PDOStatement {
string fetchColumn(int column_number);
}
Returns a single column from the next row of a result set or FALSE
if
there are no more rows.
0-indexed number of the column you wish to retrieve from the row. If no value is supplied, PDOStatement->fetchColumn() fetches the first column.
PDOStatement->fetchColumn() returns a single column in the next row of a result set.
There is no way to return another column from the same row if you use PDOStatement->fetchColumn() to retrieve data.
<?php
$sth = $dbh->prepare("SELECT name, colour FROM fruit");
$sth->execute();
/* Fetch the first column from the next row in the result set */
print("Fetch the first column from the next row in the result set:\n");
$result = $sth->fetchColumn();
print("name = $result\n");
print("Fetch the second column from the next row in the result set:\n");
$result = $sth->fetchColumn(1);
print("colour = $result\n");
?>
The above example will output:
Fetch the first column from the next row in the result set:
name = lemon
Fetch the second column from the next row in the result set:
colour = red
