如何创建具有权限的文件，然后更改权限

Question

我认为文件所有者存在问题。但我不知道应该如何更改代码。

我的功能：

public static function createFile($fileName, $mode = 0777){ 
     if (! is_string($fileName) || empty($fileName)) { 
      throw new Exception("File name must be a string and can not be empty", 923050); 
     } 

     $touchResult = touch($fileName); 

     if (! $touchResult) { 
      throw new Exception("Error occurs while touch method was executed", 923052); 
     } 

     if (! is_int($mode) || $mode > 511) { 
      throw new Exception('invalid mode value', 923051); 
     } else { 
      $chmodResult = chmod($fileName, $mode); 

      if (! $chmodResult) { 
       throw new Exception("Error occurs while chmod method was executed", 923052); 
      } 
     } 
    } 

测试：

public function testCreateFile(){ 
     $fileToCreate = __DIR__ . "/../../../../../logs/new.txt"; 

     //Delete file if exist 
     if (file_exists($fileToCreate)) { 
      FileHandler::delete($fileToCreate); 
     } 

     //Create file. Default mode 0777 
     FileHandler::createFile($fileToCreate); 
     $this->assertFileExists($fileToCreate); 

     $filePermisson = substr(sprintf('%o', fileperms($fileToCreate)), - 4); 
     $this->assertEquals("0777", $filePermisson); 

     //Change permission of existing file 
     FileHandler::createFile($fileToCreate, 0775); 
     $filePermisson = substr(sprintf('%o', fileperms($fileToCreate)), - 4); 
     $this->assertEquals("0775", $filePermisson); 

    } 

错误：

There was 1 failure:

1) FileHandlerTest::testCreateFile Failed asserting that '0777' matches expected '0775'.

运行clearstatcache();之前的功能fileperms();清除缓存
