本文实例讲述了php通过文件流方式复制文件的方法。分享给大家供大家参考。具体分析如下:

php的stream_copy_to_stream()函数可以被用来将一个流中的数据复制到另一个。下面的代码演示了通过流的方式复制文件的代码

<&#63;php 
  function stream_copy($src, $dest) 
  { 
    $fsrc = fopen($src,'r'); 
    $fdest = fopen($dest,'w+'); 
    $len = stream_copy_to_stream($fsrc,$fdest); 
    fclose($fsrc); 
    fclose($fdest); 
    return $len; 
  } 
&#63;>

希望本文所述对大家的php程序设计有所帮助。
