The below regex clears the 77 links you provided.^*

(http:\/\/|https:\/\/)?(((www.)?youtu.be\/)|(www.|m.)?youtube.com\/((embed\/|shorts\/)|(\?|(watch\?(dev=inprogress&)?)?)?vi?(\/|=)))(([0-9a-zA-Z_-])+)([$=#&?\/'"\s])(t=([0-9]+(:[0-9](2))*)*)?

It will capture the <video-id> and <start-time>. Start time can be an integer, or an integer followed by a colon followed by a 2-digit-integer followed by colon followed by 2-digit integer..., e.g. t=2055577:33:44:00

In PHP^**, you can id/capture the group pattern, in this case the and patterns, by adding ?<video-id> and ?<start-time> immediately after the opening parenthesis "(" of the capturing parenthesis like this(*): (?<video-id>([0-9a-zA-Z_-])+) and (?<start-time>t=([0-9]+(:[0-9](2))*)*)?

Here is the update regex for PHP with the <video-id> and <start-time> group identifiers:

(http:\/\/|https:\/\/)?(((www.)?youtu.be\/)|(www.|m.)?youtube.com\/((embed\/|shorts\/)|(\?|(watch\?(dev=inprogress&)?)?)?vi?(\/|=)))(?<video-id>([0-9a-zA-Z_-])+)([$=#&?\/'"\s])(?<start-time>t=([0-9]+(:[0-9](2))*)*)?
