Php set file name

Работа с именами файлов в PHP

Набор PHP функций для работы с путями и именами файлов.

Получить имя файла

echo basename('path/file.png'); // file.png

Имя файла без расширения

$info = pathinfo('path/file.png'); echo $info['filename']; // file /* или */ echo pathinfo('path/donut.png', PATHINFO_FILENAME); // file

Получить расширение файла

echo mb_strtolower(mb_substr(mb_strrchr('path/file.png', '.'), 1)); // png /* или */ echo pathinfo('path/file.png', PATHINFO_EXTENSION); // png

Заменить расширение файла

Заменить расширение .jpeg на .jpg:

$file_name = 'file.jpeg'; $file_new = preg_replace('/\.jpeg$/', '.jpg', $file_name); echo $file_new; // file.jpg

Заменить несколько расширений на одно (.jpg, .jpeg, .png на .webp):

$file_name = 'file.jpeg'; $file_new = preg_replace('/\.(jpg|jpeg|png)$/', '.webp', $file_name); echo $file_new; // file.webp

Дописать текст в конец названия файла

$info = pathinfo('path/file.png'); $name = $info['dirname'] . '/' . $info['filename'] . '-' . time() . '.' . $info['extension']; echo $name; // path/file-1610877618.png

Безопасное сохранение файла

Чтобы не затереть существующий файл на сервере можно применить данную функцию.

В функцию передаётся путь и имя файла, если на сервере уже существует такой файл, функция к концу файла приписывает префикс. Также если директория не существует, пытается её создать.

function safe_file($filename) < $dir = dirname($filename); if (!is_dir($dir)) < mkdir($dir, 0777, true); >$info = pathinfo($filename); $name = $dir . '/' . $info['filename']; $prefix = ''; $ext = (empty($info['extension'])) ? '' : '.' . $info['extension']; if (is_file($name . $ext)) < $i = 1; $prefix = '_' . $i; while (is_file($name . $prefix . $ext)) < $prefix = '_' . ++$i; >> return $name . $prefix . $ext; > // Если в директории есть файл log.txt, файл будет сохранен с названием log_1.txt file_put_contents(safe_file(__DIR__ . '/log.txt'), $text);

Simple Change File Name in PHP

In this tutorial, we will create a Simple Change File Name using PHP. This code will launch a modal to update a filename when the user clicks the update button. The system uses the MySQLi UPDATE query to update the new information in the database base on the given file id and also change the file itself using rename(). This PHP built-in function renames the existing folder in the local file server by providing the old filename and new filename. This a user-friendly program. Feel free to modify and use it for your system.

We will be using PHP as a scripting language that interprets in the webserver such as xamp, wamp, etc. It is widely used by modern website application to handle and protect user confidential information.

Getting Started:

First, you have to download & install XAMPP or any local server that runs PHP scripts. Here’s the link for the XAMPP server https://www.apachefriends.org/index.html .

And this is the link for the jquery that I used in this tutorial https://jquery.com/ .

Lastly, this is the link for the bootstrap that I used for the layout design https://getbootstrap.com/ .

Creating Database

Open your database web server then create a database name in it db_change_file ; after that, click Import, then locate the database file inside the folder of the application then click ok.

Creating the database connection

Open your any kind of text editor(notepad++, etc..). Then just copy/paste the code below then name it conn.php.

alert('Successfully uploaded!')"; echo ""; >else< echo ""; echo ""; > > ?>
