在通过DomDocument（PHP）加载格式不正确的HTML时禁用警告

您可以使用安装临时错误处理程序

set_error_handler

class ErrorTrap {  protected $callback;  protected $errors = array();  function __construct($callback) {    $this->callback = $callback;  }  function call() {    $result = null;    set_error_handler(array($this, 'onError'));    try {      $result = call_user_func_array($this->callback, func_get_args());    } catch (Exception $ex) {      restore_error_handler();   throw $ex;    }    restore_error_handler();    return $result;  }  function onError($errno, $errstr, $errfile, $errline) {    $this->errors[] = array($errno, $errstr, $errfile, $errline);  }  function ok() {    return count($this->errors) === 0;  }  function errors() {    return $this->errors;  }}

用法：

// create a DOM document and load the HTML data$xmlDoc = new Domdocument();$caller = new ErrorTrap(array($xmlDoc, 'loadHTML'));// this doesn't dump out any warnings$caller->call($fetchResult);if (!$caller->ok()) {  var_dump($caller->errors());}
