I want to merge that array into one array. My question is how to merge that array the output must be like this
array(
[0]=>array(
[0]=>AED
[1]=>1
[2]=>4071.64
[3]=>3603.98
)
[1]=>array(
[0]=>AUD
[1]=>1
[2]=>10151.11
[3]=>9964.65
)
[3]=>array(
[0]=>CHF
[1]=>1
[2]=>14162.66
[3]=>13912.70
)
//and so on
)
OR the result like this

Please help me, brothers and sisters, I have tried using array_merge() and array_push() but not showing the right result. Thanks

You can use array_chunk for that if it's always inner arrays of length == 4.
$text = "AED 1 4071.64 3603.98 AUD 1 10151.11 9964.65";
$result= array_chunk( explode( ' ', $text ), 4 );
var_dump( $result );
Here's a php sandbox link.

Try this code:
$array_data = array(
array(
AED, 1, 4071.64, 3603.98
),
array(
AUD, 1, 10151.11, 9964.65
),
array(
CHF, 1, 14162.66, 13912.70
),
);
$a = [];
foreach($array_data as $data) {
$a = array_merge($a, $data);
}

echo multidimensional array values into a readable format

If you want this for debugging then output like this:
echo '<pre>';
print_r($visits);
echo '</pre>';
Other ways use array_walk_recursive()

You can use array_walk_recursive() to loop through each value of your array, e.g.
array_walk_recursive($visits, function($v, $k){
echo $v . "<br>";
});

Recursively remove elements from nested array looking for a specific value

One problem with your code is that sizeof($locations) changes every time you do a unset. So whenever you have two consecutive [$n][1] having "0,0", you are not able to detect that. Also your code is not looking at just[$n][1], its looking at all indexes in [$n][]
Use the below code:
$count = count($locations);
for ($i = 0; $i < $count; $i++) {
if ($locations[$i][1] == "0,0") {
unset($locations[$index]);
}
}
$locations = array_values($locations);

foreach ($locations as $index => $row) {
if ($locations[$index][1] == "0,0") unset($locations[$index]);
}
$locations = array_values($locations);

php array_unique bug in 2d ARRAY

By default array_unique compares the items as if they are string, which means that it actually converts the arrays to string (and any array casted to string will be the same - the string 'Array'). So you have to do:
$a = array_unique($a, SORT_REGULAR)
