Bug #13439 Updated: unbound .* patterns don't work properly

ID: 13439 Updated by: john@scl.co.uk Reported By: john@scl.co.uk -Status: Bogus +Status: Open Bug Type: Regexps related PHP Version: 4.0.5 New Comment: Derick! This _is_ a bug! I've now upgraded to 4.2.1 and the behaviour remains the same. Consider just these two: ereg_replace('.+','b','aa') -> b ereg_replace('.*','b','aa') -> bb and this from man 7 regex: "An atom followed by `*' matches a sequence of 0 or more matches of the atom. An atom followed by `+' matches a sequence of 1 or more matches of the atom." How can it NOT be a bug?
