php soap扩展开启与__soapCall使用问题

php soap扩展简单对象访问协议是交换数据的一种协议规范，是一种轻量的、简单的、基于XML（标准通用标记语言下的一个子集）的协议，它被设计成在WEB上交换结构化的和固化的信息，下面我们来看看小编整理的php soap扩展开启与__soapCall使用问题

例子

<?php

try {

      $client = new SoapClient("http://localhost:8080/Webtest/NewService?wsdl");

 

//    $result = $client->__soapCall("operation",array(4));//fault

//    $result = $client->__soapCall("operation",array("id"=>4));//fault

//    $result = $client->operation(4);//fault

    $result = $client->operation(array("id"=>4));//OK

 

    $back = json_encode($result);

    echo $back;

} catch (SoapFault $fault){

    echo "Error: ",$fault->faultcode,", string: ",$fault->faultstring;

}
?>
//仅有标记为OK的那行可以成功返回数字4，其它返回的都是数字0（参数应该是没有传过去，服务器端id初始是0）。

//手册里soapcall的例子：

<?php

$client = new SoapClient("some.wsdl");

$client->SomeFunction($a, $b, $c);

 

$client->__soapCall("SomeFunction", array($a, $b, $c));

$client->__soapCall("SomeFunction", array($a, $b, $c), NULL,

new SoapHeader(), $output_headers);

 

 

$client = new SoapClient(null, array('location' => "http://localhost/soap.php",

'uri' => "http://test-uri/"));

$client->SomeFunction($a, $b, $c);

$client->__soapCall("SomeFunction", array($a, $b, $c));

$client->__soapCall("SomeFunction", array($a, $b, $c),

array('soapaction' => 'some_action',

'uri' => 'some_uri'));

?>

GD库是php中一个默认的强大的图片处理库了，我们可以利用它来对图片进行一些操作或生成图片的操作，下面我们来看文字图片水印缩略图在php中的实例。

一：添加文字水印 使用方法

require 'image.class.php'
$src="001.jpg";
$content="hello";
$font_url="my.ttf";
$size=20;
$image=new Image($src);
$color=array(
0=>255,
1=>255,
2=>255,
2=>20
);
$local=array(
'x'=>20,
'y'=>30
);
$angle=10;
$image->fontMark($content,$font_url,$size,$color,$local,$angle);
$image->show();

二：图片缩略图 使用方法：

require 'image.class.php'
$src="001.jpg";
$image=new Image($src);
$image->thumb(300,200);
$image->show();

三：image.class.php

class image{
private $info;
private $image;
public function __contruct($src){
$info= getimagesize($src);
$this->info=array(
'width'=> $info[0],
'height'=>$info[1],
'type'=>image_type_to_extension($info[2],false),
'mime'=>$info['mime'],
 
);
$fun="imagecreatefrom{$this->info['type']}";
 
$this->image= $fun($src);
 
}
 
//缩略图
public function thumd($width,$height){
$image_thumb= imagecreatetruecolor($width,$height);
imagecopyresampled($image_thumb,$this->image,0,0,0,0,$width,$height,$this->info['width'],$this->info['height']);
imagedestroy($this->image);
$this->image=$image_thumb;
 
}
//文字水印
public function fontMark($content,$font_url,$size,$color,$local,$angle){
 
$col=imagecolorallocatealpha($this->image,$color[0],$color[1],$color[2],$color[3]);
$text=imagettftext($this->image,$size,$angle,$local['x'],$local['y'],$col,$font_url,$content);
}
//输出图片
public function show()
{
header("Content-type:",$this->info['mime']);
 
$func="image{$this->info['type']}";
$func($this->image);
 
}
public function save($nwename){
$func="image{$this->info['type']}";
//从内存中取出图片显示
$func($this->image);
//保存图片
$func($this->image,$nwename.$this->info['type']);
 
}
public function _destruct(){
 
imagedestroy($this->image);
}
 
}

本文我们来分享用php如何识别用户是通过 PC、iPad 还是手机，然后我们还可以看看腾讯的通过JS语句判断WEB网站的访问端是电脑还是手机。

先我们来看看一段用php如何识别用户是通过 PC、iPad 还是手机来访问网站？

<?php
$uAgent = $_SERVER['HTTP_USER_AGENT'];
$osPat = "mozilla|m3gate|winwap|openwave|Windows NT|Windows 3.1|95|Blackcomb|98|ME|XWindow|ubuntu|Longhorn|AIX|Linux|AmigaOS|BEOS|HP-UX|OpenBSD|FreeBSD|NetBSD|OS\/2|OSF1|SUN";
if(preg_match("/($osPat)/i", $uAgent ))
{
    echo "来着PC访问";
}
else
{
    echo "其他终端访问";
}
 
