How to Check if a Variable Contains a URI in PHP 7.4

I use the parse_url function to get the scheme and check whether it is http or https. The final filtered results are as follows, which meet expectations

1. Now I need to extract data in URI format from a one-dimensional array. The printout of the one-dimensional array is shown in Figure 1.

Plaintext

array(134) {
  [14]=>
  bool(false)
  [15]=>
  string(0) ""
  [16]=>
  string(6) "center"
  [17]=>
  string(7) "#ffffff"
  [18]=>
  string(95) "https://xxx.s3.us-east-2.amazonaws.com/image/736589fac73c7dfdbf61efadb49a95fb9af16efb.jpeg"
  [19]=>
  string(30) "Image with text overlay"
  [20]=>
  string(8) "Shop Now"
}

2. The implementation based on filter_var is as follows, and the printout is as follows. It does not meet expectations because it includes: internal://policy_pages/29

PHP

foreach ($images->all() as $image) {
	var_dump($image, filter_var($image, FILTER_VALIDATE_URL));
	echo "\n";
}
Plaintext

string(11) "collections"
bool(false)

bool(false)
bool(false)

string(6) "center"
bool(false)

string(4) "grid"
bool(false)

string(18) "this is collection"
bool(false)

string(19) "main-index-carousel"
bool(false)

string(5) "slide"
bool(false)

string(0) ""

bool(false)
