How can I define the last element in a foreach loop? - php

Question

This is my for each loop
foreach ($row as $key => $value) {
echo $key;
}
The result is:
one
four
end
three
two
I want now that the $key end is always at the end. Is this possible?
Something like
foreach ($row as $key => $value) {
if($key == "end"){
echo $key as last;
} else {
echo $key;
}
}
So that the result is
one
four
three
two
end

Answer 1

As mentined in my comment, simply add the static value to the end of your array
array_push($row, "end");

Answer 2

If you want you can create a custom function , pass your array to a function. Inside that function you could filter the data the way you want .I have created formatRow() function , it just remove the key that you want at last from the array , and insert it again , as the new value are always inserted at end of array , you get the desired output
$row = array(
'one'=>"data",
'four'=>"data",
'end'=>"enddata",
'three'=>"data",
'two'=>"data",
);
$formatted_row = formatRow($row,'end');
echo "<pre>";
var_dump($formatted_row);
//output
// array(5) {
// ["one"]=>
// string(4) "data"
// ["four"]=>
// string(4) "data"
// ["three"]=>
// string(4) "data"
// ["two"]=>
// string(4) "data"
// ["end"]=>
// string(7) "enddata"
// }
function formatRow ($row,$key_that_you_need_last) {
if (array_key_exists($key_that_you_need_last,$row)) {
$value = $row["$key_that_you_need_last"];
unset($row["$key_that_you_need_last"]);
$row["$key_that_you_need_last"] = $value;
}
return $row;
}
