php - How do I prepend file to beginning?

Question

In PHP if you write to a file it will write end of that existing file.

How do we prepend a file to write in the beginning of that file?

I have tried rewind($handle) function but seems overwriting if current content is larger than existing.

Any Ideas?

$prepend = 'prepend me please';

$file = '/path/to/file';

$fileContents = file_get_contents($file);

file_put_contents($file, $prepend . $fileContents);
