php的rename函数用不了
//保存为UseFile5_for_rename.php

  $filepath="C:/Users/Administrator/Desktop/新建文件夹/";
  $readarray=file($filepath."分集梗概.txt");
  $sign1="第";
  $sign2="集"; 
  $nameArray=array();
  if(!$readarray){
  echo "用file函数读取文件失败
";
  }  
  else 
  foreach($readarray as $value){
  if(strstr($value,$sign1)&&strstr($value,$sign2))  
  //使用strpos要注意汉字的字节位
  array_push($nameArray,$value);
  //else echo "找不到"; 
  }
  echo sizeof($nameArray)."
";
   
  //按序重命名文件
   
  $i=1;
   
  foreach($nameArray as $value){
  $value=trim($value); //有必要
  echo $value."
";
  $filename=$filepath."(".$i.")".".txt";
  $value=$filepath.$value.".txt";
  rename($filename,$value);
  $i++;
  if($i>10)break; //文件夹内文件的总数
  }
   
  //映射法重命名文件
   
  echo "


";
?>

/*
  因为当前路径为UseFile5_for_rename.php文件路径,而我想修改$filepath目录下的10个文件:

  原名为(i).txt (i=1,2,3...,10);

  如果把文件剪切在当前路径下用:

  $filename="(".$i.")".".txt";
  $value=$value.".txt";
  rename($filename,$value);
  可以实现

  那为什么在绝对路径下不可以呢?

------解决方案--------------------
这好像是 php5.3的一个bug,到现在还没更正吗?
------解决方案--------------------
是不是需要权限,没有设置对。不是很清楚,难道是楼上说的?

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP Performance: Identifying and Fixing BottlenecksPHP Performance: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AM

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
