This code exports data into a csv file, which is opened within Excel.

When a string has a comma within it, it messes up the order of the data.

I need help modifying my code below to resolve any data that contains a comma within it, to not to create a new column.

I am assuming it will pass each string within double quotes, so any comma within those quotes, then it will make an exception.

Any help is appreciated.

$result = mysql_query("select lname, fname, email, dtelephone, etelephone, contactwhen, comments, thursday, 
friday, saturday, sunday, monday FROM volunteers_2010");

$csv_output .= "Last Name,First Name,Email,Telephone (Day),Telephone (Evening),Contact When,Comments,Thursday,Friday,Saturday,Sunday,Monday,Comments\n";

$i = 0;
if (mysql_num_rows($result) > 0) {
 while ($row = mysql_fetch_assoc($result)) {
  $csv_output .= $row['Field'].", ";
  $i++;
 }
}
$csv_output .= "\n";

$values = mysql_query("SELECT lname, fname, email, dtelephone, etelephone, contactwhen, comments, thursday, 
friday, saturday, sunday, monday FROM volunteers_2010 WHERE venue_id = $venue_id");

while ($rowr = mysql_fetch_row($values)) {
 for ($j=0;$j<$i;$j++) {
  $csv_output .= $rowr[$j].", ";
 }
 $csv_output .= "\n";
}