?>

如何判断访问网站的机器类型-如何判断ipad

如何判断是否是 iPad 浏览器呢，关键是看它的 User Agent 中是否有 iPad。iPad 使用的是 Safari Mobile 浏览器，他的的 User Agent 是：

Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10

function is_iPad(){        
 [object Object] [object Object] [object Object]var ua = navigator.userAgent.toLowerCase();
 [object Object] [object Object] [object Object]if(ua.match(/iPad/i)=="ipad") {                
 [object Object] [object Object] [object Object] [object Object] [object Object] [object Object]return true;
 [object Object] [object Object] [object Object]} else {
 [object Object] [object Object] [object Object] [object Object] [object Object] [object Object]return false;
 [object Object] [object Object] [object Object]}
}


$is_iPad = (bool) strpos($_SERVER['HTTP_USER_AGENT'],'iPad');

RewriteCond %{HTTP_USER_AGENT} ^.*iPad.*$
RewriteRule ^(.*)$ http://ipad.fairyfish.net [R=301]

JS 判断浏览器客户端类型(ipad,iphone,android)

    <script type="text/javascript">  
       var bForcepc
    = fGetQuery("dv") == "pc";   
       function
    fBrowserRedirect(){   
           var sUserAgent = navigator.userAgent.toLowerCase();  
           var bIsIpad = sUserAgent.match(/ipad/i) ==
    "ipad";    
           var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";  
           var bIsMidp = sUserAgent.match(/midp/i) == "midp";  
           var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";  
           var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";  
           var bIsAndroid = sUserAgent.match(/android/i) == "android";  
           var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";

php本身对于多线程处理是不够理想的，但如果我们使用pthreads性能会有所提高了，下面来看一个PHP多线程pthreads使用例子

<?php
declare(ticks = 1);
$running = 1;
 
//信号处理函数
function sig_handler($signo)
{
  switch ($signo) {
  case SIGINT:
    finish();
    break;
  default:
    break;
  }
}
 
pcntl_signal(SIGINT, "sig_handler");
class test extends \Thread {
  public $url;
  public $result;
 
  public function __construct($url) {
    $this->url = $url;
  }
 
  public function run() {
    if ($this->url) {
      $this->result = model_http_curl_get($this->url);
    }
  }
}
function model_http_curl_get($url) {
  $curl = curl_init(); 
  curl_setopt($curl, CURLOPT_URL, $url); 
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
  curl_setopt($curl, CURLOPT_TIMEOUT, 5); 
  curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2)'); 
  $result = curl_exec($curl); 
  curl_close($curl); 
  return $result; 
}
for ($i = 0; $i < 500; $i++) {
  $urls[] = 'http://www.baidu.com/s?wd='. rand(10000, 20000);
}
 
$pool = array();
for ($i=1;$i<=5;$i++) {
  $key = uniqid();
  $url = array_shift($urls);
  $pool[$key] = new test($url);
  $pool[$key]->start();
  echo "启动线程$key\n";
}
while ($urls && $running) {
  foreach ($pool as $key=>$worker) {
    if(! $worker->isRunning()){
      //unset($pool[$key]);
      echo "线程".$key."已结束\n";
      $url = array_shift($urls);
      $pool[$key] = new test($url);
      $pool[$key]->start();
      echo "启动线程$key\n";
    }
  }
  usleep(1000);
}
 
function finish() {
  global $running;
  global $pool;
  $running = 0;
  echo "接收到信号，等待运行中线程结束\n";
  foreach ($pool as $key=>$worker) {
    if ($pool[$key]->join()) {
      var_dump($pool[$key]->result);
    }
  }
}

在我们使用php实现文件下载时很多时间你会发现下载无法知道要下载文件的大但了，这个是开发者并未使用Accept-Length来获取下载文件大小了，下面我们一起来看看Accept-Length获取下载文件的大小例子
