PHP function to check file existence by path

Last update on December 20 2024 10:27:24 (UTC/GMT +8 hours)

Write a PHP function that takes a file path as input and checks if the file exists.

Sample Solution:

PHP Code :

<?php
function checkFileExists($filePath) {
    if (file_exists($filePath)) {
        echo "File exists at path: " . $filePath;
    } else {
        echo "File does not exist at path: " . $filePath;
    }
}  
// Usage:
  $filePath = "test.txt";
//$filePath = "i:/test.txt";
checkFileExists($filePath);
?>

Sample Output:

File does not exist at path: test.txt
File exists at path: i:/test.txt

Explanation:

In the above exercise -

Inside the function, we use the file_exists() function to check if the file exists at the given path. If the file exists, we display a message indicating its existence along with the file path. If the file does not exist, we display a message indicating that the file does not exist along with the file path.
To use this function, you can provide the file path as an argument when calling the checkFileExists() function.
When you run this program, it will output either "File exists at path: <file path>" or "File does not exist at path: <file path>", depending on whether the file exists or not.
