Print array key value

Question

I have an array which i get like this:

$tet = $SimplicateApi->makeApiCall('GET','/crm/person?q[first_name]=Kevin1');

I wanted to see all the array keys inside the array so i did

print_r(array_keys($tet['data']['0']));

The Results:

Array ( [0] => id [1] => interests [2] => simplicate_url [3] => avatar [4] => linked_as_contact_to_organization [5] => gender [6] => first_name [7] => family_name [8] => full_name [9] => email [10] => phone )

My question is how do i check whats inside in for example first_name

Check the edit for your question. You can see that there is not first_name [7]. You array has they key 6 and it's value is first_name (7 is the family_name). — Dekel

@Kevin.a, this is the way to access an array item at index zero. In this case $tet['data'] is the array. — Ruslan Osmanov

array_keys($array) returns an array of $array keys.

Since the result of array_keys($tet['data']['0']) contains first_name, we can access the value with the [] operator as follows:

print_r($tet['data']['0']['first_name']);

In this code we access $tet['data']['0'] array by 'first_name' key.

var_dump full array and see all keys and their values in one shot:

echo '<pre>'; var_dump($tet['data']['0']); echo '</pre>';

To have more insight, var_dump original array to get full info about it:

echo '<pre>'; var_dump($tet); echo '</pre>';

So that you may know why you have to use data key and the 0 key. <pre> tag is just used to have nice output.

I hope it helps
