Php parses XML to get values in tags

/** _ Get_xml: The obtained XML file * @ access public indicates that the function is made public * @ param $ _ xmlfile: xml file * $ _ the data array retrieved from XML by html **/function _ get_xml ($ _ xmlfile) {$ _ html = array (); if (file_exists ($ _ xmlfile) {$ _ xml = file_get_contents ($ _ xmlfile); preg_match_all ('/ (. *) <\/Vip>/', $ _ xml, $ _ dom); foreach ($ _ dom [1] as $ _ value) {preg_match_all ('/ (. *) <\/Id>/', $ _ value, $ _ id); preg_match_all ('/ (. *) <\/Username>/', $ _ value, $ _ username); preg_match_all ('/ (. *) <\/Sex>/', $ _ value, $ _ sex); preg_match_all ('/ (. *) <\/Face>/', $ _ value, $ _ face); preg_match_all ('/ (. *) <\/Email>/', $ _ value, $ _ email); preg_match_all ('/ (. *) <\/Qq>/', $ _ value, $ _ qq); $ _ html ['id'] = $ _ id [1] [0]; $ _ html ['username'] = $ _ username [1] [0]; $ _ html ['sex'] = $ _ sex [1] [0]; $ _ html ['face'] =_ _ face [1] [0]; $ _ html ['email '] =$ _ email [1] [0]; $ _ html ['qq'] =$ _ qq [1] [0] ;}} else {_ alert_back ("file does not exist") ;}return $ _ html ;}

Php writes data to XML files

/** _ Set_xml write information to the XML file * @ access public indicates that the function is made public * @ param $ _ xmlfile xml file * @ param $ _ clean indicates the array of information to be written ** /function _ set_xml ($ _ xmlfile, $ _ clean) {$ _ fp = @ fopen ('newuser. xml', 'w'); if (! $ _ Fp) {exit ('System error, file does not exist! ');} Flock ($ _ fp, LOCK_EX); $ _ string = "<? Xml version = \ "1.0 \" encoding = \ "UTF-8 \"?> \ R \ t "; fwrite ($ _ fp, $ _ string, strlen ($ _ string); $ _ string =" \ R \ t "; fwrite ($ _ fp, $ _ string, strlen ($ _ string); $ _ string =" \ t {$ _ Clean ['id']} \ R \ t "; fwrite ($ _ fp, $ _ string, strlen ($ _ string); $ _ string =" \ t {$ _ Clean ['username']} \ R \ t "; fwrite ($ _ fp, $ _ string, strlen ($ _ string); $ _ string =" \ t {$ _ Clean ['sex']} \ R \ t "; fwrite ($ _ fp, $ _ string, strlen ($ _ string); $ _ string =" \ t {$ _ Clean ['face']} \ R \ t "; fwrite ($ _ fp, $ _ string, strlen ($ _ string); $ _ string =" \ t {$ _ Clean ['email ']} \ R \ t "; fwrite ($ _ fp, $ _ string, strlen ($ _ string); $ _ string =" \ t {$ _ Clean ['url']} \ R \ t "; fwrite ($ _ fp, $ _ string, strlen ($ _ string); $ _ string =" "; Fwrite ($ _ fp, $ _ string, strlen ($ _ string); flock ($ _ fp, LOCK_UN); fclose ($ _ fp );}
