   Executes the regular expression
   match with multibyte support, and returns <literal>1</literal> if matches are found.
   If the optional <parameter>regs</parameter> parameter was specified, the function
   returns the byte length of matched part, and the <type>array</type>
   <parameter>regs</parameter> will contain the substring of matched
   string. The function returns <literal>1</literal> if it matches with the empty
   string. If no matches are found or an error happens, &false; will be
   returned.
