Comment(by mailnew2ster):

 Most of them are. empty() is used, for example, to check whether the
 response is empty, which "0" is not, etc.
 As of $length = hexdec( $match[1] );, empty() used there to check for "0",
 but it does not return true for, eg., "00", thus it's better to use hexdec
 first, and then check the integer for 0.
