html表php和echo

Question

The table headings appear on my web page, however the td's do not appear on my html page. I'm trying to echo the results of the while loop into the the table td. Can anyone please help?

 <table align= "centre" width="650" align="center">

  <tr> 
    <th> Post:id </th>
    <th> Title </th>
  </tr>


  <?php 
 include("includes.php"); 
 $get_posts = "select * from posts";
 $run_posts = mysql_query($get_posts);

while ($row_posts = mysql_fetch_array('$run_posts')) {

$post_id = $row_posts['post_id'];
$post_title = $row_posts['post_title'];

?> 

  <tr>   
    <td> <?php echo $post_id; ?> </td>
    <td> <?php echo $post_title; ?> /td>  
  </tr>

<?php } ?>  // CLOSE WHILE LOOP 
</table>

Answer 1

mysql_fetch_array('$run_posts')

is incorrect, you are passing the literal string '$run_posts', not the variable. Remove the single quotes:

mysql_fetch_array($run_posts)

Also, mysql_ functions are depreciated, use mysqli_ or PDO intead
