetch_assoc($query3);$row5 = mysqli_fetch_assoc($query3);}}else if ($rows_get >1) {{$row1 = mysqli_fetch_assoc($query);$row2 = mysqli_fetch_assoc($query);$row3 = mysqli_fetch_assoc($query3);$row4 = mysqli_fetch_assoc($query3);$row5 = mysqli_fetch_assoc($query3);}}else if ($rows_get >2) {{$row1 = mysqli_fetch_assoc($query);$row2 = mysqli_fetch_assoc($query);$row3 = mysqli_fetch_assoc($query);$row4 = mysqli_fetch_assoc($query3);$row5 = mysqli_fetch_assoc($query3);}}else if ($rows_get >3) {{$row1 = mysqli_fetch_assoc($query);$row2 = mysqli_fetch_assoc($query);$row3 = mysqli_fetch_assoc($query);$row4 = mysqli_fetch_assoc($query);$row5 = mysqli_fetch_assoc($query3);}}else if ($rows_get >4) {{$row1 = mysqli_fetch_assoc($query);$row2 = mysqli_fetch_assoc($query);$row3 = mysqli_fetch_assoc($query);$row4 = mysqli_fetch_assoc($query);$row5 = mysqli_fetch_assoc($query);}}别的 {$row1 = mysqli_fetch_assoc($query3);$row2 = mysqli_fetch_assoc($query3);$row3 = mysqli_fetch_assoc($query3);$row4 = mysqli_fetch_assoc($query3);$row5 = mysqli_fetch_assoc($query3);}

这是帖子被拉到的 php/html 方面，这是我遇到问题的地方

 
<p class="mb-0">"<?php echo $row1['feedback']; ?>"</p><footer class="blockquote-footer"><?php echo $row1['client_id'];?>@ <?php echo $row1['companyname'];?></footer></blockquote><blockquote class="blockquote-reverse"><p class="mb-0">"<?php echo $row2['feedback']; ?>"</p><footer class="blockquote-footer"><?php echo $row2['client_id'];?>@ <?php echo $row2['companyname'];?></footer></blockquote><blockquote class="blockquote"><p class="mb-0">"<?php echo $row3['feedback']; ?>"</p><footer class="blockquote-footer"><?php echo $row3['client_id'];?>@ <?php echo $row['companyname'];?></footer></blockquote><blockquote class="blockquote-reverse"><p class="mb-0">"<?php echo $row4['feedback']; ?>"</p><footer class="blockquote-footer"><?php echo $row4['client_id'];?>@ <?php echo $row4['companyname'];?></footer></blockquote><blockquote class="blockquote"><p class="mb-0">"<?php echo $row5['feedback']; ?>"</p><footer class="blockquote-footer"><?php echo $row5['client_id'];?>@ <?php echo $row5['companyname'];?></footer></blockquote>

解决方案

这可能是您问题的解决方案，即使它有点棘手:

if ($dbconnect->connect_error) {die("数据库连接失败:" . $dbconnect->connect_error);}$query=mysqli_query($dbconnect,"SELECT DISTINCT companyname,client_id,feedback,status from review WHERE status=1 ORDER BY RAND() LIMIT 5");$query3=mysqli_query($dbconnect,"SELECT companyname,client_id,feedback,status from review WHERE status=3");$rows_get = mysqli_num_rows($query);$nq=0;while($row=mysqli_fetch_array($query,MYSQLI_ASSOC)){如果 ($rows_get == 1 && $nq < 1) {回声 $row['公司名称'];回声 $row['client_id'];回声 $row['反馈'];回声 $row['status'];++$nq;} else if ($rows_get == 2 && $nq < 2) {回声 $row['公司名称'];回声 $row['client_id'];回声 $row['反馈'];回声 $row['status'];++$nq;} else if ($rows_get == 3 && $nq < 3) {回声 $row['公司名称'];回声 $row['client_id'];回声 $row['反馈'];回声 $row['status'];++$nq;} else if ($rows_get == 4 && $nq < 4) {回声 $row['公司名称'];回声 $row['client_id'];回声 $row['反馈'];回声 $row['status'];++$nq;} else if ($rows_get == 5 && $nq < 5) {回声 $row['公司名称'];回声 $row['client_id'];回声 $row['反馈'];回声 $row['status'];++$nq;} 别的 {休息;}}$nq=0;while($row3=mysqli_fetch_array($query3,MYSQLI_ASSOC)){如果 ($rows_get == 0 && $nq < 5) {回声 $row3['公司名称'];回声 $row3['client_id'];回声 $row3['反馈'];echo $row3['status'];++$nq;} else if ($rows_get == 1 && $nq < 4) {回声 $row3['公司名称'];回声 $row3['client_id'];回声 $row3['反馈'];echo $row3['status'];++$nq;} else if ($rows_get == 2 && $nq < 3) {回声 $row3['公司名称'];回声 $row3['client_id'];回声 $row3['反馈'];echo $row3['status'];++$nq;} else if ($rows_get == 3 && $nq < 2) {回声 $row3['公司名称'];回声 $row3['client_id'];回声 $row3['反馈'];echo $row3['status'];++$nq;} else if ($rows_get == 4 && $nq < 1) {回声 $row3['公司名称'];回声 $row3['client_id'];回声 $row3['反馈'];echo $row3['status'];++$nq;} 别的 {休息;}}

