php - Calculate percentage of up votes for each record. -

i have searched site , google , can't figure out

<?php  $artistname = "select * voting"; $artistnameresults = mysql_query( $artistname ) or die( "could not video games " .mysql_error() );  for( $i = 0; $i < mysql_numrows( $artistnameresults ); $i++ ) {     $data = mysql_fetch_array( $artistnameresults );     echo "<div>". $data['artist'] ." has " . $data['votes'] ." votes</div>\n"; }      ?> 

how echo out percentage of total votes each record table?

so first total votes in variable, in next check if total votes more 0 avoid error.

$num_rows = mysql_numrows($artistnameresults); $total_votes = 0; $rows = array(); for( $i = 0; $i < $num_rows; $i++ ) {     $data = mysql_fetch_array( $artistnameresults );     $total_votes += $data['votes'];     $row[] = $data; }  foreach($rows $data) {     echo "<div>". $data['artist'] ." has " . $data['votes'] ." votes ";     if($total_votes > 0)         $temp_votes = $data['votes']/$total_votes;       else         $temp_votes = 1;             echo '( '.($temp_votes*100).'%)';     echo "</div>\n"; }
