To display the filename under a file in PHP, you can use the basename() function to extract the filename from the file path. Here's an example of how you can achieve this:
1 2 3 4 |
$file = '/path/to/file.txt'; $filename = basename($file); echo "Filename: " . $filename; |
In this example, we define the file path as $file and then use the basename() function to extract the filename from it. The extracted filename is stored in the variable $filename. Finally, we can display the filename using the echo statement by concatenating it with the desired text.

How to display only the filename without the parent folder using PHP?
You can use the basename() function in PHP to display only the filename without the parent folder. The basename() function returns the trailing name component of a path.
Here's an example:
1 2 3 |
$path = '/path/to/parent/folder/filename.txt'; $filename = basename($path); echo $filename; // Output: filename.txt |
In the example above, the basename() function retrieves the filename from the given path and assigns it to the $filename variable. Finally, the filename is echoed to the output.
How to display the filename in uppercase letters using PHP?
To display the filename in uppercase letters using PHP, you can use the strtoupper() function. Here's an example:
1 2 3 4 |
$filename = "example.txt"; $uppercaseFilename = strtoupper($filename); echo "Uppercase Filename: " . $uppercaseFilename; |
Output:
1
|
Uppercase Filename: EXAMPLE.TXT

How can I display the filename using a specific format in PHP?
To display the filename using a specific format in PHP, you can use various string manipulation functions and date functions.
Here is an example that demonstrates displaying the filename with a specific format:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
<?php $filename = "example_file.txt"; // Remove file extension $filename = pathinfo($filename, PATHINFO_FILENAME); // Format the filename $filename = strtoupper($filename); // Convert to uppercase $filename = str_replace("_", "-", $filename); // Replace underscore with dash // Add timestamp $timestamp = date("Ymd_His"); $filename = $timestamp . "_" . $filename; echo $filename; // Output: 20220223_165759_EXAMPLE-FILE ?> |
In this example, the filename is initially set as "example_file.txt". First, we use the pathinfo() function with the PATHINFO_FILENAME flag to remove the file extension, resulting in "example_file". Then, we format the filename by converting it to uppercase using the strtoupper() function and replacing underscores with dashes using the str_replace() function. Finally, we use the date() function to generate a timestamp in the format "Ymd_His" and prepend it to the filename.
The output of this example will be "20220223_165759_EXAMPLE-FILE", assuming the current date and time is February 23, 2022, 16:57:59. You can modify the formatting as per your specific requirements.
How do I display the filename with its modified date using PHP?
To display the filename with its modified date using PHP, you can use the filemtime() function. Here is an example code to achieve this:
1 2 3 4 5 6 7 8 9 10 11 |
<?php $filename = 'example.txt'; if (file_exists($filename)) { $modifiedDate = date("F d Y H:i:s.", filemtime($filename)); echo "Filename: $filename<br>"; echo "Modified Date: $modifiedDate"; } else { echo "File Not Found!"; } ?> |
Replace 'example.txt' with the actual filename you want to display. The filemtime() function retrieves the Unix timestamp of the last modification time of the file, which is then formatted using the date() function to display in a human-readable format.
