创建目录

Question

我试图创建一个子目录中的文件文件，但它也没有创造它

$tempFilename = "xml/tempfile.xml"; 
    if(file_exists($tempFilename)) 
      {  
       unlink($tempFilename); 
      } 
     $file = fopen($tempFilename,"w"); 
     $fileTemplate = ($xml); 

Answer 1

使用fwrite：

$tempFilename = "xml/tempfile.xml"; 
// Test if directory exists. 
$dirname = dirname($tempFilename); 
if (!is_dir($dirname)) 
{ 
    mkdir($dirname); 
} 
if(file_exists($tempFilename)){  
    unlink($tempFilename); 
} 
$file = fopen($tempFilename,"w"); 

// Write what you need 
fwrite($file, 'content of my file'); 
fclose($file); 

Answer 2

您可以使用file_put_contents

file_put_contents($tempFilename, '23'); 

Answer 3

试试这个

首先你需要创建目录

$path = '/xml'; 
mkdir($path, 0777, true); 
$tempFilename = "/xml/tempfile.xml"; 
if(file_exists($tempFilename)) 
     {  
      unlink($tempFilename); 
     } 
    $file = fopen($tempFilename,"w"); 
    fwrite($file, '23'); 
fclose($fp);
