Php is dot file

How to read dot files with PHP?

Is there a practice of using dot files to store config info and constants in php? If so, how do I parse them? If not, then what would be a good way to isolate and store sensitive info like db passwords, or other config info?

Yes, there is! Some frameworks like Laravel and Symfony have .env file support out of the box.

In your project, you could use vlucas/phpdotenv, which does exactly what you want and it’s pretty simple to implement, check it out:

1 — Install it using Composer by typing the following command on your terminal:

composer require vlucas/phpdotenv 

2 — Now let’s configure it on your application’s starting point (I’ll assume it is index.php ):

 // index.php include 'vendor/autoload.php'; $dotenv = new Dotenv\Dotenv(__DIR__); $dotenv->load(); // your code goes here. 

3 — Cool, we’re almost there! Now create the .env file at your project’s root directory and populate it with your configs like this:

DB_USER="user" DB_PASSWORD="ultraSecurePassword" DB_NAME="awesome_db" FOO="bar" 

4 — Finally, to retrieve the env values:

 // db.php (naming things is hard) $user = env('DB_USER'); // OR $user = getenv('DB_USER'); // OR $user = $_ENV['DB_USER']; // OR EVEN $user = $_SERVER['DB_USER']; 

Hope it helps! 😉

pathinfo

pathinfo() returns information about path : either an associative array or a string, depending on flags .

Note:

For information on retrieving the current path info, read the section on predefined reserved variables.

Note:

pathinfo() operates naively on the input string, and is not aware of the actual filesystem, or path components such as » .. «.

Note:

On Windows systems only, the \ character will be interpreted as a directory separator. On other systems it will be treated like any other character.

pathinfo() is locale aware, so for it to parse a path containing multibyte characters correctly, the matching locale must be set using the setlocale() function.

Parameters

If present, specifies a specific element to be returned; one of PATHINFO_DIRNAME , PATHINFO_BASENAME , PATHINFO_EXTENSION or PATHINFO_FILENAME .

If flags is not specified, returns all available elements.

Return Values

If the flags parameter is not passed, an associative array containing the following elements is returned: dirname , basename , extension (if any), and filename .

Note:

If the path has more than one extension, PATHINFO_EXTENSION returns only the last one and PATHINFO_FILENAME only strips the last one. (see first example below).

Note:

If the path does not have an extension, no extension element will be returned (see second example below).

Note:

If the basename of the path starts with a dot, the following characters are interpreted as extension , and the filename is empty (see third example below).

If flags is present, returns a string containing the requested element.

Examples

Example #1 pathinfo() Example

$path_parts = pathinfo ( ‘/www/htdocs/inc/lib.inc.php’ );

echo $path_parts [ ‘dirname’ ], «\n» ;
echo $path_parts [ ‘basename’ ], «\n» ;
echo $path_parts [ ‘extension’ ], «\n» ;
echo $path_parts [ ‘filename’ ], «\n» ;
?>

The above example will output:

/www/htdocs/inc lib.inc.php php lib.inc

Example #2 pathinfo() example showing difference between null and no extension

$path_parts = pathinfo ( ‘/path/emptyextension.’ );
var_dump ( $path_parts [ ‘extension’ ]);

$path_parts = pathinfo ( ‘/path/noextension’ );
var_dump ( $path_parts [ ‘extension’ ]);
?>

The above example will output something similar to:

string(0) "" Notice: Undefined index: extension in test.php on line 6 NULL

Example #3 pathinfo() example for a dot-file

The above example will output something similar to:

Array ( [dirname] => /some/path [basename] => .test [extension] => test [filename] => )

Example #4 pathinfo() example with array dereferencing

The flags parameter is not a bitmask. Only a single value may be provided. To select only a limited set of parsed values, use array destructuring like so:

[ ‘basename’ => $basename , ‘dirname’ => $dirname ] = pathinfo ( ‘/www/htdocs/inc/lib.inc.php’ );

var_dump ( $basename , $dirname );
?>

The above example will output something similar to:

string(11) "lib.inc.php" string(15) "/www/htdocs/inc"

• dirname() — Returns a parent directory’s path
• basename() — Returns trailing name component of path
• parse_url() — Parse a URL and return its components
• realpath() — Returns canonicalized absolute pathname

Built-in server assumes path with dot is a file #10578

Built-in server assumes path with dot is a file #10578

Comments

Issue is exactly same as https://bugs.php.net/bug.php?id=74061 and same steps to reproduce.

Description

If the path contains a dot, built-in server assumes it’s a file and tries to serve it. Try the test script with the following URLs. Last one will return 404 response but should route to index.php.

$ curl http://localhost:8000/ $ curl http://localhost:8000/O_o $ curl http://localhost:8000/O.o

php — Download file which name is dot character

I have this script for downloading file:

 if (file_exists($full_path)) < // get mime type $finfo = finfo_open(FILEINFO_MIME_TYPE); $mime = finfo_file($finfo, $full_path); finfo_close($finfo); // get extension $ext = pathinfo( $full_path, PATHINFO_EXTENSION ); $file_name = "here is uploaded file's original name"; header('Content-Description: File Transfer'); header('Content-Type: '.$mime); header('Content-Disposition: attachment; filename="'.$file_name.'.'.$ext.'"'); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate'); header('Pragma: public'); header('Content-Length: ' . filesize($full_path)); readfile($full_path); >Copy code

This works except in case , if file have dot ( . ) as file name.

So, if I have file ..docx , I can upload this on my server, but when I’m trying to download that file with original name, I’m getting file with name docx which type is File and not Microsoft word document .

If try same with regular file names, or some another characters, for example comma, exclamation mark e.t.c, download script works fine and I’m getting real .docx file.
