Trouble with PHP build on travis

[Thiruvalluvan MG]

Hi,
The builds on Travis CI have been failing for the past couple of days. The 
error is "The command "php composer-setup.php --version=2.2.5" failed and 
exited with 1 during ." The basic error is: "Could not open input file: 
composer-setup.php". Can someone familiar with the issue resolve this?
Thanks a ton.
