PHP: Calling a parent constructor?

I am having a difficult time understanding the purpose for the construct. In the code challenge, i am asked to "Create a constructor for the Trout class with three parameters in order: $name, $flavor, and $record. Call the parent constructor inside the new constructor."

HERE IS MY CODE: Can anyone guide me in the right direction to comprehend this concept?

<?php class Fish { public $common_name; public $flavor; public $record_weight;

function __construct($name, $flavor, $record){
    $this->common_name = $name;
    $this->flavor = $flavor;
    $this->record_weight = $record;
}

public function getInfo() {
    $output  = "The {$this->common_name} is an awesome fish. ";
    $output .= "It is very {$this->flavor} when eaten. ";
    $output .= "Currently the world record {$this->common_name} weighed {$this->record_weight}.";
    return $output;
}

}

class Trout extends Fish { function construct($name, $flavor, $record){ parent::construct(); $this->common_name = $name; $this->flavor = $flavor; $this->record_weight = $record; } } ?>

<?php

class Trout {


function __construct($name, $flavor, $record){
    $this->common_name = $name;
    $this->flavor = $flavor;
    $this->record_weight = $record;
}

}
?>


class TroutExtra extends Trout {

  function __construct(){
     parent::__construct("name","flavour","record");
  }

}

This might help

<?php
class Trout extends Fish {
  function __construct($name, $flavor, $record) {
  parent::__construct($name, $flavor, $record);
  }
?>

this works for step 2:

class Trout extends Fish { function __construct($name, $flavor, $record) { parent::__construct($name, $flavor, $record); }

I too am stuck on this, I tried both of the above and they didn't seem to help. Constructors seem to be a bit confusing for me. I've completed step 1 of this challenge without issues, but I am stuck on step 2.

I am stuck at this part also. Here is my code.

class Trout extends Fish { function_construct($name, $flavor, $record){ parent::_construct($name, $flavor, $record); } }

It looks like this has worked for other people but it is not working for me. What am I doing wrong?

For me, there was a missing curly brace:

class Trout extends Fish { function __construct($name, $flavor, $record){ parent:: __construct($name, $flavor, $record); } }
