Blob

In git, a blob represents a file content. You can't access the file name directly from the Blob object; the filename information is stored within the tree, not in the blob.

It means that for git, two files with different names but same content will have the same hash.

To access a repository Blob, you need the hash identifier:

$repository = new Gitonomy\Git\Repository('/path/to/repository');
$blob = $repository->getBlob('a7c8d2b4');

Get content

To get content from a Blob object:

echo $blob->getContent();

File informations

To get mimetype of a Blob object using finfo extension:

echo $blob->getMimetype();

You can also test if Blob is a text of a binary file:

if ($blob->isText()) {
    echo $blob->getContent(), PHP_EOL;
} elseif ($blob->isBinary()) {
    echo 'File is binary', PHP_EOL;
}
