PDOSTATEMENT.FETCHCOLUMN(3)						 1					       PDOSTATEMENT.FETCHCOLUMN(3)

PDOStatement::fetchColumn - Returns a single column from the next row of a result set

SYNOPSIS
public mixed PDOStatement::fetchColumn ([int $column_number]) DESCRIPTION
Returns a single column from the next row of a result set or FALSE if there are no more rows. Note PDOStatement.fetchColumn(3) should not be used to retrieve boolean columns, as it is impossible to distinguish a value of FALSE from there being no more rows to retrieve. Use PDOStatement.fetch(3) instead. PARAMETERS
o $column_number - 0-indexed number of the column you wish to retrieve from the row. If no value is supplied, PDOStatement.fetchColumn(3) fetches the first column. RETURN VALUES
PDOStatement.fetchColumn(3) returns a single column in the next row of a result set. Warning There is no way to return another column from the same row if you use PDOStatement.fetchColumn(3) to retrieve data. EXAMPLES
Example #1 Return first column of the next row <?php $sth = $dbh->prepare("SELECT name, colour FROM fruit"); $sth->execute(); print("Fetch the first column from the first row in the result set: "); $result = $sth->fetchColumn(); print("name = $result "); print("Fetch the second column from the second row in the result set: "); $result = $sth->fetchColumn(1); print("colour = $result "); ?> The above example will output: Fetch the first column from the first row in the result set: name = lemon Fetch the second column from the second row in the result set: colour = red SEE ALSO
