Last character removed

Posted on 16th Feb 2014 by admin

I have created a string from an array. I have inserted commas from my form values. I am trying to remove the last comma from the string and can't seem to remove it. I have tried chop, rtrim, substr, substr_remove, trim and none of them seem to remove the last comma. $sql_meeting2 = "SELECT * FROM meeting WHERE location_id = '$location_id' ORDER BY day_id";
$result_meeting2 = mysql_query($sql_meeting2) or die(mysql_error());
while($data_meeting2 = mysql_fetch_array($result_meeting2)){
$day = $data_meeting2['day'];
$times = $data_meeting2['time'];
$open = $data_meeting2['open'];
$format = $data_meeting2['format'];
$format is the string I am trying to rtrim from.
This is my form codeCode: <td style="padding-left:15px;">
<input type="checkbox" name="format[]" value="Discussion,">Discussion<br />
<input type="checkbox" name="format[]" value="Basic Text Study,">Basic Text Study<br />
<input type="checkbox" name="format[]" value="It Works Study,">It Works Study<br />
<input type="checkbox" name="format[]" value="IP Study,">IP Study<br />
<input type="checkbox" name="format[]" value="Topic,">Topic<br />
<input type="checkbox" name="format[]" value="Candlelight,">Candlelight<br />
<input type="checkbox" name="format[]" value="Speaker,">Speaker<br />
<input type="checkbox" name="format[]" value="Birthday,">Birthday<br />
<input type="checkbox" name="format[]" value="Men,">Men<br />
<input type="checkbox" name="format[]" value="Women,">Women<br />
<input type="checkbox" name="format[]" value="Varies,">Varies<br />
<input type="checkbox" name="format[]" value="Other">Other
</td></tr>I have manipulated this form information with this:
$formats = $_POST['format'];
$format = implode(' ',$formats);
Can anyone help?
