使用PHP读取文件

PHP的IO操作比起java来说简单的不是一点点，同样的读取文件java的处理比较繁琐，php基本上就是几句代码就出来了。从这些地方来说php真的是比较方便，这次分享的是php文件操作的读取几种文件的方法

1.读取普通文件主要就是文本文件的读取方法

读取txt文本文件php给我们提供了比较常用的两种方法，还是先从简单的说起代码如下

Copy after login

这种方法用于读取比较小的文件效果最好，如果读取大文件可能对apache造成很大的冲击，因为文件是一整个直接被读取出来。所以使用下面这种可能比较好 

0){
   	  	$str.=fread($fp,$buf);
   	  	$tem+=$buf;
   	  }
   	  echo $str;
   	 
   }else{
   	 die("文件不存在");
   }
   fclose($fp);
   
?>
Copy after login

2.读取资源文件或者配置文件

对于资源文件或者配置文件，php也为我们提供了对于的方法，个人觉得php读这种文件的方法很好使，来简单看下我的资源文件

下面把读取资源文件的代码贴出来

 $value ) {
        echo "$key : $value"."";
      }
   }else{
   	 die("文件不存在");
   }
  
   
?>
Copy after login

下面是程序运行效果图

是不是比java操作文件要简单呢？得意
