php curl用法

在php教程使用curl时必须先在php.ini中开启extension=php_curl.dll前面的;去了，才行哦，curl是php中一款内置的浏览器，它可以模仿用户浏览信息进行网站浏览，等下面来看一实例。

function postpage($url)
{
$response = "";
$rd=rand(1,4);
$proxy='http://221.214.27.253:808';
if($rd==2) $proxy='http://222.77.14.56:8088';
if($rd==3) $proxy='http://202.98.123.126:8080';
if($rd==4) $proxy='http://60.14.97.38:8080';
if($url != "") {
$ch = curl_init($url);
curl_setopt($ch, curlopt_header, 0);
curl_setopt($ch, curlopt_returntransfer, true);
curl_setopt($ch, curlopt_proxy, $proxy);
$response = curl_exec($ch);
if(curl_errno($ch)) $response = "";
curl_close($ch);
}
return $response;
}

php教程 效率的字符串处理方法

<?php
$str = array(
"helloworld",
"howareyou",
"cpufrequency",
"windows7ready",
"newedition2",
"downloadurllist",
"heisasuperhero",
);

//你的解决方法

/*
正确添加空格后应为：
"helloworld" = "hello world"
"howareyou" = "how are you"
"cpufrequency" = "cpu frequency"
"windows7ready" = "windows 7 ready"
"newedition2" = "new edition 2"
"downloadurllist" = "download url list"
"heisasuperhero" = "he is a super hero"
*/

?>

程序代码

function transfer($input) {
        $newarray = array();
        foreach($input as $i) {
                $arr = str_split($i);
                $word = '';
                foreach($arr as $a) {
                        $ascii = ord($a);
                        $lastword = substr($word, -1);
                        $ascii_1 = ord($lastword);
                        $lastword_ = substr($word, -2, 1);
                        if($ascii > 64 && $ascii < 91) {
                                if($ascii_1 > 96 && $ascii_1 < 122) {
                                        $word .= ' '.$a;
                                } else {
                                        $word .= $a;
                                }

                                                $word .= $a;
                                        } else {

一、   概述

php教程-excelreader   是一个读取 excel xsl   文件内容的一个 php   类。

它的下载网址：  http://sourceforge.net/projects/phpexcelreader/

本博客下载地址：phpexcelreader.zip

测试用excel文件：测试.xls

文件名： phpexcelreader.zip

包含两个必需文件： oleread.inc   、 reader.php   。其它文件是一个应用例子 ,   自述文件等

二、   文件使用

首先 ,   包含 reader   类文件： require_once " reader.php";

新建一个实例： $xl_reader= new spreadsheet_excel_reader ( );

设定编码信息： $xl_reader ->setoutputencoding('utf-8');//不设定可能会是乱码 要和网页显示编码一致

读取 excel   文件信息： $xl_reader->read("filename.xls");

它将导出 excel   文件中所有可以识别的数据存储在一个对象中。数据存储在 2   个数组中，目前没有提供方法 /   函数访问这些数据 .   可以像下面这样简单的使用数组名。

sheets   数组包含了读取入对象的大量数据。它将导出 excel   文件中所有可以识别的数据存储在一个 2   维数组中 $xl_reader->sheets[x][y]   。 x  为文档中的表序号， y  是以下的某个参数 ：

①        numrows -- int --  表的行数

例如： $rows = $xl_reader->sheets[0]['numrows']

②        numcols -- int --  表的列数

例如： $cols = $xl_reader->sheets[0]['numcols']

③        cells -- array --  表的实际内容。是一个 [row][column]   格式的 2   维数组

    例如： $cell_2_4 = $xl_reader->sheets[0]['cells'][2][4] //   行 2,   列 4   中的数据

④        cellsinfo -- array --  表格中不同数据类型的信息。每个都包含了表格的原始数据和类型。这个数组包含 2   部分： raw --  表格原始数据； type --  数据类型。

注：只显示非文本数据信息。

例如： $cell_info = $xl_reader[0]['cellsinfo'][2][4]

$cell_info['raw'] is the raw data from the cell

$cell_info['type'] is the data type

$xl_reader->sheets

原理是从url中提取关键词。参数说明：url及关键词前的字符，然后进行处理与来源判断是那个搜索引擎，这样保存到数据就就行了。

<?php教程
//

$search_url = isset($_get['url'])?$_get['url']:''; //代表传入的地址
/*$search_url = urldecode($search_url);
print_r($search_url);
*/

$config = array(
    "s1"=>array(
        "domain" => "google.com",
        "kw" => "q",
        "charset" => "utf-8"
    ),
    "s3"=>array(
        "domain" => "google.cn",
        "kw" => "q",
        "charset" => "utf-8"
    ),
    "s4"=>array(
        "domain" => "baidu.com",
        "kw" => "wd",
        "charset" => "gbk"
    ),
    "s5"=>array(
        "domain" => "soso.com",
        "kw" => "q",
        "charset" => "utf-8"
    ),
    "s6"=>array(
        "domain" => "yahoo.com",
        "kw" => "q",
        "charset" => "utf-8"
    ),
    "s7"=>array(
        "domain" => "bing.com",
        "kw" => "q",
        "charset" => "utf-8"
    ),
    "s8"=>array(
        "domain" => "sogou.com",
        "kw" => "query",
        "charset" => "gbk"
    ),
    "s9"=>array(
        "domain" => "youdao.com",
        "kw" => "q",
        "charset" => "utf-8"
    ),
);

//函数作用：从url中提取关键词。参数说明：url及关键词前的字符。
function get_keyword($url,$kw_start)

{
    $start = stripos($url,$kw_start);
    $url = substr($url,$start+strlen($kw_start));
    $start = stripos($url,'&');
    if ($start>0)
    {
        $start=stripos($url,'&');
        $s_s_keyword=substr($url,0,$start);
    }
    else
    {
        $s_s_keyword=substr($url,0);
    }
    return $s_s_keyword;
}

$arr_key = array();
foreach($config as $item){
    $sh = preg_match("/b{$item['domain']}b/",$search_url);
    if($sh){
        $query = $item['kw']."=";

        $s_s_keyword = get_keyword($search_url,$query);
        $f_skey=urldecode($s_s_keyword);
        if($item['charset']=="utf-8"){
            $f_skey=iconv( "utf-8","gb2312//ignore",$f_skey); //最终提取的关键词
        }
        $keys = explode(" ",$f_skey);
        $arr_key[$item['domain']] = $keys;
    }
}
echo "<pre>";
print_r($arr_key);

?>
<form action="index.php" method="get">
    <input name="url" size="80"><button type="submit">go</button>
</form>

迅雷地址正则匹配代码

thunder://[a-za-z0-9]*

perl:
thunder://.+
用preg_replace()函数。

迅雷地址分不分大小写？不分的话用pregi_replace()
