I’m running WAMP on Windows 7 64 Bits.
The PATH variable is set to c:\wamp\bin\php\php5.3.13\

I’m trying to install Symfony and I do not understand why first line runs and not the second:

This runs successfully:

php c:\wamp\bin\php\php5.3.13\composer.phar update

This line fails:

php composer.phar update

With the error:

“Could not open input file: composer.phar”

What can explain this?

get_include_path returns : `

.;C:\wamp\bin\php\php5.3.13\php\PEAR`.

Does this mean that if composer.phar is not in PEAR directory ‘php composer.phar update’ will not work?

You should try this instead:

composer.phar update

Why would php be aware of your $PATH variable?

Plus, I think $PATH is only used by your shell when dealing with the first word of your command line.
