php参考手册Filesystem函数(完结了)

 echo fgets($file). "
"; } fclose($file); ?> 

 fwrite($file,"cyg");//把cyg写入demo.php文件中 flock($file,LOCK_UN);//（无论共享或独占） } else { echo "Error locking file!"; }fclose($file);//关闭文件 

 echo "这是一个目录"; } else{ echo "这不是一个目录"; } ?> 

 echo "1"; } else{ echo "0"; } ?> 

 echo "1"; } else{ echo 0; } ?> 

 echo "可读"; } 

 echo ("$file is uploaded via HTTP POST"); } else { echo ("$file is not uploaded via HTTP POST"); } 

 echo ("$file is uploaded via HTTP POST"); } else { echo ("$file is not uploaded via HTTP POST"); } 

 echo ("$file is uploaded via HTTP POST"); } else { echo ("$file is not uploaded via HTTP POST"); } 

 echo 111; } 

原来的： 现在的：

 set_file_buffer($file,0);//设置打开文件的缓冲（内存）大小。 fwrite($file,"Hello World. Testing!666"); fclose($file); }
