PHP 类 BaseClass
1.创建一个简单的类
<?php
class Example
{
public $item = 'hello zxl';
public $name;
function Sample()
{
$this->Test();
}
function Test()
{
echo 'ok' . "<br />";
echo $this->item;
$regular = 100;
echo $regular;
}
}
$e = new Example();
$e->Sample();
?>
2.类-类型引用
<?php
//Type Hinting
class Test
{
public function __construct()
{
}
public function Write()
{
echo 'I am writing form test ' . "<br />";
}
}
class Foo
{
public function __construct(Test $a)
{
$this->NewObj = $a;
$this->NewObj->Write();
}
}
new Foo(new Test);
?>
3.类中的各种内置方法
pt1
<?php
//Magic Methods
class Test
{
public $name;
public function Hello()
{
echo 'hello';
}
function __get($param)
{
echo "$param does not exist";
}
function __set($name, $value)
{
echo "you were going to set a property of $name - > $value";
$this->{$name} = $value;
}
function __call($param, $value)
{
echo "you were going to process $param($value)";
print_r($value);
}
}
$test = new Test();
$test->Hello();
$test->nzzzame; //this is not in class goto "__get()"
$test->age=10; //this is not in class goto "__set()"
$test->Something('zzz','xxx','lll'); //this is not in class goto "__call()"
?>
pt2
<?php
//Magic Methods
class Test
{
function __construct()
{
echo 'item created' . "<br />";
}
function __destruct()
{
echo 'item erased' . "<br />";
}
function __toString()
{
return 'this is tostring' . "<br />";
}
function __clone()
{
echo '1' . "<br />";
}
}
$test = new Test();
echo $test;
$test2 = clone $test;
?>
4.简单的文件读写类
Logger.php
<?php
//Logger
require_once('Log.class.php');
$log = new Log();
$log->Write('test.txt' , 'zzzzz');
//echo $log->Read('test.txt');
?>
Log.class.php
<?php
//Logger
class Log
{
private $_FileName;
private $_Data;
/**
*@desc writes to a file
*@param str $strFileName the name of the file
*@param str $strData data to be appended to the file
*/
public function Write($strFileName , $strData)
{
$this->_FileName = $strFileName;
$this->_Data = $strData;
$this->_CheckPermission();
$this->_CheckData();
$handle = fopen($strFileName, 'a+');
fwrite($handle, $strData . "\r\n");
fclose($handle);
}
public function Read($strFileName)
{
$this->_FileName = $strFileName;
$this->_CheckExists();
$handle = fopen($strFileName , 'r');
return file_get_contents($strFileName);
}
private function _CheckExists()
{
if(!file_exists($this->_FileName))
die('the file does not exist ');
}
private function _CheckPermission()
{
//if(!is_writable($this->_FileName))
//die('Change you chmod permissions to ' . $this->_FileName);
}
private function _CheckData()
{
if(strlen($this->_Data) < 1 )
die('null ' . $this->_Data);
}
}
?>
5.数组参数的运算类
<?php
//Decorator Pattern
class Player
{
public $Data = array();
public function __construct(array $info)
{
$this->Data = $info;
}
}
abstract class Player_Decorate
{
abstract public function Add($int);
}
class Player_Str_Decorate extends Player_Decorate
{
public function __construct(Player $p)
{
$this->Player = $p;
//$this->Player->Data['str'] +=5 ;
}
public function Add($int)
{
$this->Player->Data['str'] += $int;
}
}
class Player_Dex_Decorate extends Player_Decorate
{
public function __construct(Player $p)
{
$this->Player = $p;
//$this->Player->Data['dex'] +=5 ;
}
public function Add($int)
{
$this->Player->Data['dex'] += $int;
}
}
$P = new Player(array('str' => 10,'dex' => 15));
echo $P->Data['str'];
echo '<br />';
echo $P->Data['dex'];
echo '<hr />';
$Str = new Player_Str_Decorate($P);
$Str->Add(25);
echo $Str->Player->Data['str'];
echo '<br />';
$Dex = new Player_Dex_Decorate($P);
$Dex->Add(25);
echo $Dex->Player->Data['dex'];
?>
6.算数运算类
<?php
//Scop & Calculator
class Calc
{
public $input;
public $input2;
private $output;
function setInput($int)
{
$this->input = (int) $int;
}
function setInput2($int)
{
$this->input2 = (int) $int;
}
function calculate()
{
$this->output = $this->input * $this->input2;
}
function getResult()
{
return $this->output;
}
}
$e = new Calc();
$e->setInput(5);
$e->setInput2(55);
$e->calculate();
echo $e->getResult();
?>
7.php类中链的方法
chain_Methods.php
<?php
//chain methods
require('cupcake.php');
$cupcake = new Cupcake();
$cupcake->Nuts('10')
->Frosting('chocolate')
->Sprinkles('200');
print_r($cupcake->Cupcake);
?>
cupcake.php
<?php
//chain methods
class Cupcake
{
public $Cupcake = array();
public function Frosting($str)
{
$this->Cupcake['Frosting'] = $str;
return $this;
}
public function Nuts($int)
{
$this->Cupcake['Nuts'] = (int) $int;
return $this;
}
public function Sprinkles($int)
{
$this->Cupcake['Sprinkles'] = (int) $int;
return $this;
}
}
?>
