Question

I’m working on a web application that takes its data from a web page using the Yahoo Query Language API to return a JSON array. I’ve hit a block in that sometimes, when there is only one “race” on the page, the array is setup differently and I can’t iterate through it in some circumstances. Let me explain in an example.

Array layout for a page with mutiple races

Array (
    [div] => array (
        [0] => array (
            ['venue_id'] = 02222
            ['venue_name'] = 'Hove'
            ['race_id'] = 9222
        )
        [1] => array (
            ['venue_id'] = 03333
            ['venue_name'] = 'Romford'
            ['race_id'] = 2442
        )
        //...and so on
    )
)

Array layout for a page with just one race

Array (
    [div] => array (
        ['venue_id'] = 02222
        ['venue_name'] = 'Hove'
        ['race_id'] = 9222
    )
)

In the application, I’m currently using a simple foreach statement to iterate through the array. However, this obviously wont work with the second example and I need a workaround.

Example of foreach statement

foreach($result['div'] as $race) {
    echo 'Venue ID: '.$race['venue_id'];
    echo 'Venue Name: '.$race['venue_name'];
    echo 'Race ID: '.$race['race_id'];
}

Any help would be massively appreciated!

Answer 1

I’d do this..

if(!isset($array[‘div’][0]))
$array[‘div’] = array($array[‘div’]);

This way I do not have to have two iteration methods.
