The following is the html code.

      Mobile phone number:        *  

This section of code is incomplete. the code for getting and converting should be included in the previous section.

If ajax is used, it is the return value of the request interface.

This may be the convention of the return values of the program specification, so we need to look up how this $ ucresult is assigned a value.

function uc_user_checkemail($email) {return call_user_func(UC_API_FUNC, 'user', 'check_email', array('email'=>$email));}

define('UC_API_FUNC', UC_CONNECT == 'mysql' ? 'uc_api_mysql' : 'uc_api_post');

function uc_api_mysql($model, $action, $args=array()) {global $uc_controls;if(empty($uc_controls[$model])) {include_once UC_ROOT.'./lib/db.class.php';include_once UC_ROOT.'./model/base.php';include_once UC_ROOT."./control/$model.php";eval("\$uc_controls['$model'] = new {$model}control();");}if($action{0} != '_') {$args = uc_addslashes($args, 1, TRUE);$action = 'on'.$action;$uc_controls[$model]->input = $args;return $uc_controls[$model]->$action($args);} else {return '';}}

 $ucresult = uc_user_checkemail($email);

This may be because the return value of the program specification is customary, so we need to look up how this $ ucresult is assigned a value. you said that I don't understand these classes or anything. Is it true that I am a parallel programmer? Understand, but not write
