Question

The following array is output from my db.

$this->db->select('code')->from('table');
$array = $this->db->get()->result_array();

//Output:
Array ( [0] => Array ( [code] => ASDF123 ) [1] => Array ( [code] => ASDF124 ) )

How can I find if a variable is contained in this array?

ie.

if(this_is_in_array($value, $array) == TRUE)...

What’s the simplest way to to that with PHP?

I sincerely apologize for not wording this correctly the first time.

In case you wish to find the KEY of an array you would refer to the array_key_exists() method.
An example of this would be:

$array = array(
    'key1' => 'value1',
    'key2' => 'value2'
);

if ( array_key_exists( 'key2', $array ) )
    return TRUE;

If you would however prefer to find the VALUE of an array, you would refer to the in_array() method. An example of this would be:

$array = array(
    'key1' => 'value1',
    'key2' => 'value2'
);

if ( in_array( 'value1', $array ) )
    return TRUE;

Kevin:

foreach( $array as $key => $values )
{
    if ( $values['code'] == 'ASD1234' )
    {
        // do something
    }
}
