Call method once?

PHP
1

Hi guys,

I have a custom made class.
and this class is called repeatedly in the program.
and there is a method which define the array, below is the codes of this method.

public function set_array_container()
    {
        $this->array_container = array('apple', 'orange', 'mango', 'banana', 'guyabano');
        $this->save_array_2_session();
    }

I want this method to be called once while this method
is inside a class that is being called repeatedly.
How do I call this method once?

thanks in advance.

What you want is called a Singleton. I have not touched PHP in many years but there are some great resources on the subject. Here is one I found with a quick Google search.

Simply put, you use a ‘static’ class method as a flag to keep track if the class is currently instantiated.

This is the quick and dirty way.

public function set_array_container()
    {
        static $executed = false;
        if(!$executed) {
          $executed = true;
          $this->array_container = array('apple', 'orange', 'mango', 'banana', 'guyabano');
          $this->ave_array_2_session();
        }
    }

In theory though the callee should be responsible for limiting calls to this method not the method itself.
