After several hours of messing, sweating and pulling my hair out I'm still unable to access these values. I want to loop through the first level of arrays, and that's simple enough with a basic 'foreach' loop but I can't seem to get to the '['suitability']' array on the second sub array. I've looked around but can't seem to get anything other than really basic array tutorials which don't seem to delve to far into looping.

I'm trying to access the values in the nested/sub array ie '['Species_name']'.

I don't want to use associative keys as the sorting is a bit of an issue.

Array
(
    [0] => Array
        (
            [id] => 1
            [name] => Bradeley Hall Pool
            [postcode] => CW1 5QN
            [lat] => 53.10213
            [lon] => -2.41069
            [size] => 1.60
            [pegs] => 21
            [distance] => 26.6
        )

    [1] => Array
        (
            [id] => 2
            [name] => Farm Pool
            [postcode] => CW9 6JQ
            [lat] => 53.320502
            [lon] => -2.549049
            [size] => 0.88
            [pegs] => 8
            [distance] => 15.4
            [suitability] => Array
                (
                    [0] => Array
                        (
                            [fk_water_id] => 2
                            [fk_species_id] => 4
                            [species_name] => Barbel
                            [species_rating] => 1
                            [record_id] => 1
                            [weight_kg] => 2.721554
                            [length_cm] => 40
                            [height_cm] => 30
                        )
                )
       )
)

what do you mean when you say "I don't want to use associative keys as the sorting is a bit of an issue." –  Orangepill Jun 17 '13 at 2:02

The thing that is probably tripping you up is that suitability is an array of arrays not just an array so in an example where you want to get the species_name property of the first second top level element you would use something like 

$array[1]["suitability"][0]["species_name"];

It's worth noting that your first array does not contain a "suitability" value so that would not be able to be accessed. In a foreach loop you could use a construct similar to this:

foreach($array as $value){
     if (isset($value["suitability"]){
            echo $value["suitability"][0]["species_name"];
     }
}

You may take a look at PHP: RecursiveArrayIterator class

This allow you to iterate over multiples nested ArrayIterator. If you're not using any ArrayIterator, then you should consider to try them.
