<?php
      $sql="SELECT * FROM $tbl_name";
      $result=mysql_query($sql);

      // Count table rows
      $count=mysql_num_rows($result);

    while($rows=mysql_fetch_array($result)){

   $id[]=$rows['id'];
   echo $rows['id'];
     ?>

In the above above code, we have assigned values $id[]=$rows['id']; This will cause the error since we have not specified that the variable is an array before that statement.

so the solution is

// Count table rows
$count=mysql_num_rows($result);
$id = array();
?>

You have to declare a variable as an array before assigning values.

Happy coding

method ( &$var );

This can be avoided by replacing the above code with method ( $var )

You can also set allow_call_time_pass_reference to true in your php.ini it will go away. they are calling a function that was depreciated.If you don’t have access to modify php.ini file then, You can use a .htaccess file to set php.ini values …

php_value allow_call_time_pass_reference true.

Hope this helps,. Happy coding
