arrays - Remove leading zeros Ruby -

-

i want remove leading zeros number.i want use integer(i) instead of i.to_i in order rescue nil.

"011,12,h,013,14".split(",").map{|i| integer rescue nil}

i want get:

[11,12,nil,13,14]

instead this:

[9, 12, nil, 11, 14]

what problem?

from documentation of kernel#integer:

integer(arg, base=0) → integer

[…] if arg string, when base omitted or equals zero, radix indicators (0, 0b, , 0x) honored. […]

you're omitting base leading 0 in strings means base-8 (or octal) used conversion integers. integer literals work same way (011 == 9 yields true). if prefixes/radix indicators shouldn't honored , integers represented strings should treated base-10 (or decimal) one, pass 10 base:

"011,12,h,013,14".split(",").map{|i| integer(i, 10) rescue nil} # => [11, 12, nil, 13, 14]

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
