how to capture returned values from php function parameter?

I am working with a wordpress plugin Gravity Forms.

The parameter $value var_dump result using gform_field_validation filter returns is this...

string(4) "2434"
string(8) "Fantasma"
string(8) "fantasma"
string(13) "buzzlightyear"
array(1) {
  ["11.1"]=>
  string(0) ""
}
array(1) {
  ["15.1"]=>
  string(1) "1"
}
string(2) "10"

I'm trying to capture the first string(4) "2434" but I have no idea how to target this.

Is there some php magic that can allow me to target this first string?

I know it's utter filth but Gravity Forms has left me choice to get this integer using their gform_field_validation filter.

Any ideas or thoughts would be much appreciated.

I think you will find that your output is the gform_field_validation being looped over all of the inputs.

If you are wanting to get the $value for a given field you will need to check the $field object to match what you are after such as this:

add_filter('gform_field_validation', function($result, $value, $form, $field) {
    if ($field->name == 'postcode') {
        return $value;
    }
});

This will then return the $value for the input named 'postcode' for example
