使用PSPad开发PHP之收藏Snippet(之一)

上一篇 / 下一篇 2007-11-14 22:57:12

VS和ZEND有的功能PSPad也有,速度要比前者快的多,而且你也可以修改添加插件,使用vbscipt/js,而且它是免费的
这一点是UltraEdit/EditPlus永远也赶不上的地方
今天要介绍的是一个Snippets插件,安装之后,你可以将选中的代码保存起来,下次再用时,只需要按下快捷键即可插入

以下是我今天收集的代码段,看后要顶,请补充,共享...
function dhtmlspecialchars($string) {
   if(is_array($string)) {
       foreach($string as $key => $val) {
           $string[$key] = dhtmlspecialchars($val);
       }
   } else {
       $string = preg_replace('/&((#(\d{3,5}|x[a-fA-F0-9]{4})|[a-zA-Z][a-z0-9]{2,5});)/', '&\\1',
       str_replace(array('&', '"', '<', '>'), array('&', '"', '<', '>'), $string));
   }
   return $string;

    function getClientIP()
{
    $onlineip = '';
    if(getenv('HTTP_CLIENT_IP')) {
        $onlineip = getenv('HTTP_CLIENT_IP');
    } elseif(getenv('HTTP_X_FORWARDED_FOR')) {
        list($onlineip) = explode(',', getenv('HTTP_X_FORWARDED_FOR'));
    } elseif(getenv('REMOTE_ADDR')) {
        $onlineip = getenv('REMOTE_ADDR');
    } else {
        $onlineip = $_SERVER['REMOTE_ADDR'];
    }
    return $onlineip;
}

Gif验证码

<?php
    ob_start();
    session_start();
    $rands = rand(1000,9999);
    header("Content-type: image/gif");
    $_SESSION['reg_num_check'] = $rands;
    $im = @imagecreate(40, 15);
    imagecolorallocate($im, 240, 240, 240);
    $loc = 2;
    $color1=imagecolorallocate($im, 0, 0, 0);
    for($i=0;$i<4;$i++){
        $color=imagecolorallocate($im, rand(0,255), rand(0,255), rand(0,255));
        imagestring($im, 4, ($loc+1), 1, substr($rands,$i,1), $color1);
        imagestring($im, 4, $loc, 0, substr($rands,$i,1), $color);
        $loc += 9;
    }
    Imagegif($im);
    imagedestroy($im);
    ob_end_flush();
?>

    insert语句构造

        function insert( $p_table, $p_values )
    {
        foreach( $p_values as $key => $var )
        {
            $sql_add_sub_name.= " `".$key."` ,";
            $sql_add_var_name.= " '".str_replace("'","\'",$var)."' ,";
        }
        $sql_add_sub_name = substr( $sql_add_sub_name, 0, -1 );
        $sql_add_var_name = substr( $sql_add_var_name, 0, -1 );

        $real_sql = "INSERT INTO ".$p_table." (".$sql_add_sub_name.") VALUES (".$sql_add_var_name.")";
        return $this->query( $real_sql );
    }




    //循环创建路径

    public static function mDir($dir)
    {
        $isc=true;
        if(!is_dir($dir)){
            PubFunction::mDir(dirname($dir));
            if(!mkdir($dir))$isc=false;
        }return $isc;
    }



    php实现多态
    <?php
class Board
{
    function niceDrawing($x)
    {
    //假设这是Board类的一个方法
        $x->draw();
    }
}
abstract class Shape
{
   abstract function draw();
}

class Circle extends Shape
{
    function draw()
    {
        echo "Cricle drawing";
    }
}

class Rectangle extends Shape
{
    function draw()
    {
        echo "Rectangle drawing";
    }
}

$board = new Board();
$obj = new Circle(3,187);
$obj2 = new Rectangle(4,5);
$board->niceDrawing($obj);
//将调用Circle的draw方法
$board->niceDrawing($obj2);
?>

//PHP实现覆盖
class MyClass
{
   function showConstant() {
        echo "a";
    }
}

class MyClassExt extends MyClass
{
    function showConstant()
    {
        parent::showConstant();
        echo "2";
    }
}
$testclass = new MyClassExt();
$testclass->showConstant();

PHP实现重载
<?php
class Myclass {
function Myclass() {
    $name="Myclass".func_num_args();
    @$this->$name();
//注意$this->name()一般是错误的，但是在这里$name是一个将被调用方法的名字
}
function Myclass1($x)
{
    echo "class1";
}
function Myclass2($x,$y)
{
    echo "class2";
}

}
//通过在类中的额外的处理，使用这个类对用户是透明的：
$obj1=new Myclass('1'); //将调用Myclass1
$obj2=new Myclass('1','2'); //将调用Myclass2
?>

将数组序列化成对象保存入cookie
$user_array = array(
     'name' => '张三',
     'age' => '55',
     'sex' => '男'
     );
setcookie('userinfo', base64_encode(serialize($user_array)));

$user_array = unserialize(base64_decode ($_COOKIE['userinfo']));
var_dump($user_array);

//代理类实现

class Proxy
{
private $object;
function __call($name, $params) {
    if ( isset($this->object) )
    {
        if ( method_exists($this->object, $name) )
        {
            return call_user_func_array(array($this->object, $name), $params);
        } else {
            return "method not exists.";
        }
    }
}
function __construct($object)
{
$this->object = $object;
}
}

class Hoge
{
function add($var1, $var2)
{
    return $var1 + $var2;
}
}

$p = new Proxy(new Hoge);

$result = $p->add(1, 2);
echo "result: $result".'<br>';;

$result = $p->sub(5, 3);
echo "result: $result".'<br>';
