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 ="
 \ 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 );}
