Re: ArrayPath

In every project I have worked on in the last few years, I've implemented this. If I have an array that I can't be sure is well formed and need to get a value at any depth without triggering expensive notices, the recommended way today is to check if each value is set and is an array: http://3v4l.org/23c9i With this functionality, I can simply do: array_get('key1.key2', 'default') On Tue, Oct 7, 2014 at 11:18 AM, Mike Willbanks <pencap@gmail.com> wrote: > On Tue, Oct 7, 2014 at 12:15 PM, Johannes Schlüter <johannes@schlueters.de> > wrote: > >> On Tue, 2014-10-07 at 17:05 +0100, Mathias Grimm wrote: >> > Hi, >> > I would like to suggest something for php like a class I am using >> > >> > https://github.com/mathiasgrimm/arraypath >> > >> > The reason is to access arrays like this: >> > >> > $idx3 = ArrayPath::get('idx1/idx2/idx3', $_POST, >> > 'myDefaultValue'); >> >> what hppens if my array has a / as part of the key?
