MaplePHP - DTO

Using a DTO library in PHP provides benefits such as encapsulating data, enforcing immutability, validating data, facilitating data transformation, maintaining API compatibility, reducing coupling, improving code readability, and simplifying testing.

Usage

The easiest way is to always start from the Traverse class and this will give you the most control.

use MaplePHP\DTO\Traverse;

$obj = Traverse::value(["firstname" => "<em>daniel</em>", "lastname" => "doe", "slug" => "Lorem ipsum åäö", "price" => "1999.99", "date" => "2023-08-21 14:35:12", "feed" => [
		"t1" => ["firstname" => "<em>john 1</em>", "lastname" => "doe 1"],
		"t2" => ["firstname" => "<em>jane 2</em>", "lastname" => "doe 2"]
	]
]);

Traversing the data

echo $obj->feed()->t1()->firstname();
// <em>john 1</em>

Traversing the feed

foreach($obj->feed()->fetch()->get() as $row) {
	echo $row->firstname."<br>";
}
// <em>john 1</em>
// <em>jane 2</em>

Handlers

You can access some Handler to make your life easier: Str, Uri, Num, DateTime, Arr, ...see Format dir for more

Traversing and modify string

echo $obj->feed()->t1()->firstname("Str")->stripTags()->ucfirst()
// John 1

foreach($obj->feed()->fetch()->get() as $row) {
	echo $row->firstname("Str")->stripTags()->ucfirst()."<br>";
}
// John 1
// Jane 2

Examples

echo $obj->firstname("Str")->stripTags()->ucfirst()."<br>";
// Daniel

echo $obj->price("Num")->toFilesize()."<br>";
// 1.95 kb

echo $obj->price("Num")->round(2)->currency("SEK", 2)."<br>";
// 1 999,99 kr

echo $obj->date("DateTime")->format("y/m/d, \k\l. H:i")."<br>";
// 23/08/21, kl. 14:35

How it works

Traverse

When you pass array and object data to the Traverse object it will make it possible for you to easily traverse the array/object. you can then use one of the Handlers to modify the data when you have traversed to the right position.

use MaplePHP\DTO\Traverse;
$obj = Traverse::value([MIXED_DATA]);
$obj->arrayKey1()->arrayKey2("HANDLER")->modifyFunction1->modifyFunction2();

Format handlers

You can also just access the handlers directly to modify data quickly.

use MaplePHP\DTO\Format;

Format\Str::value([STRING]);
Format\Num::value([NUMBER]);
Format\Arr::value([ARRAY]);
Format\DateTime::value([STRING]);

Example

echo Format\Str::value("lorem")->ucfirst();
// Lorem
