PHP : Function Reference : PDO Functions : PDOStatement->fetchColumn()

PDOStatement->fetchColumn()

Returns a single column from the next row of a result set ()

Example 1789. 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:
