Search php binary in user's $PATH is more flexibel

[phaldan]

When I try to run phpca I get the following error:

$ phpca
bash: phpca: /usr/bin/php: bad interpreter: No such file or directory

Not everyone has the php binary in /usr/bin. For example my binary is located in /usr/local/bin. I replaced the interpreter #!/usr/bin/php in phpca with #!/usr/bin/env php to search dynamically for the php binary in user's $PATH.

OK, thanks for addition!
