PHP: Get single value from complex array

Question

I have the following:

Array ( [0] => Array ( [0] => Array ( [value] => 150109 [format] => [safe_value] => 150109 ) ) )

I need to get the value "150109", but how on earth do I accomplish that?

Answer 1

Top level:

print_r($data);
// Output: Array ( [0] => Array ( [0] => Array ( [value] => 150109 [format] => [safe_value] => 150109 ) ) )

Outmost element:

print_r($data[0]);
// Output: Array ( [0] => Array ( [value] => 150109 [format] => [safe_value] => 150109 ) )

Next level:

print_r($data[0][0]);
// Output: Array ( [value] => 150109 [format] => [safe_value] => 150109 )

The final value

echo $data[0][0]['value'];
// Output: 150109

Accessing each layer of values this way makes it easier to figure out how to get to your desired value. After a while this becomes more obvious.
