foreach ($arr as $key => $el).. Then echo the $key variable — Eddie

foreach ($arr as $key => $val) probably is what you are looking for. Or array_keys() php.net/manual/en/function.array-keys.php — arkascha

You can print key name like this:

$arr = ['night' => 'black', 'sun' => 'light', 'she' => 'gold'];

foreach ($arr  as $key => $el) {
    echo  $key. ' <br>';
}

Output:

night 
sun 
she

You should use:

<?php $array_keys = array_keys($your_array);

try this

$key contain all your array key and $value contain all your value

$arr = ['night' => 'black', 'sun' => 'light', 'she' => 'gold'];

foreach ($arr as $key=>$value) {
    echo $key."=".$value."<br>";
}
