PHP Классы - 10

Статические методы и свойства

<?php
	class StaticExample {
		static public $aNum = 0;
		
		static public function sayHello() {
			print "Привет!";
		}
	}
	
	echo StaticExample::$aNum."<br>";
	StaticExample::sayHello();
?>

Для обращения к статическим методам внутри класса используется ключевое слово self

<?php
	class StaticExample {
		static public $aNum = 0;
		
		static public function sayHello() {
			self::$aNum++;
			print "Привет! (" . self::$aNum . ")\n";
		}
	}
	
	echo StaticExample::$aNum."<br>";
	StaticExample::sayHello();
?>

Создадим таблицу в БД

CREATE TABLE products (
	id INTEGER NOT NULL PRIMARY KEY AUTO_INCREMENT,

PHP Классы - 9 Наследование

PHP Классы Наследование

Базовый класс. от которого наследуются два дочерних

<?php
	class ShopProduct {
		public $title;
		public $producerMainName;
		public $producerFirstName;
		public $price;
		public $numPages;
		public $playLength;
		
		function __construct ( $title, $firstName, $mainName, $price, $numPages = 0, $playLength = 0 )
		{
			$this->title = $title;
			$this->producerMainName = $mainName;
			$this->producerFirstName = $firstName;
			$this->price = $price;
			$this->numPages = $numPages;
			$this->playLength = $playLength;
		}
		
		function getProducer() {
			return "{$this->producerFirstName} "."{$this->producerMainName}";
		}
		
		function getSummaryLine() {
			$base = "$this->title ( {$this->producerMainName}, ";
			$base .= "{$this->producerFirstName})";
			return $base;
		}
	}

	class CDProduct extends ShopProduct {
		function getPlayLength() {
			return $this->playLength;
		}
		
		function getSummaryLine() {
			$base = "$this->title ( {$this->producerMainName}, ";
			$base .= "{$this->producerFirstName} )";
			$base .= ": Время звучания - {$this->playLength}";
			return $base;
		}
	}
	
	class BookProduct extends ShopProduct {
		function getNumberOfPages() {
			return $this->numPages;
		}
		
		function getSummaryLine() {
			$base = "$this->title ( {$this->producerMainName}, ";
			$base .= "{$this->producerFirstName} )";
			$base .= ": {$this->numPages} стр.";
			return $base;
		}
	}
?>

Переопределяем конструктор в дочерних классах

<?php
	class ShopProduct {
		public $title;
		public $producerMainName;
		public $producerFirstName;
		public $price;
		
		function __construct ( $title, $firstName, $mainName, $price )
		{
			$this->title = $title;
			$this->producerMainName = $mainName;
			$this->producerFirstName = $firstName;
			$this->price = $price;
		}
		
		function getProducer() {
			return "{$this->producerFirstName} "."{$this->producerMainName}";
		}
		
		function getSummaryLine() {
			$base = "$this->title ( {$this->producerMainName}, ";
			$base .= "{$this->producerFirstName})";
			return $base;
		}
	}

	class CDProduct extends ShopProduct {
		public $playLength;
		
		function __construct ( $title, $firstName, $mainName, $price, $playLength )
		{
			parent::__construct ( $title, $firstName, $mainName, $price );
			$this->playLength = $playLength;
		}
	
		function getPlayLength() {
			return $this->playLength;
		}
		
		function getSummaryLine() {
			$base = "$this->title ( {$this->producerMainName}, ";
			$base .= "{$this->producerFirstName} )";
			$base .= ": Время звучания - {$this->playLength}";
			return $base;
		}
	}
	
	class BookProduct extends ShopProduct {
		public $numPages;
		
		function __construct ( $title, $firstName, $mainName, $price, $numPages )
		{
			parent::__construct ( $title, $firstName, $mainName, $price );
			$this->numPages = $numPages;
		}
	
		function getNumberOfPages() {
			return $this->numPages;
		}
		
		function getSummaryLine() {
			$base = "$this->title ( {$this->producerMainName}, ";
			$base .= "{$this->producerFirstName} )";
			$base .= ": {$this->numPages} стр.";
			return $base;
		}
	}
	
	$product2 = new CDProduct ("Пропавший без вести", "Группа", "ДДТ", 10.99, null, 60.33);
	print "Исполнитель: {$product2->getProducer()}\n";
?>

Переопределим в дочерних классах методы, наследующие от родительского класса

<?php
	class ShopProduct {
		public $title;

