//方法一 用while来些fgets一行行读
$file_name="1.txt";

 代码如下 复制代码

$fp=fopen($file_name,'r');

 while(!feof($fp))
 {
  $buffer=fgets($fp,4096);
  echo $buffer."
";
 }
 fclose($fp);


 
// 方法二 用file一次保存到数组再用foreach输出

 代码如下 复制代码
$array = file( $file );
foreach( $array as $v =>$_v )
{
  echo $_v,'
';
}


//方法三用file_get_contents一次读出

 代码如下 复制代码
if( is_file( $file_name ) )
{
 $cn = file_get_contents( $file_name );
 echo $cn;
}
