1. 8.0 vendor/masterminds/html5/src/HTML5/Parser/Tokenizer.php \Masterminds\HTML5\Parser\Tokenizer::sequenceMatches()

Check if upcomming chars match the given sequence.

This will read the stream for the $sequence. If it's found, this will return true. If not, return false. Since this unconsumes any chars it reads, the caller will still need to read the next sequence, even if this returns true.

Example: $this->sequenceMatches('</script>') will see if the input stream is at the start of a '</script>' string.
