PHPLoad is a lightweight PHP file upload class used to easily manage file upload functions. PHPLoad supports file upload, file verification, file type restrictions, file size restrictions and other functions.

In this tutorial, we will introduce how to use PHPLoad.

Installation

You can get the PHPLoad file from GitHub https://github.com/prasathmani/tiny-php-file-upload-class, or install it through Composer.

Using Composer:

composer require prasathmani/phpload

After downloading the file manually, extract the file into your project.

Using

We will write a simple code example to demonstrate how to use PHPLoad.

//Include class library files
require_once "phpload.inc.php";

//Instantiate PHPLoad
$phpload = new PHPLoad();

//Set file type restrictions
$phpload->setAllowedTypes(array("png","jpg","jpeg"));

//Set file size restrictions
$phpload->setMaxFileSize(1000000);

//Verify the file and save it
if($phpload->validateUpload("user_file","uploads/")){

echo "File uploaded successfully!";

}else{

echo "File uploaded failed!";

}

The code above , we first include the phpload.inc.php file and then instantiate the PHPLoad class. We set the file type and file size limits and then call the validateUpload() function to validate the file and save it.

If the uploaded file meets the restriction conditions, this function will return true, otherwise it will return false.

You can also set file type and file size limits in the following ways:

//Set file type limits
$phpload->setAllowedExtensions(array("png", "jpg","jpeg"));

//Set the file size limit
$phpload->setMaxFileSize(1000000);

The above code uses setAllowedExtensions() respectively and setMaxFileSize() function to set file type and file size limits.

You can also use the following function to get information about the uploaded file:

//Get the name of the uploaded file
$phpload->getFileName();

//Get the size of the uploaded file
$phpload->getFileSize();

//Get the type of the uploaded file
$v->getFileType();

//Get the temporary storage path of the uploaded file
$phpload->getTmpPath();
