Data URI
To ease working with Data URIs, the library comes bundle with a URI specific Data class. This class follows RFC2397
Instantiation
In addition to the defined named constructors, because data URI represents files, you can also instantiate a new data URI object from a file path using the createFromPath named constructor
<?php
use League\Uri\Schemes\Data as DataUri;
$uri = DataUri::createFromPath('path/to/my/png/image.png');
echo $uri; //returns 'data:image/png;charset=binary;base64,...'
//where '...' represent the base64 representation of the file
If the file is not readable or accessible an RuntimeException exception will be thrown. The class uses PHP’s finfo class to detect the required mediatype as defined in RFC2045.
Validation
Even though all URI properties are defined and accessible attempt to set any component other than the path will result in the object throwing a InvalidArgumentException exception. As adding data to theses URI parts will generate an invalid Data URI.
<?php
use League\Uri\Schemes\Data as DataUri;
$uri = DataUri::createFromPath('path/to/my/png/image.png');
$uri->getHost(); //return '' an empty string
$uri->withHost('example.com'); //thrown an InvalidArgumentException
Properties
The data URI class uses the DataPath class to represents its path. using PHP’s magic __get method you can access the object path and get more informations about the underlying file.
<?php
use League\Uri\Schemes\Data as DataUri;
$uriString = 'data:text/plain;charset=us-ascii,Hello%20World%21';
$uri = DataUri::createFromString($uriString);
echo $uri->path->getMediaType(); //display 'text/plain;charset=us-ascii'
echo $uri->path->getMimeType(); //display 'text/plain'
echo $uri->path->getParameters(); //display 'charset=us-ascii'
echo $uri->path->getData(); //display 'Hello%20World%21'
$uri->path->isBinaryData(); //returns false
$fileObject = $uri->path->save('/path/where/to/save/data', 'w');
//$fileObject is a \SplFileObject reference
