php读取远程图片到本地

php读取远程图片到本地

$message   //文章内容

    //正则(这个还不是)

    $reg = "/<img[^>]*src="(http://(.+)/(.+).(jpg|gif|bmp|bnp))"/isU";

    //把抠出来的 img 地址存放到 $img_array 变量中

    preg_match_all($reg, $message, $img_array, PREG_PATTERN_ORDER);

    //过滤重复的图片

    $img_array = array_unique($img_array[1]);

复制代码第二步. 把$img_array 数组循环一下. 做图片保存和文章位置替换 foreach ($img_array as $img){

        //判断是否是自己网站上的 图片

        if('xxx.com' != get_domain($img)){// 如果这个图片不是自己服务器上的

            //读取图片文件

            $Gimg = new GetImage();

            $Gimg->source = $img;

            $Gimg->save_to = './data/temp/';

            $FILE =  $Gimg->download(); //图片移动到本地

            //保存到相册 得到图片保存的位置

            $img_path = pic_save($FILE,0,'');

            //文本路径替换

            $message = str_replace($img, $img_path, $message);

           

        }

    }

 

    ....这时候 $message 里面已经图片已经替换为自己服务器本地的地址,并且图片也保存到自己的服务器上.

php 经典的分页函数

function multi($total, $perPage, $curPage, $pageUrl, $maxPages = 0, $page = 10, $autoGoTo = TRUE, $simple = FALSE) {
 $multiPage = '';
 $pageUrl .= strpos($pageUrl, '?') ? '&amp;' : '?';
 $realPages = 1;
 if($total > $perPage) {
  $offset = 2;

  $realPages = @ceil($total / $perPage);
  $pages = $maxPages && $maxPages < $realPages ? $maxPages : $realPages;

  if($page > $pages) {
   $from = 1;
   $to = $pages;
  } else {
   $from = $curPage - $offset;
   $to = $from + $page - 1;
   if($from < 1) {
    $to = $curPage + 1 - $from;
    $from = 1;
    if($to - $from < $page) {
     $to = $page;
    }
   } elseif ($to > $pages) {
    $from = $pages - $page + 1;
    $to = $pages;
   }
  }

  $multiPage = ($curPage - $offset > 1 && $pages > $page ? '<a href="'.$pageUrl.'page=1" class="first"'.$ajaxtarget.'>1 ...</a>' : '').
   ($curPage > 1 && !$simple ? '<a href="'.$pageUrl.'page='.($curPage - 1).'" class="prev"'.$ajaxtarget.'>&lsaquo;&lsaquo;</a>' : '');
  for($i = $from; $i <= $to; $i++) {
   $multiPage .= $i == $curPage ? '<strong>'.$i.'</strong>' :
    '<a href="'.$pageUrl.'page='.$i.($ajaxtarget && $i == $pages && $autoGoTo ? '#' : '').'"'.$ajaxtarget.'>'.$i.'</a>';
  }

  $multiPage .= ($curPage < $pages && !$simple ? '<a href="'.$pageUrl.'page='.($curPage + 1).'" class="next"'.$ajaxtarget.'>&rsaquo;&rsaquo;</a>' : '').
   ($to < $pages ? '<a href="'.$pageUrl.'page='.$pages.'" class="last"'.$ajaxtarget.'>... '.$realPages.'</a>' : '').
   (!$simple && $pages > $page && !$ajaxtarget ? '<kbd><input type="text" name="custompage" size="3" onkeydown="if(event.keyCode==13) {window.location=''.$pageUrl.'page='+this.value; return false;}" /></kbd>' : '');

  $multiPage = $multiPage ? '<div class="pages">'.(!$simple ? '<em>&nbsp;'.$total.'&nbsp;</em>' : '').$multiPage.'</div>' : '';
 }
 $maxpage = $realPages;
 return $multiPage;
}

此函数只要传参数就可以有漂亮的分页效果哦，并且支持select下拉设置调转功能
