如何使用mysql行结果作为get_file_content变量包含文件名？

Question

Anyone to help me find what's wrong with this script? When this php file is ajax called via a defined ID, it change content of a whole with the result from the DB, but my problem is to get the result from $row['urlOfInclude'] and use it as an include filename in this context :

function get_file_content($filename) {
        if (is_file($filename)) {
            ob_start();
            include $filename;
            return ob_get_clean();
        } else {
            ob_clean();
            trigger_error("The file {$filename} is not available");
        }
    }

    $rajo get_file_content("$row['url']");

    echo "<tr>";
      echo "<td>" $rajo "</td>";
      echo "</tr>";

Here is the full code of the php file (rajo.php) which echo result from mysql (while I'm using another ajax code in the html page to show the echo result):

 <?php
    $q = intval($_GET['q']);

    $con = mysqli_connect('localhost','dbuser','dbpass','dbname');
    if (!$con)
      {
      die('Could not connect: ' . mysqli_error($con));
      }

    mysqli_select_db($con,"dbname");
    $sql="SELECT * FROM tablename WHERE id = '".$q."'";

    $result = mysqli_query($con,$sql);


    echo "<table border='0'>
    <tr>
    <th class='02'>ID</th>
    <th class='01'> Nom of the Station</th>
    <th class='03'> FM MHz </th>
    <th class='03'> Telephone Number </th>
    <th class='03'>Skype ID </th>
    <th class='03'> WebSite </th>
    </tr>";

    while($row = mysqli_fetch_array($result))
      {
      echo "<tr>";
      echo "<td>" . $row['id'] . "</td>";
      echo "<td>" . $row['nameOfTheStation'] . "</td>";
      echo "<td>" . $row['fmmhz'] . "</td>";
      echo "<td>" . $row['telephoneNumber'] . "</td>";
      echo "<td>" . $row['skypeID'] . "</td>";
      echo "<td>" . $row['urlOfInclude'] . "</td>";
      echo "</tr>";
      }

    function get_file_content($filename) {
        if (is_file($filename)) {
            ob_start();
            include $filename;
            return ob_get_clean();
        } else {
            ob_clean();
            trigger_error("The file {$filename} is not available");
        }
    }

    $rajo get_file_content("$row['url']");

    echo "<tr>";
      echo "<td>" $rajo "</td>";
      echo "</tr>";


    echo "</table>";


    mysqli_close($con);
    ?>

Or this rajo.php:

        return mysqli_query($connection, $sqlQuery);

    function displayDatabaseSuff($result)

NB: The last code was provided to me by Aretecode Here is the error I got when I run the the last code: Warning: file_get_contents() expects parameter 1 to be string, resource given in /home/user/public_html/folder/filename.php on line 63. Here is the php code on that line "$contents = file_get_contents($handler);" Here is the DB table:

Any help would be greatly appreciated...

Answer 1

You have this in your code:

$rajo get_file_content("$row['url']");

Shouldn't it be like this:

$rajo = get_file_content("$row['url']");
