I have a function to convert the date, but it is returning an error that I could not adjust:

Follow the code below:

<?php

class Prog{

    private $DtBase;

    public function setdata($DtBase){
        $this->data = $DtBase;
    }
    public function getdata(){
        return convertData($this->data);
    }
    public function convertData($data){
        $data = Datetime::createFromFormat('d/m/Y', $data);
    return $data->format('Y-m-d');
    }
}

?>

Error calling function convertData :

Call to undefined function convertData () in Prog.php on line 11

Any tips?

In getData() you need to specify who is the invoker (owner) of this function (method), as in the case of the same object, the $this

Change:

return convertData($this->data);

To:

return $this->convertData($this->data);