I'm trying to do a if else depending on the rows that it get back but its not working right i dont know what i'm doing wrong if anyone can give me some insite on what i'm doing wrong would be so much of a help thank you in advance

$dbconnect=mysqli_connect($hostname,$username,$password,$db);

if ($dbconnect->connect_error) {
  die("Database connection failed: " . $dbconnect->connect_error);
}
$query=mysqli_query($dbconnect,"SELECT DISTINCT companyname,client_id,feedback,status from review WHERE status=1 ORDER BY RAND() LIMIT 5");
$query3=mysqli_query($dbconnect,"SELECT companyname,client_id,feedback,status from review WHERE status=3");
$rows_get = mysqli_num_rows($query);

if ($rows_get >0) {
{
   $row1 = mysqli_fetch_assoc($query);
   $row2 = mysqli_fetch_assoc($query3);
   $row3 = mysqli_fetch_assoc($query3);
   $row4 = mysqli_fetch_assoc($query3);
   $row5 = mysqli_fetch_assoc($query3);
}
}else if ($rows_get >1) {
{
   $row1 = mysqli_fetch_assoc($query);
   $row2 = mysqli_fetch_assoc($query);
   $row3 = mysqli_fetch_assoc($query3);
   $row4 = mysqli_fetch_assoc($query3);
   $row5 = mysqli_fetch_assoc($query3);
}
}else if ($rows_get >2) {
{
   $row1 = mysqli_fetch_assoc($query);
   $row2 = mysqli_fetch_assoc($query);
   $row3 = mysqli_fetch_assoc($query);
   $row4 = mysqli_fetch_assoc($query3);
   $row5 = mysqli_fetch_assoc($query3);
} 
}else if ($rows_get >3) {
{
   $row1 = mysqli_fetch_assoc($query);
   $row2 = mysqli_fetch_assoc($query);
   $row3 = mysqli_fetch_assoc($query);
   $row4 = mysqli_fetch_assoc($query);
   $row5 = mysqli_fetch_assoc($query3);
}
}else if ($rows_get >4) {
{
   $row1 = mysqli_fetch_assoc($query);
   $row2 = mysqli_fetch_assoc($query);
   $row3 = mysqli_fetch_assoc($query);
   $row4 = mysqli_fetch_assoc($query);
   $row5 = mysqli_fetch_assoc($query);
} 
}else {
   $row1 = mysqli_fetch_assoc($query3);
   $row2 = mysqli_fetch_assoc($query3);
   $row3 = mysqli_fetch_assoc($query3);
   $row4 = mysqli_fetch_assoc($query3);
   $row5 = mysqli_fetch_assoc($query3);
}

解决方案

This is could be a solution for your problem, even if it's a bit tricky:

if ($dbconnect->connect_error) {
  die("Database connection failed: " . $dbconnect->connect_error);
}
$query=mysqli_query($dbconnect,"SELECT DISTINCT companyname,client_id,feedback,status from review WHERE status=1 ORDER BY RAND() LIMIT 5");
$query3=mysqli_query($dbconnect,"SELECT companyname,client_id,feedback,status from review WHERE status=3");
$rows_get = mysqli_num_rows($query);

$nq=0;

while($row=mysqli_fetch_array($query,MYSQLI_ASSOC))
{
    if ($rows_get == 1 && $nq < 1) {
        echo $row['companyname'];
        echo $row['client_id'];
        echo $row['feedback'];
        echo $row['status'];
        ++$nq;
    } else if ($rows_get == 2 && $nq < 2) {
        echo $row['companyname'];
        echo $row['client_id'];
        echo $row['feedback'];
        echo $row['status'];
        ++$nq;
    } else if ($rows_get == 3 && $nq < 3) {
        echo $row['companyname'];
        echo $row['client_id'];
        echo $row['feedback'];
        echo $row['status'];
        ++$nq;
    } else if ($rows_get == 4 && $nq < 4) {
        echo $row['companyname'];
        echo $row['client_id'];
        echo $row['feedback'];
        echo $row['status'];
        ++$nq;
    } else if ($rows_get == 5 && $nq < 5) {
        echo $row['companyname'];
        echo $row['client_id'];
        echo $row['feedback'];
        echo $row['status'];
        ++$nq;
    } else {
       break;
    }
}

$nq=0;

while($row3=mysqli_fetch_array($query3,MYSQLI_ASSOC))
{
    if ($rows_get == 0 && $nq < 5) {
        echo $row3['companyname'];
        echo $row3['client_id'];
        echo $row3['feedback'];
        echo $row3['status'];
        ++$nq;
    } else if ($rows_get == 1 && $nq < 4) {
        echo $row3['companyname'];
        echo $row3['client_id'];
        echo $row3['feedback'];
        echo $row3['status'];
        ++$nq;
    } else if ($rows_get == 2 && $nq < 3) {
        echo $row3['companyname'];
        echo $row3['client_id'];
        echo $row3['feedback'];
        echo $row3['status'];
        ++$nq;
    } else if ($rows_get == 3 && $nq < 2) {
        echo $row3['companyname'];
        echo $row3['client_id'];
        echo $row3['feedback'];
        echo $row3['status'];
        ++$nq;
    } else if ($rows_get == 4 && $nq < 1) {
        echo $row3['companyname'];
        echo $row3['client_id'];
        echo $row3['feedback'];
        echo $row3['status'];
        ++$nq;
