This package can process uploads and store them with unique names.

It provides a PHP script to process an uploaded file by checking if it has one of the supported file name extensions.

The script also checks if the file has the name of a file that has not yet been uploaded.

If the file passes all the checks, the script moves the file to a separate directory using a hash of the original file name to create a new file named for the stored file.

Recommendations

Recommendation for a PHP class to unique image file uploader
Upload unique image files

Example

<?php
// Define the path to the upload directory
$targetDir = "uploads/";
// Make sure the upload directory exists
if (!file_exists($targetDir)) {
    mkdir($targetDir, 0777, true);
}

if (isset($_FILES["file"])) {
    // Get the file extension
    $fileType = strtolower(pathinfo(basename($_FILES["file"]["name"]), PATHINFO_EXTENSION));
    // Allowed file types
    $allowedTypes = ['jpg', 'png', 'jpeg', 'gif'];

    // Check if the file is an image
    if (in_array($fileType, $allowedTypes)) {
        // Generate a unique name for the file
        $uniqueFileName = md5(time() . rand()) . "." . $fileType;
        $uniqueFilePath = $targetDir . $uniqueFileName;

        // Check if file already exists
        if (!file_exists($uniqueFilePath)) {
            // Try to upload the file
            if (move_uploaded_file($_FILES["file"]["tmp_name"], $uniqueFilePath)) {
                echo "The file " . htmlspecialchars($uniqueFileName) . " has been uploaded.";
            } else {
                echo "Sorry, there was an error uploading your file.";
            }
        } else {
            echo "File already exists. Please try again.";
        }
    } else {
        echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    }
} else {
    echo "No file was uploaded. Please try again.";
}
?>
