PHP Comments # vs //

Question

Lately I\'ve been using # instead of // for doing single line comments inside my Code. However, I see must of the people prefer //.

Answer 1

For single line comments, there is no significant technical reason for prefering // over the octothorpe (that's what the Zend PHP 5 Certification Study Guide calls #) or vice versa. // seems to the more common choice out there in the wild.
