Array in array for array_shift
I have several arrays from $ _REQUEST. For example: $ _REQUEST ['name'] and $ _REQUEST ['email']. That is, inside these arrays there is also an array. It turns out an array in an array.
Assigned them value
$name = $_REQUEST['name'];
$email = $_REQUEST['email'];
now I need to remove the first key with the value. For this I used array_shift
array_shift($name);
array_shift($email);
so i got rid of the first value. But, besides the name and email, there are others. It would not be desirable for everyone to write array_shift. How can I apply to all with one function?
thanx
UPD
For example $_REQUEST array:
Array (
[name] => Array (
[0] =>
[1] => myName
)
[email] => Array (
[0] =>
[1] => myEmail
)
[other] => Array (
[0] =>
[1] => otherDatas
)
)
I must get rid of these empty elements

Do you want to shift all arrays in$_REQUEST? Then you could just loop over them:foreach($_REQUEST as $r) array_shift($r);Or do you have a list/array of all variables that should be processed?

If I understand correctly, you have multiple arrays in your request and you want to do an array_shift on all of them?
You could loop through your $_REQUEST and apply that function to all the arrays. Maybe like this:
foreach ($_REQUEST as &$value) {
if (is_array($value) && empty($value[0])) {
array_shift($value);
}
}
That will shift all arrays in your request and leave any other variables alone.
EDIT: Updated the example to only shift arrays where the first element is empty.
EDIT2: Added & to $value so that you can change the $_REQUEST variable directly.

array_filter will clear empty values even if they are at any index.
$cleanArray = array();
foreach ($_REQUEST as $key => $value) {
$cleanArray[$key] = array_filter($value);
}
Output
Array (
[name] => Array (
[1] => myName
)
[email] => Array (
[1] => myEmail
)
[other] => Array (
[1] => otherDatas
)
)
Please note, it will also clear values like null, (blank) and false. Example Reference

print_r($result);
