i am trying to get array values to string, but i fail

My array ($epg) looks like this:

Array
(
)
Array
(
    [0] => Array
        (
            [title] => VGhlIEZhbnRhc3kgRm9vdGJhbGwgQ2x1Yg==
            [lang] => en
            [start] => 1425385800
            [end] => 1425387600
            [description] => Sm9obiBGZW5kbGV5IGFuZCBQYXVsIE1lcnNvbiBwcmVzZW50IGEgZGlzY3Vzc2lvbiBvbiBrZXkgZmFudGFzeSBmb290YmFsbCBpc3N1ZXMsIGFzIHdlbGwgYXMgdGhlIHdlZWtlbmQncyBQcmVtaWVyIExlYWd1ZSBtYXRjaGVzLiBBbHNvIGZlYXR1cmluZyBndWVzdHMgZnJvbSB0aGUgd29ybGRzIG9mIHNwb3J0IGFuZCBzaG93Yml6Lg==
        )

    [1] => Array
        (
            [title] => QmFyY2xheXMgUHJlbWllciBMZWFndWUgUmV2aWV3
            [lang] => en
            [start] => 1425387600
            [end] => 1425391200
            [description] => QSBsb29rIGJhY2sgYXQgcmVjZW50IGZpeHR1cmVzIGluIHRoZSBFbmdsaXNoIFByZW1pZXIgTGVhZ3VlLCBhcyB0aGUgc2Vhc29uIGNvbnRpbnVlZCB3aXRoIG1hdGNoZXMgYWZmZWN0aW5nIGJvdGggZW5kcyBvZiB0aGUgdGFibGUu
        )

)
Array
(
)

And then i create foreach loop, and try to get values like this:

$title = $epg['title'];
$lang = $epg['lang'];
echo $lang;
echo $title;

But i get errors:

Notice: Undefined index: title in........ Notice: Undefined index: lang in.........

I am guessing that happens, because i have strange array , these empty arrays at start and end.

If so, how can i fix it?

When you define the array like here

[0] => Array
    (
        [title] => VGhlIEZhbnRhc3kgRm9vdGJhbGwgQ2x1Yg==
        [lang] => en
        [start] => 1425385800
        [end] => 1425387600
        [description] => Sm9obiBGZW5k...
    )

If you don't have title, lang, etc. delcared as variables you need to have

[0] => Array
    (
        ['title'] => VGhlIEZhbnRhc3kgRm9vdGJhbGwgQ2x1Yg==
        ['lang'] => en
        ['start'] => 1425385800
        ['end'] => 1425387600
        ['description'] => Sm9obiBGZW5k...
    )

Use this remove ur empty and then use this

print_r(array_filter($epg));

echo $title = $epg['title']

Check if your array is not empty

if (count($epg) != 0)

You get notices, not errors. But it is good practice to treat them as errors and removing from Your code.

These notices are about undefined indexes, so You have to check if given index is present in current element of array. You can do it like this:

$title = array_key_exists('title',$epg) ? $epg['title'] : NULL;
