Question

stdClass Object
(
    [campaign-ID] => 1
    [campaign_name] => Sample Campaign
    [start_duration] => 2012-04-17
    [end_duration] => 2012-04-17
    [activity$] => 
    [survey_settings] => Ordering K-Cup Packs
    [$limit] => sample
    [$goal] => 
)

How to remove the – and $ ? using php?
Because - and $ sign is valid in mysql, but when I’ll try to display it using foreach, it wont work. So what should i do to remove that without editing the field names in the database table?

Answer 1

Am not sure where you got this class but there are so many invalid Naming here

Example

$goal campaign-ID etc.

I had to reconstruct your class and it looked like this

$st= new stdClass();
$st->{"campaign-ID"} = 1 ;
$st->campaign_name = "Sample Campaign" ;
$st->start_duration = "2012-04-17" ;
$st->start_duration = "2012-04-17" ;
$st->{'activity$'} = null ;
$st->survey_settings = "Ordering K-Cup Packs" ;
$st->{'$limit'}  = "sample" ;
$st->{'$goal'} = null ;


$std = new stdClass();
foreach($st as $key => $value)
{
    $key = str_replace(array('$',"-"),array('',"_"),$key);
    $std->{$key} = $value ;
}

echo "<pre>" ;
print_r($std);

Output

stdClass Object
(
    [campaign_ID] => 1
    [campaign_name] => Sample Campaign
    [start_duration] => 2012-04-17
    [activity] => 
    [survey_settings] => Ordering K-Cup Packs
    [limit] => sample
    [goal] => 
)

I’ll advice you create more valid variables name rather than such conversions
