pdostatement.bindcolumn
PDOSTATEMENT.BINDCOLUMN(3) 1 PDOSTATEMENT.BINDCOLUMN(3)PDOStatement::bindColumn - Bind a column to a PHP variable
SYNOPSIS
public bool PDOStatement::bindColumn (mixed $column, mixed &$param, [int $type], [int $maxlen], [mixed $driverdata])
DESCRIPTION PDOStatement.bindColumn(3) arranges to have a particular variable bound to a given column in the result-set from a query. Each call to
PDOStatement.fetch(3) or PDOStatement.fetchAll(3) will update all the variables that are bound to columns.
Note
Since information about the columns is not always available to PDO until the statement is executed, portable applications should
call this function afterPDOStatement.execute(3).
However, to be able to bind a LOB column as a stream when using the PgSQL driver, applications should call this method before call-
ing PDOStatement.execute(3), otherwise the large object OID will be returned as an integer.
PARAMETERS
o $column
- Number of the column (1-indexed) or name of the column in the result set. If using the column name, be aware that the name
should match the case of the column, as returned by the driver.
o $param
- Name of the PHP variable to which the column will be bound.
o $type
- Data type of the parameter, specified by the PDO::PARAM_* constants.
o $maxlen
- A hint for pre-allocation.
o $driverdata
- Optional parameter(s) for the driver.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Binding result set output to PHP variables
Binding columns in the result set to PHP variables is an effective way to make the data contained in each row immediately available
to your application. The following example demonstrates how PDO allows you to bind and retrieve columns with a variety of options
and with intelligent defaults.
<?php
function readData($dbh) {
$sql = 'SELECT name, colour, calories FROM fruit';
try {
$stmt = $dbh->prepare($sql);
$stmt->execute();
/* Bind by column number */
$stmt->bindColumn(1, $name);
$stmt->bindColumn(2, $colour);
/* Bind by column name */
$stmt->bindColumn('calories', $cals);
while ($row = $stmt->fetch(PDO::FETCH_BOUND)) {
$data = $name . " " . $colour . " " . $cals . "
";
print $data;
}
}
catch (PDOException $e) {
print $e->getMessage();
}
}
readData($dbh);
?>
The above example will output:
apple red 150
banana yellow 175
kiwi green 75
orange orange 150
mango red 200
strawberry red 25