			$this->producerFirstName = $firstName;
			$this->price = $price;
		}
		
		function getProducer() {
			return "{$this->producerFirstName} "."{$this->producerMainName}";
		}
		
		function getSummaryLine() {
			$base = "$this->title ( {$this->producerMainName}, ";
			$base .= "{$this->producerFirstName})";
			return $base;
		}
	}

	class CDProduct extends ShopProduct {
		public $playLength;
		
		function __construct ( $title, $firstName, $mainName, $price, $playLength )
		{
			parent::__construct ( $title, $firstName, $mainName, $price );
			$this->playLength = $playLength;
		}
	
		function getPlayLength() {
			return $this->playLength;
		}
		
		function getSummaryLine() {
			$base = parent::getSummaryLine();
			$base .= ": Время звучания - {$this->playLength}";
			return $base;
		}
	}
	
	class BookProduct extends ShopProduct {
		public $numPages;
		
		function __construct ( $title, $firstName, $mainName, $price, $numPages )
		{
			parent::__construct ( $title, $firstName, $mainName, $price );
			$this->numPages = $numPages;
		}
	
		function getNumberOfPages() {
			return $this->numPages;
		}
		
		function getSummaryLine() {
			$base = parent::getSummaryLine();
			$base .= ": {$this->numPages} стр.";
			return $base;
		}
	}
	
	$product2 = new CDProduct ("Пропавший без вести", "Группа", "ДДТ", 10.99, null, 60.33);
	print "Исполнитель: {$product2->getProducer()}\n";
?>

PHP Filter

[Teenie-weenie]

PHP Filter

• filter_var() - Filters a single variable with a specified filter


• filter_var_array() - Filter several variables with the same or different
  filters


• filter_input - Get one input variable and filter it


• filter_input_array - Get several input variables and filter them with
  the same or different filters

<?php
		$int = 123;
		if (!filter_var($int, FILTER_VALIDATE_INT))
		{
			echo ("Integer is not valid");
		}
		else
		{
			echo ("Integer is valid");
		}
	?>

Фильтр с условиями

<?php
		$var = 300;
		$int_options = array(
			"options" => array
			(
				"min_range"=>0,
				"max_range"=>256
			)	
		);
		
		if (!filter_var($int, FILTER_VALIDATE_INT, $int_options))
		{
			echo ("Integer is not valid");
		}
		else
		{
			echo ("Integer is valid");

PHP Exception Handling

[Heidel]

PHP Exception Handling Обработка исключений

<?php
		function checkNum($number)
		{
			if($number>1)
			{
				throw new Exception ("Value must be 1 or below");
			}
			return true;
		}
		
		checkNum(2);
	?>

Try, throw and catch

<?php
		function checkNum($number)
		{
			if($number>1)
			{
				throw new Exception ("Value must be 1 or below");
			}
			return true;
		}
		
		try {
			checkNum(2);
			echo 'If you see this, the number is 1 or below';
			}
			
		catch (Exception $e)
		{
			echo 'Message: ' .$e->getMessage();
		}
	?>

Creating a Custom Exception Class

<?php
		class customException extends Exception 
		{
			public function errorMessage()
			{
				$errorMsg = 'Error on line '.$this->getLine.' in '.$this->getFile()
				.': <b>'.$this->getMessage().'</b> is not a valid E-mail adress';
				return $errorMsg;
			}
		}
		
		$email = "someone@example...com";
		
		try 
		{
			if (filter_var($email, FILTER_VALIDATE_EMAIL) === FALSE)
			{
				throw new customException($email);
			}
		}
		catch (customException $e)
		{
			echo $e->errorMessage();
		}
	?>

Комбинирование кастомных и встроенных исключений (отловится только первое пойманное исключение)

<?php
		class customException extends Exception 
		{
			public function errorMessage()
			{
				$errorMsg = 'Error on line '.$this->getLine.' in '.$this->getFile()
				.': <b>'.$this->getMessage().'</b> is not a valid E-mail adress';
				return $errorMsg;
			}
		}
		
		$email = "someone@example..com";
		
		try 
		{
			if (filter_var($email, FILTER_VALIDATE_EMAIL) === FALSE)
			{
				throw new customException($email);
			}
			
			if (strpos($email, "example") !== FALSE)
			{
				throw new Exception("$email is an example email");
			}
		}
		catch (customException $e)
		{
			echo $e->errorMessage();
		}
		
		catch (Exception $e)
		{
			echo $e->getMessage();
		}
	?>

PHP Error Handling

Проверка существования файла

<?php
			if(!file_exists("welcome.txt"))
			{
				die("File not found");
			}
			else 
			{
				$file = fopen("welcome.txt", "r");
			}			
		?>

Creating a Custom Error Handler

error_function(error_level,error_message,error_file,error_line,error_context)
error_level,error_message - обязательные параметры

Создать функцию обработки ошибок, установить обработчик и создать ошибку (вывод необъявленной переменной)

<?php
		function customError($errno, $errstr)
		{
			echo "<b>Error:</b> [$errno] $errstr<br />";
			echo "Ending sсript";
			die();
		}
		
		set_error_handler("customError");
		
		echo($test);
	?>

<?php
		function customError($errno, $errstr)
		{
			echo "<b>Error:</b> [$errno] $errstr<br />";
			echo "Ending sсript";
			die();
		}
		
		set_error_handler("customError", E_USER_WARNING);
		
		$test = 2;
		if($test > 1)
		{
			trigger_error("value must be 1 or below", E_USER_WARNING);
		}
	?>
