php自动采集内容中带有图片地址的远程图片保存到本地

代码如下

复制代码

function my_file_get_contents($url, $timeout=30) {  if ( function_exists('curl_init') )   {   $ch = curl_init();   curl_setopt ($ch, curlopt_url, $url);   curl_setopt ($ch, curlopt_returntransfer, 1);   curl_setopt ($ch, curlopt_connecttimeout, $timeout);   $file_contents = curl_exec($ch);   curl_close($ch);  }  else if ( ini_get('allow_url_fopen') == 1 || strtolower(ini_get('allow_url_fopen')) == 'on' )     {   $file_contents = @file_get_contents($url);  }  else  {   $file_contents = '';  }  return $file_contents; }

代码如下

复制代码

实现篇
一般情况，用php教程实现上传进度条就下面两种方法：
1.apc扩展（作者是php教程的创始人，5.2后php已经加入apc扩展）
2.pecl扩展模块 uploadprogress
不论是apc还是uploadprogress，都需要编译源码教程，因为原有的php函数根本不可能读取到临时文件夹里的东西。下面来看如何使用以及关键的代码：apc实现方法:
1.安装apc
2.配置php.ini，设置参数 apc.rfc1867=1
3.关键代码：

代码如下	复制代码
if ($_server['request_method'] == ‘post’) {  //上传请求 $status = apc_fetch(’upload_’ . $_post['apc_upload_progress']); $status['done'] = 1; echo json_encode($status);  //输出给用户端页面里的ajax调用，相关文档请自己寻找 exit; } elseif (isset($_get['progress_key'])) {   //读取上传进度 $status = apc_fetch(’upload_’.$_get['progress_key']); echo json_encode($status); exit; }

uploadprogress实现方法：
1.使用pecl 安装uploadprogress
2.php.ini里面设置 uploadprogress.file.filename_template = “/tmp/upd_%s.txt”
3.关键代码：

代码如下	复制代码
if($_server['request_method']==’post’) { if (is_uploaded_file($_files['upfile']['tmp_name'])) { $upload_dir = ‘your_path/’; $ext        = strrchr($_files['video']['name'], ‘.’); $sessid     = $_post['upload_identifier'] ; $tmpfile    = $upload_dir . $sessid; $sessfile   = $upload_dir . $sessid .$ext; if (move_uploaded_file($_files['upfile']['tmp_name'],$tmpfile)) { //上传成功 } }

 

提供一款简单实用的php图片文件上传实例代码

代码如下

复制代码

<html xmlns="http://www.111cn.net/1999/xhtml"> <head> <meta http-equiv="content-type" content="text/html; charset=gb2312" /> <title>php教程图片文件上传实例代码</title> </head> <body> <form action="" method="post" enctype="multipart/form-data" name="form1" id="form1">   <label for="filefield"></label>   <input type="file" name="file" id="filefield" />   <input type="submit" name="button" id="button" value="文件上传" /> </form> </body> </html>

<?

代码如下

复制代码

if( $_post ) {  if( $_files['file'] )  {   $filename = $_files['file']['type'];   $newname ='111cn.net.gif';   if( strtolower( $filename) == 'image/gif' )   {    if( move_uploaded_file($_files['file']['tmp_name'] ,$newname) )    {     //$ext = getimagesize( $newname );     //print_r($ext);     echo '图片上传成功';    }    else    {     die('图片上传失败!');    }   }   else   {    exit('本程序只允许上传gif图片');   }  } }

$_files 说有
$_files[''myfile''][''name'']   客户端文件的原名称。
$_files[''myfile''][''type'']   文件的 mime 类型，需要浏览器提供该信息的支持，例如"image/gif"。
$_files[''myfile''][''size'']   已上传文件的大小，单位为字节。
$_files[''myfile''][''tmp_name'']   文件被上传后在服务端储存的临时文件名，一般是系统默认。可以在php.ini的upload_tmp_dir 指定，但 用 putenv() 函数设置是不起作用的。
$_files[''myfile''][''error'']   和该文件上传相关的错误代码。[''error''] 是在 php 4.2.0 版本中增加的
