Question

Array (
[0] => Array ([username] => khaled [0] => khaled)
[1] => Array ([username] => Nariman [0] => Nariman)

)
I tried $posts['username'][0]/[0]['username'] ... didnt work!
I want to print out some values of the array, like the username for example. How to do it?

Answer 1

To get a single variable (so your username in your case), you do the following:
$username = $posts[0]['username'];
This will get the username from the first nested Array in your actual array. You can modify this to get every username from each nested array by making a for loop so you get the rest of the usernames.

Answer 2

You can use the following solution using foreach:
foreach ($arr as $arrItem) {
echo $arrItem['username'];
echo $arrItem[0];
}
You can also use a for loop:
for ($i = 0; $i < count($arr); $i++) {
echo $arr[$i]['username'];
echo $arr[$i][0];
}

Answer 3

On you array, key ['username'] does not exist.
If you indent the array, they read as this:
Array
[0]
[username] => khaled
[0] => khaled
[1]
[username] => Nariman
[0] => Nariman
...
Because this, you can read $posts[0][0] or $posts[0][username], but, you cant read $posts[username] because didn't exist.
