Nothing horrible here.
I disagree - this is (or should be) a simple, atomic operation...
yet, you've got a function-call, an intermediary variable, a boolean test,
and an unset statement repeating the name of the array you're deleting from.
This should be a simple statement or function/method-call, and in most
other languages it would be...
Really? I can't think of a single language that has a call to remove an
element by value in a key-value hash. Do you have some examples? What do
you do with duplicates?
Ruby can do (using irb)
ruby-1.9.2-p180 :007 > h = {"apple"=>150, "banana"=>300, "lemon"=>300}
=> {"apple"=>150, "banana"=>300, "lemon"=>300}
ruby-1.9.2-p180 :008 > h.delete_if { |k,v| v==300 }
=> {"apple"=>150}
May be we should have something like
array_delete_if($array, function($v, $k=null) { if ($v == 300) return true; })
So array_filter?
I'll use it or like for deleting, but the point of this thread is
"intuitive function for deleting element(s)"
array_delete($array, $value|callable)
would be nicer for users, perhaps.
A callable? Wouldn't that mean you couldn't delete strings? :(
