Loops returning only one value from array - php

Question

I have the following array that I converted from a JSON response of the WP REST API:
Array
(
[0] => Array
(
[id] => 6
[convite_id] => Array
(
[0] => 4
)
[nome_do_convidado] => John Doe
[email_do_convidado] => Array
(
[0] => johndoe#gmail.com
)
)
[1] => Array
(
[id] => 5
[convite_id] => Array
(
[0] => 4
)
[nome_do_convidado] => Lorem
[email_do_convidado] => Array
(
[0] => lorem#gmail.com
)
)
)
And I'm trying to loop the [email_do_convidado] value as:
johndoe#gmail.com
lorem#gmail.com
I've tried with foreach() loop and just get the last one, and now I've tried with while() and get one result too, follow my script:
while (list ($key, $val) = each ($myArray) ) echo $val['email_do_convidado'][$key];
And the result is:
johndoe#gmail.com
What I'm doing wrong here?

Answer 1

Try with a foreach instead of a while. You can extract all the emails by merging all arrays into a final output.
$emails = [];
foreach($myArray as $entry){
$emails = array_merge($emails, $entry['email_do_convidado']);
}
var_dump($emails);
I assume you'll want to do something afterwards will all the emails. I'll leave that up to you.

Answer 2

Its not quite clear, what i understand is that u want the first email of each element, if thats the case u could do this
foreach($array as $value){
echo $value[email_do_convidado][0];
}
On the other hand if u have several emails inside "email_do_convidado" u could loop that other array
foreach($array as $value){
foreach($value[email_do_convidado] as $email){
echo $email;
}
}
Or if u dont want to use a foreach inside a foreach u can
//inside the first foreach.
$emails = implode(',', $value[email_do_convidado]);
//and the u echo $emails
echo $emails;
Hope my answer helps u.

The values you are seeking are in:
$myArray[0]['email_do_convidado'][0]
$myArray[1]['email_do_convidado'][0]
Your code is:
while (list ($key, $val) = each ($myArray) ) {
echo $val['email_do_convidado'][$key];
}
(slightly amended to better style)
So your code is trying to retrieve
$myArray[0]['email_do_convidado'][0]
$myArray[1]['email_do_convidado'][1]
The latter doesn't exist. So I'm afraid you have failed on multiple levels:
your code doesn't do what you intend
your error reporting is not working (PHP is throwing a warning about this you are not seeing)
you haven't attempted to instrument your code to see what's happening (simply putting "email=" before the value in your echo statement would have revealed this).
Try:
echo $val['email_do_convidado'][0];
