Compression Streams
Now PHP supports data: protocol w/out "//" like data:text/plain, not data://text/plain,
I tried it.
The data: (» RFC 2397) stream wrapper is available since PHP 5.2.0.
Příklad N.4. Print data:// contents
<?php
// prints "I love PHP"
echo file_get_contents('data://text/plain;base64,SSBsb3ZlIFBIUAo=');
?>
Příklad N.5. Fetch the media type
<?php
$fp = fopen('data://text/plain;base64,', 'r');
$meta = stream_get_meta_data($fp);
// prints "text/plain"
echo $meta['mediatype'];
?>
Tabulka N.8. Wrapper Summary

Note that the official data URI scheme does not include a double slash after the colon - that you must include it when making calls to PHP is an artifact of the designers' misunderstanding of URL syntax.
To automatically convert proper data URIs to ones understood by PHP, you can use code such as the following:
function convertUriForPhp( $uri ) {
if( preg_match('/^data:(?!\\/\\/)(.*)$/',$uri,$bif) ) {
return 'data://' . $bif[1];
} else {
return $uri;
}
}
