It s an array  so         won t work  the     means it has to be an empty string     Use count   to identify the array has any elements  count returns a number  1 or greater will evaluate to true  0   false     if  count  status- gt replies   gt  0      your HTML   foreach loop  endif

I think you are trying to check whether the array is empty or not You can do like this      if   result- gt isEmpty             result is not empty  else         result is empty  endif   Reference isEmpty

You should use empty     if   empty  status- gt replies      lt div class  media-body reply-body  gt       foreach   status- gt replies as  reply           lt p gt     reply- gt body    lt  p gt       endforeach  lt  div gt    endif   You can use count  but if the array is larger it takes longer  if you only need to know if its empty  empty is the better one to use

This is my best solution if I understood the question well   Use of  object- gt first   method to run the code inside if statement once  that is when on the first loop  The same concept is true with  object- gt last          if  object- gt first             lt div class  panel user-list  gt             lt table id  myCustomTable  class  table table-hover  gt                 lt thead gt                     lt tr gt                        lt th class  col-email  gt Email lt  th gt                     lt  tr gt                 lt  thead gt                 lt tbody gt       endif       foreach   object as  data           lt tr class  gradeX  gt              lt td class  col-name  gt  lt strong gt     data- gt email    lt  strong gt  lt  td gt           lt  tr gt       endforeach       if  object- gt last                     lt  tbody gt               lt  table gt           lt  div gt       endif

Echoing Data If It Exists      Sometimes you may wish to echo a variable  but you aren t sure if the variable has been set  We can express this in verbose PHP code like so      isset  name     name    Default           However  instead of writing a ternary statement  Blade provides you with the following convenient short-cut       name or  Default           In this example  if the  name variable exists  its value will be displayed  However  if it does not exist  the word Default will be displayed    From https   laravel com docs 5 4 blade displaying-data

Using following code  one can first check variable is set or not using  isset of laravel directive and then check that array is blank or not using  unless of laravel directive   if  isset  names        unless  names          Array has no value      else         Array has value           foreach  names as  name                 name            endforeach       endunless  else     Not defined  endif
