Question about the course "Extending Object-Oriented PHP"

Just want to ask here for this function what if http:// is https://?

public function setWebsite($value) { $value = trim(filter_var($value, FILTER_SANITIZE_STRING)); if (empty($value)) { $this->website = null; return; } if (substr($value, 0, 4) != 'http') { $value = 'http://' . $value; } $this->website = $value; }

Hi Jonah

The function includes:

if (substr($value, 0, 4) != 'http') { 
  // If the first 4 characters of $value ARE NOT EQUAL TO http then...
}

Let's say the $value is "https://www.teamtreehouse.com"

What the substr() function is looking at is the first 4 characters of $value. Therefore it doesn't matter whether it's http or https - the first 4 characters are "http" in either case.

Hope that helps!

Niki
