Issue with uploading file inputs with multiple names - php

Question

I have several file input fields with a common name and a unique name for each file input .The unique name is for some validation purposes.
<input name="file12 ftr_file_uploads[]" class="multi_files file " type="file">
<input name="file10 ftr_file_uploads[]" class="multi_files file " type="file">
<input name="file10 ftr_file_uploads[]" class="multi_files file " type="file">
...............
When trying to upload files in PHP form submit,
the content of $_FILES is as following.
array(2) {
["file1_ftr_file_uploads"]=> array(5)
{ ["name"]=> array(1) { [0]=> string(13) "Jellyfish.jpg" }
["type"]=> array(1) { [0]=> string(10) "image/jpeg" }
["tmp_name"]=> array(1) { [0]=> string(14) "/tmp/phpx7iId2" }
["error"]=> array(1) { [0]=> int(0) }
["size"]=> array(1) { [0]=> int(775702) } }
["file2_ftr_file_uploads"]=> array(5)
{ ["name"]=> array(1) { [0]=> string(12) "Penguins.jpg" }
["type"]=> array(1) { [0]=> string(10) "image/jpeg" }
["tmp_name"]=> array(1) { [0]=> string(14) "/tmp/phpN6QWoD" }
["error"]=> array(1) { [0]=> int(0) }
["size"]=> array(1) { [0]=> int(777835) } }
}
The array key name changed to the concatenated names of the file input field.I need the names to be ftr_file_uploads rather than fileIDnumber_ftr_file_uploads.
I have done like the following.
foreach($_FILES as $keyval=>$value)
{
$_FILES['ftr_file_uploads'] = $_FILES[$keyval]; //removed
$_FILES['ftr_file_uploads'][] mentioned in the answer
unset($_FILES[$keyval]);
}
When i am using like this,I am getting the result like this.
array(1) {
["ftr_file_uploads"]=>
array(5) {
["name"]=>
array(1) {
[0]=>
string(14) "Lighthouse.jpg"
}
["type"]=>
array(1) {
[0]=>
string(10) "image/jpeg"
}
["tmp_name"]=>
array(1) {
[0]=>
string(14) "/tmp/phpLdslxb"
}
["error"]=>
array(1) {
[0]=>
int(0)
}
["size"]=>
array(1) {
[0]=>
int(561276)
}
}
}

foreach ($_FILES as $name => $file) {
$_FILES['ftr_file_uploads'][] = $file; // [] means add $file to $_FILES['ftr_file_uploads'] array
unset($_FILES[$name]); // remove element from $_FILES
}
