FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Informations about the package upload

InitPHP Upload

Validate and store uploaded files on local disk, FTP/FTPS or Amazon S3 through a single, adapter-based API.

Requirements

PHP 8.0 or higher
ext-fileinfo (used to detect the real MIME type of a file)
ext-ftp — only for the FTP adapter
aws/aws-sdk-php — only for the S3 adapter

Installation

For S3 uploads, also install the AWS SDK:

Quick start

File::setPost('photos') reads $_FILES['photos'] and returns a normalized File[], whether the field uploaded one file or many. to() validates the file, stores it, and returns the stored File (with its public URL set) or false if the underlying write failed. Any validation or transfer problem is thrown as an UploadException.

Loading files

Call	Returns	Purpose
`File::setPost(string $key)`	`File[]`	Normalize `$_FILES[$key]` (single or multiple) into `File` objects.
`File::setPath(string $path)`	`File`	Wrap an existing file already on disk.

A file loaded with setPath() is copied to its destination (the source is left in place); a real HTTP upload is moved with move_uploaded_file().

Adapters

All three adapters share the same API — only the credentials differ. The optional second constructor argument is the validation options, identical across adapters.

Adapter	Credentials	Notes
`LocalAdapter`	`dir`, `url`	Creates missing destination directories.
`FTPAdapter`	`host`, `port`, `username`, `password`, `timeout`, `url`, `passive`, `ssl`	Binary mode, passive by default, optional FTPS.
`S3Adapter`	`key`, `secret_key`, `region`, `bucket`, `ACL`, `version`	Requires `aws/aws-sdk-php`.

The `to($target)` argument

$target means the same thing in every adapter: a destination path/key prefix. to('avatars/2026') stores the file under that sub-path:

Local → <dir>/avatars/2026/<name>
FTP → <remote>/avatars/2026/<name> (directories created as needed)
S3 → object key avatars/2026/<name> in the configured bucket

Call to() with no argument to store the file at the destination root.

Validation options

Pass these as the second constructor argument of any adapter (an empty array or 0 means "no restriction"):

Option	Type	Meaning
`allowed_extensions`	`string[]`	Allowed file extensions, matched case-insensitively against the original file name.
`allowed_mime_types`	`string[]`	Allowed MIME types, matched against the real type detected with `finfo` (not the client-supplied one).
`allowed_max_size`	`int`	Maximum size in bytes.

A file that violates any restriction — or whose upload errored — makes to() throw an UploadException.
