Here is how we can use the StartWith and EndWith rules to validate a string.
Import required classes-
use Webhkp\Pvalidate\Rules\EndWith;
use Webhkp\Pvalidate\Validator;
use Webhkp\Pvalidate\Rules\StartWith;
use Webhkp\Pvalidate\ValidationBuilder;Object Validation
Define a class (MyClass) with properties that require validation:
class MyClass {
public function __construct(
) {
}
#[StartWith('my')]
public string $firstString = 'my first string';
#[StartWith('my')]
public string $secondString = 'My second string';
#[StartWith('MY', true)]
public string $thirdString = 'My third string';
#[EndWith('string')]
public string $fourthString = 'my fourth string';
#[EndWith('STRING')]
public string $fifthString = 'My fifth StrinG';
#[EndWith('string', true)]
public string $sixthString = 'My sixth String';
#[StartWith('MY')]
#[EndWith('string')]
public string $seventhString = 'My seventh String';
#[StartWith('MY', true)]
#[EndWith('STRING', true)]
public string $eighthString = 'My eighth String';
}An instance of MyClass is created, and the Validator::validate method is used to validate the object:
$myObj = new MyClass();
// Validate the object
$validationResponse = Validator::validate($myObj);
var_dump($validationResponse->isValid());
var_dump($validationResponse->getErrors());Direct Usage of Validation Rules
The script demonstrates how to use the StartWith validation rule directly on a string:
$startValidationResponse = (new StartWith("sone"))->safeParse('some string here');
var_dump($startValidationResponse->isValid());
var_dump($startValidationResponse->getErrors());Similarly, it shows how to use the EndWith validation rule:
$rule = new EndWith("test");
$endWithValidation = $rule->safeParse('some string here');
var_dump($endWithValidation->isValid());
var_dump($endWithValidation->getErrors());StartWith and EndWith Rules Builder
The script demonstrates the use of ValidationBuilder to chain multiple validation rules:
$validation = ValidationBuilder::startWith("some")->endWith('string')->safeParse('some sample string');
var_dump($validation->isValid());
var_dump($validation->getErrors());
// var_dump($validation->getMessages());Full Example Code
Here is the full example code-
<?php
require_once "vendor/autoload.php";
use Webhkp\Pvalidate\Rules\EndWith;
use Webhkp\Pvalidate\Validator;
use Webhkp\Pvalidate\Rules\StartWith;
use Webhkp\Pvalidate\ValidationBuilder;
class MyClass {
public function __construct(
) {
}
#[StartWith('my')]
public string $firstString = 'my first string';
#[StartWith('my')]
public string $secondString = 'My second string';
#[StartWith('MY', true)]
public string $thirdString = 'My third string';
#[EndWith('string')]
public string $fourthString = 'my fourth string';
#[EndWith('STRING')]
public string $fifthString = 'My fifth StrinG';
#[EndWith('string', true)]
public string $sixthString = 'My sixth String';
#[StartWith('MY')]
#[EndWith('string')]
public string $seventhString = 'My seventh String';
#[StartWith('MY', true)]
#[EndWith('STRING', true)]
public string $eighthString = 'My eighth String';
}
// Demo
// Create object
$myObj = new MyClass();
// Validate the object
$validationResponse = Validator::validate($myObj);
var_dump($validationResponse->isValid());
var_dump($validationResponse->getErrors());
// Use Start validation rule directly
$startValidationResponse = (new StartWith("sone"))->safeParse('some string here');
var_dump($startValidationResponse->isValid());
var_dump($startValidationResponse->getErrors());
// Check end with as rule
$rule = new EndWith("test");
$endWithValidation = $rule->safeParse('some string here');
var_dump($endWithValidation->isValid());
var_dump($endWithValidation->getErrors());
// Check with validation builder
$validation = ValidationBuilder::startWith("some")->endWith('string')->safeParse('some sample string');
var_dump($validation->isValid());
var_dump($validation->getErrors());
// var_dump($validation->getMessages());Output:
