PHP While-选择html标记

Question

I have an issue, I just cannot solve. I have a PHP script, which loops my membership packages from my database. I have now 5 membership packages, to 3 different memberships.

I want a SELECT option. So users can select what package they want, to each membership.

But when I tries to do a while loop, and loop it out, it just loops out ALL 5 membership packages. I want 3 SELECTs, with the membership package details inside.

My current code:

                                <?php
                                $p=mysql_query("SELECT * FROM membership_packages");
                                while($mp = mysql_fetch_assoc($p)):
                                    echo '      <select>
                                                <option>'.$mp['duration'].' Days</option>
                                                 </select>
                                          ';

                                endwhile;
                            ?>

<label for="c1">Selcciona la clave:</label>
        <select>
        <?php 
            $i=0;
            $var="10-";
            while ( $i<= 100) {
                echo $var." $i <option>";
                $i = $i + 1;
            }
        ?>

Either do the limit as someone else suggested or (if you want the logic only way of doing it, eg you dont know mysql) you can use and a iteration counter to stop the while loop something like:

i = 0 ;
while($mp = mysql_fetch_assoc($p) && i <=2):

echo '      <select>
<option>'.$mp['duration'].' Days</option>
</select>
  ';
 i++;

endwhile;

Edit: went to 4 not 3.

Answer 3

In addition to NoviceCoding's solution, you most definitely want to pull the opening and closing select tags out of the while loop. You only want those once but multiple option inside.

i = 0 ;
echo '<select>';
while($mp = mysql_fetch_assoc($p) && i <3):
    echo '<option>'.$mp['duration'].' Days</option>';
    i++;
endwhile;
echo '</select>';
