  23 => "http://www.google.com/page5-35.html"
  24 => "http://www.google.com/page5-40.html"
]

Formatting

You can also add a sprintf compatible pattern to format the output.

$str = "http://www.google.com/page[:1:1:5:%02d:].html";
$result = StringSequencer::from($str);

Will return

array:5 [
  0 => "http://www.google.com/page01.html"
  1 => "http://www.google.com/page02.html"
  2 => "http://www.google.com/page03.html"
  3 => "http://www.google.com/page04.html"
  4 => "http://www.google.com/page05.html"
]

Back Reference

If you need to have the same iteration done multiple times in a string (versus having different iterations performed on a string), you can use back references. Keep in mind that while the syntax kinda looks like regular expression back references, it is not.

$str = "http://www.google.com/page[:1:1:5:%02d:]/[\\1].html";
$result = StringSequencer::from($str);

Will return.

array:5 [
  0 => "http://www.google.com/page1/1.html"
  1 => "http://www.google.com/page2/2.html"
  2 => "http://www.google.com/page3/3.html"
  3 => "http://www.google.com/page4/4.html"
  4 => "http://www.google.com/page5/5.html"
