How can the position of a key in an array be determined in PHP?

To determine the position of a key in an array in PHP, you can use the array_search() function. This function searches an array for a specific value and returns the corresponding key if found. If the key is not found, it returns false. 

$array = array('a' => 1, 'b' => 2, 'c' => 3);
$key = 'b';
$position = array_search($key, array_keys($array));
if($position !== false){
    echo "The key '$key' is at position $position in the array.";
} else {
    echo "Key not found in the array.";
}
