Deleting files in php is very simple. Just use the unlink function to complete the deletion. If you want to delete all files in a directory, we need to use recursive operation to delete the directory.

Remember the lesson from PHP file creation, we created a file called testFile.txt.

The code is as follows

代码如下

复制代码

$myFile = "testFile.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
fclose($fh);
判断是否删除了.

$myFile = "testFile.txt";
unlink($myFile);

Copy code

代码如下	复制代码
$filename = 'file.txt'; fopen($filename,'a+'); if(!unlink($filename)) { echo "文件{$filename}删除失败"; } else { echo "文件{$filename}删除成功"; } ?>

$myFile = "testFile.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
fclose($fh);
Determine whether it has been deleted.

$myFile = "testFile.txt";
unlink($myFile);

代码如下

复制代码

$filename = 'file.txt';
