PHP XML to convert the code to an array

XML-to-array, including the root key, ignoring empty elements and attributes, with significant errors function Xml_to_array ($xml) { $reg = "/< (\\w+) [^>]*?> ([\\x00-\\xff]*?) <\\/\\1>/"; if (Preg_match_all ($reg, $xml, $matches)) { $count = count ($matches [0]); $arr = Array (); for ($i = 0; $i < $count; $i + +) { $key = $matches [1][$i]; $val = Xml_to_array ($matches [2][$i]); Recursive if (Array_key_exists ($key, $arr)) { if (Is_array ($arr [$key])) { if (!array_key_exists (0, $arr [$key])) { $arr [$key] = Array ($arr [$key]); } }else{ $arr [$key] = Array ($arr [$key]); } $arr [$key] = $val; }else{ $arr [$key] = $val; } } return $arr; }else{ return $xml; } } Xml to array, not including root key function Xmltoarray ($xml) { $arr = Xml_to_array ($xml); $key = Array_keys ($arr); return $arr [$key [0]]; } An XPATH-like array selector function Xml_array_select ($arr, $arrpath) { $arrpath = Trim ($arrpath, '/'); if (! $arrpath) return $arr; $self = ' Xml_array_select '; $pos = Strpos ($arrpath, '/'); $pos = $pos? $pos: strlen ($arrpath); $curpath = substr ($arrpath, 0, $pos); $next = substr ($arrpath, $pos); if (Preg_match ("/\\[(\\d+) \\]$/", $curpath, $predicate)) { $curpath = substr ($curpath, 0, Strpos ($curpath, "[{$predicate [1]}]"); $result = $arr [$curpath] [$predicate [1]]; }else $result = $arr [$curpath]; if (Is_array ($arr) &&!array_key_exists ($curpath, $arr)) { Die (' key was not exists: '. $curpath); } Return $self ($result, $next); } If the input array is a full numeric key, the element values are transferred sequentially to the $callback, otherwise they are transferred to $callback function Xml_array_each ($arr, $callback) { if (Func_num_args () <2) die (' Parameters error '); if (!is_array ($arr)) die (' parameter 1 shuld is an array!
