Question

Is there a way to change the default functionality in Zend_Db fetchall() method, so that it doesn’t return this:

[0] => 100000055944231
[1] => 100000089064543
[2] => 100000145893011
[3] => 100000160760965

but this:

[100000055944231]
[100000089064543]
[100000145893011]
[100000160760965]

Answer 1

Although your question is actually flawed (noted by BartekR), I suppose you’re trying to receive a simple array, instead of a multidimensional one.

You could do:

$results = $this->db->fetchAll($select);
$values = array_map(function($row) { return $row['column']; }, $results);

This will turn:

array(
    array('column' => 'test'),
    array('column' => 'test2'),
    array('column' => 'test3'),
);

into

array(
    'test',
    'test2',
    'test3'
);

(note; my example only works in PHP5.3+, if you’re working with PHP5.2, you can define the function and use it by its name with array_map (e.g. array_map('methodName', $results))
