Embedding PHP in regular HTML
If you have been paying attention to our earlier
articles, you hopefully have picked up on how PHP
can be embedded into a regular HTML document. For
example, we should already know that the following
is an example of how PHP is embedded:

<html>
<head>
<title>My first PHP Page</title>
</head>
<body>
This is normal HTML code
<?php
// php code goes here
?>
Back into normal HTML
</body>
</html>

<?php
// database connection stuff here
if (!isset($screen))
$screen = 0;
$start = $screen * $rows_per_page;
$sql = "SELECT description FROM table_name ";
$sql .= "LIMIT $start, $rows_per_page";
$result = mysql_query($sql, $db);
$rows = mysql_num_rows($result);
for ($i = 0; $i < $rows; $i++) {
$description = mysql_result($result, $i, 0);
echo "$description = $description<br>n";
}
echo "<p><hr></p>n";
// let's create the dynamic links now
if ($screen > 0) {
$url = "example.php?screen=" . $screen - 1;
echo "<a href="$url">Previous</a>n";
}
// page numbering links now
for ($i = 0; $i < $pages; $i++) {
$url = "example.php?screen=" . $i;
echo " | <a href="$url">$i</a> | ";
}
if ($screen < $pages) {
$url = "example.php?screen=" . $screen + 1;
echo "<a href="$url">Next</a>n";
}
?>

export default (filesMap) => {
return new Promise((resolve, reject) => {
let filePromises = [];
for (let name of Object.keys(filesMap)) {
filePromises.push(readFile(filesMap[name]));
}
Promise
.all(filePromises)
.then((filesData) => {
resolve(filesData.reduce((prev, curr) => prev += curr));
}, reject);
});
};

Elegant coding implementations

<?php
namespace AppHttpControllers;
use AppRepositoriesUserRepository;
class UserController extends Controller
{
/**
* The user repository instance.
*/
protected $users;
/**
* Create a new controller instance.
*
* @param UserRepository $users
* @return void
*/
public function __construct(UserRepository $users)
{
$this->users = $users;
}
}

Throwaway request response lifecycle

Uniform Variable Syntax
($object->closureProperty)();

Uniform Variable Syntax
class foo { static $bar = 'baz'; }
class baz { static $bat = 'Hello World'; }
baz::$bat = function () { echo "Hello World"; };
$foo = 'foo';
($foo::$bar::$bat)();

Return Types
function isValidStatusCode(int $statusCode): bool {
return isset($this->statuses[$statusCode]);
}

So....
Should I use? PHP or JS?
