为什么Laravel集合where（）和whereIn（）在本地和在线环境中的工作方式不同

Question

Thanks, I'd already figure out what happened. Because The version of Laravel is different between local and online. the parameter in Laravel 5.3 and 5.2 collection where() are different.

____ This is what show in tinker on Windows/Mac [ Laravel 5.3 ]___

>>> $a = collect([['a'=>1,'b'=>2],['a'=>'1','b'=>3]])
=> Illuminate\Support\Collection {#852
     all: [
       [
         "a" => 1,
         "b" => 2,
       ],
       [
         "a" => "1",
         "b" => 3,
       ],
     ],
   }

>>> $a->where('a',1)
=> Illuminate\Support\Collection {#877
     all: [
       [
         "a" => 1,
         "b" => 2,
       ],
       [
         "a" => "1",
         "b" => 3,
       ],
     ],
   }

>>> $a->whereIn('a',[1])
=> Illuminate\Support\Collection {#877
     all: [
       [
         "a" => 1,
         "b" => 2,
       ],
       [
         "a" => "1",
         "b" => 3,
       ],
     ],
   }

_ And This is what show on CentOS server[ Laravel 5.2 ]

>>> $a = collect([['a'=>1,'b'=>2],['a'=>'1','b'=>3]])
=> Illuminate\Support\Collection {#1414
     all: [
       [
         "a" => 1,
         "b" => 2,
       ],
       [
         "a" => "1",
         "b" => 3,
       ],
     ],
   }

>>> $a->where('a',1)
=> Illuminate\Support\Collection {#1394
     all: [
       [
         "a" => 1,
         "b" => 2,
       ],
     ],
   }

>>> $a->whereIn('a',[1])
=> Illuminate\Support\Collection {#1388
     all: [
       [
         "a" => 1,
         "b" => 2,
       ],
     ],
   }

I had read Laravel collection doc, and it said, whereIn is same as whereInLoose(however whereInLoose was removed since 5.3), but on my server, whereIn work just like whereInStrict, when I not sure about what a numeric collection value type is, it always find nothing in a collection, then result in a fatal error. Does someone know what and why it happens , Thanks !
