As you can see, require takes an object that maps package names (e.g. monolog/monolog) to version constraints (e.g. 1.0.*). Composer uses this information to search for the right set of files in package repositories that you register using the repositories key, or in Packagist, the default package repository.
Lola (song) Lola is a song written by Ray Davies and performed by English rock band the Kinks on their album Lola Versus Powerman and the Moneygoround, Part One. The song details a romantic encounter between a young man and a possible transvestite, whom he meets in a club in Soho, London.
Lola loves dogs. In Miley Get Your Gum she holds a dog named Thor (who is never to be seen again), and in Miley Hurt the Feelings of the Radio Star, Hannah and Lola attend the Animal Rescue Foundation, where Lola gets handed over a dog as soon as she enters the studio, saying: Oh look!
