Returns a single column from the next row of a result set.
Parameters
column_number
0-indexed number of the column you wish to retrieve from the row. If
no value is supplied, PDOStatement::fetchColumn()
fetches the first column.
Return Values
PDOStatement::fetchColumn() 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() to retrieve data.
Examples
Example 1. Return first column of the next row
<?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
