将数组值显示为数组中的数字

Currently my code shows the year from 1885 to 2017. What this does is show the years like so 0 = 1885, 1 = 1886.

What I want is that it shows it like this 1885 = 1885, 1886 = 1886 etc. (This resembles the date a car is built)

$options = [];
for ($x = 1885; $x <= date("Y"); $x++) {
array_push($options, $x);
}

  echo $this->Form->select('year', [
       $options,
   ],[
     'label' => false,
     'class' => 'form-group form-control',
   ]);

So I was wondering how to fix what I did wrong.

for ($x = 1885; $x <= date("Y"); $x++) {
    $options[$x] = $x;
}

You need to set the keys of the $options array as the keys are used as values to be submitted. You can as well benefit from using the range function to generate the array:

$values = array_map('strval', range(1885, (int) date("Y")));
$options = array_combine($values, $values);

You can also do this using range() and array_combine():-

$years = range(1985, date('Y'));
$options = array_combine($years, $years);
