Why does this say undefined offset 2 in a foreach loop - php

Question

The $snippet variable has the following value:
Array
(
[0] => Array
(
[0] => Array
(
[id] => 1
[user_id] => 2
[title] => Title
[detail] => null
[lang_id] => 19
[edited] => false
[last_edited] =>
[created_date] => 2016-09-25 02:40:03
)
[1] => Array
(
[id] => 2
[user_id] => 2
[title] => Some other title
[detail] => null
[lang_id] => 19
[edited] => false
[last_edited] =>
[created_date] => 2016-09-25 02:40:03
)
[2] => Array
(
[id] => 3
[user_id] => 2
[title] => Huh!
[detail] => ...
[lang_id] => 19
[edited] => false
[last_edited] =>
[created_date] => 2016-09-25 03:04:48
)
)
[1] => Array
(
[0] => Array
(
[id] => 1
[user_id] => 2
[title] => Title
[detail] => null
[lang_id] => 19
[edited] => false
[last_edited] =>
[created_date] => 2016-09-25 02:40:03
)
[1] => Array
(
[id] => 2
[user_id] => 2
[title] => Some other title
[detail] => null
[lang_id] => 19
[edited] => false
[last_edited] =>
[created_date] => 2016-09-25 02:40:03
)
[2] => Array
(
[id] => 3
[user_id] => 2
[title] => Huh!
[detail] => ...
[lang_id] => 19
[edited] => false
[last_edited] =>
[created_date] => 2016-09-25 03:04:48
)
)
[2] => Array
(
[0] => Array
(
[id] => 4
[user_id] => 2
[title] => apache
[detail] => ...
[lang_id] => 1
[edited] => false
[last_edited] =>
[created_date] => 2016-09-25 03:05:06
)
)
)
I wanted my result to be something like:
Title
Some other title
Huh!
Title
Some other title
Huh!
apache
So I tried the following:
<?php foreach ($snippet as $key => $value): ?>
<?= $value[$key]['title'] ?>
<br />
<?php endforeach ?>
But the results were:
Title
Some other title
Notice: Undefined offset: 2
I can't figure out what I'm doing wrong.

Answer 1

Try this:
<?php
foreach ($snippet as $value):
foreach($value as $title):
echo $title['title']."<br>";
endforeach;
endforeach;
?>

Answer 2

Using the array_column() you can print your title's with the help of implode(). This is based on your try, cause you try with one foreach().
<?php
foreach ($snippet as $key => $value):
echo implode("<br/>", array_column($value[$key], 'title'));
endforeach;
?>
Just try this and let me know is it works or not.
