技术改变生活电影目录核对工具(php)

在这个和谐泛滥的年代,想下载一部电影是如此的不容易,于是我就养成了收藏电影的习惯,2个1T的硬盘收藏了近600部片子,于是很多同事朋友知道后,纷纷向我借硬盘拷电影,于是问题也就来了……

  因为没有硬盘锁,所以我无法控制他们对硬盘是否“动手脚”,比如手误造成的剪切或者误删。虽然我有专门一个记录电影目录的txt文件,如下

  

 

但要一个一个核对过去,不仅浪费时间,而且会造成疲劳导致漏看。既然如此,何不用自己的专业技能来实现我的需求呢,说干就干吧。

 

  首先我要把电影目录从txt文件里读取出来并存为php数组

$fp = fopen('D:\movieList.txt','r');

for($i=0; $i

    $arr[] = trim(substr(fgets($fp),4));

}

fclose($fp);

  其中562是txt文件行数,因为一部电影我就存放一行。因为存放目录里头4个字符是影片清晰度类型,有DVD、BD和MKV三个,所以我用substr(fgets($fp),4)去掉头4个字符,然后用trim去掉首尾的空格,这样最终存放到数组里的片名就不包含任何其他字符了。

  然后要做的就是读取移动硬盘下的电影目录,这里我找的是一段网上读取文件夹下文件名的function

function myreaddir($dir){

    $handle = opendir($dir);

    $i = 0;

    while($file=readdir($handle)){

        if(($file != ". ")&&($file != ".. ")){

            $list[$i] = $file;

            $i = $i+1;

        }

    }

    closedir($handle);

    return $list;

}

$movie = myreaddir("I:\movies");

  这个方法有一个缺陷,就是不能读取子文件下的文件,不过对于我来说已经足够了,大家有兴趣可以在这基础上扩展下去。

  然后就是核对的过程

foreach($arr as $v){

    $f = false;

    foreach($movie as $vv){

        if(strstr($vv,$v)!=""){

            $f = true;

        }

    }

    if(!$f){

        echo $v."
";

    }

}

  核对的核心方法就是判断字符串A里是否包含字符串B,也就是电影文件名里是否包含电影目录里的片名,如果不包含,则输出。

  测试后正确率基本有80%,但有一个bug,比如我的电影目录里有部电影叫“电锯”,但是我文件夹里没有“电锯1024*768.rmvb”,而有部叫“电锯惊魂1024*768.rmvb”的,这样程序是判断通过的。

  唯一的解决办法就是在记录电影目录的时候,就把完整的文件名记录下来,不要只记录“电锯”,而应该记录“电锯1024*768”,或者干脆把文件格式也记录下来,这样在核对的时候,可以直接进行字符串比较。

  如果有更好的解决办法,欢迎告诉我。

How to measure thread performance in C? How to measure thread performance in C? Apr 28, 2025 pm 10:21 PM

Measuring thread performance in C can use the timing tools, performance analysis tools, and custom timers in the standard library. 1. Use the library to measure execution time. 2. Use gprof for performance analysis. The steps include adding the -pg option during compilation, running the program to generate a gmon.out file, and generating a performance report. 3. Use Valgrind's Callgrind module to perform more detailed analysis. The steps include running the program to generate the callgrind.out file and viewing the results using kcachegrind. 4. Custom timers can flexibly measure the execution time of a specific code segment. These methods help to fully understand thread performance and optimize code.

How to use the chrono library in C? How to use the chrono library in C? Apr 28, 2025 pm 10:18 PM

Using the chrono library in C can allow you to control time and time intervals more accurately. Let's explore the charm of this library. C's chrono library is part of the standard library, which provides a modern way to deal with time and time intervals. For programmers who have suffered from time.h and ctime, chrono is undoubtedly a boon. It not only improves the readability and maintainability of the code, but also provides higher accuracy and flexibility. Let's start with the basics. The chrono library mainly includes the following key components: std::chrono::system_clock: represents the system clock, used to obtain the current time. std::chron

How to understand DMA operations in C? How to understand DMA operations in C? Apr 28, 2025 pm 10:09 PM

DMA in C refers to DirectMemoryAccess, a direct memory access technology, allowing hardware devices to directly transmit data to memory without CPU intervention. 1) DMA operation is highly dependent on hardware devices and drivers, and the implementation method varies from system to system. 2) Direct access to memory may bring security risks, and the correctness and security of the code must be ensured. 3) DMA can improve performance, but improper use may lead to degradation of system performance. Through practice and learning, we can master the skills of using DMA and maximize its effectiveness in scenarios such as high-speed data transmission and real-time signal processing.

These methods are implemented through machine learning and natural language processing technologies to help developers improve efficiency and code quality.

How to use string streams in C? How to use string streams in C? Apr 28, 2025 pm 09:12 PM

The main steps and precautions for using string streams in C are as follows: 1. Create an output string stream and convert data, such as converting integers into strings. 2. Apply to serialization of complex data structures, such as converting vector into strings. 3. Pay attention to performance issues and avoid frequent use of string streams when processing large amounts of data. You can consider using the append method of std::string. 4. Pay attention to memory management and avoid frequent creation and destruction of string stream objects. You can reuse or use std::stringstream.

What is real-time operating system programming in C? What is real-time operating system programming in C? Apr 28, 2025 pm 10:15 PM

C performs well in real-time operating system (RTOS) programming, providing efficient execution efficiency and precise time management. 1) C Meet the needs of RTOS through direct operation of hardware resources and efficient memory management. 2) Using object-oriented features, C can design a flexible task scheduling system. 3) C supports efficient interrupt processing, but dynamic memory allocation and exception processing must be avoided to ensure real-time. 4) Template programming and inline functions help in performance optimization. 5) In practical applications, C can be used to implement an efficient logging system.
