As th function is not using  this at all  you can add a static keyword just after public and then call  Functions  filter   GET  params       Avoiding the creation of an object just for one method call

To answer your question  the current method would be to create the object then call the method    functions   new Functions     var    functions- gt filter   GET  params       Another way would be to make the method static since the class has no private data to rely on   public static function filter  data     This can then be called like so    var   Functions  filter   GET  params       Lastly  you do not need a class and can just have a file of functions which you include  So you remove the class Functions and the public in the method  This can then be called like you tried    var   filter   GET  params

Within the class you can call function by using      this- gt filter      Outside of the class  you have to create an object of a class   ex   obj   new Functions           obj- gt filter  param         for more about OOPs in php  this example   class test    public function newTest           this- gt bigTest      we don t need to create an object we can call simply using  this        this- gt smallTest         private function bigTest            Big Test Here      private function smallTest            Small Test Here      public function scoreTest            Scoring code here         testObject   new test      testObject- gt newTest      testObject- gt scoreTest      hope it will help

Create object for the class and call  if you want to call it from other pages    obj   new Functions      var    obj- gt filter   GET  params       Or inside the same class instances   methods    try this    var    this- gt filter   GET  params
