在这个简单的类中，我想要例如 var_dump 规则。但这不起作用。有人有想法吗？

好的，我做了一些改变。它在帖子真假后回馈。有用。这段代码是 OOP 的好方法吗？

class Forms_FormsValidation {

private $_required;
private $_minLength;
private $_maxLength;
private $_alphaNumeric;
private $_errors;

public function __construct($validate, $posts) {
    array_pop($posts);
    foreach ($validate as $arraykey => $value) {            
        foreach ($value as $key => $values) {
            if (method_exists($this, "set$key")) {                    
                $set = 'set'.ucfirst($key);
                $get = 'get'.ucfirst($key);
                $this->$set($posts["$arraykey"], $values);
                if( $this->$get() != '') {
                    $this->_errors[$arraykey] .= $this->$get();
                }                    
            }
        }
    }          
}

public function setValidation(){
    if ( empty($this->_errors) ){return TRUE;}return FALSE;
}
public function getRequired() {
    return $this->_required;
}

public function setRequired($value, $ruleValue) {
    if (empty($value) && $ruleValue == TRUE) {
        $this->_required = 'newwwwwwwwww this field is required';
    }
}

public function getMinLength() {
    return $this->_minLength;
}

public function setMinLength($value, $ruleValue) {
    if (strlen($value) < $ruleValue) {
        $this->_minLength = 'must be longer than' . $ruleValue . '';
    }
}

public function getMaxLength() {
    return $this->_maxLength;
}

public function setMaxLength($value, $ruleValue) {
    if (strlen($value) > $ruleValue) {
        $this->_maxLength = 'must be shorter than' . $ruleValue . '';
    }
}

public function getAlphaNumeric() {
    return $this->_alphaNumeric;
}

public function setAlphaNumeric($value, $ruleValue) {
    if (!preg_match('/^([a-z0-9])+$/i', $value)) {
        $this->_alphaNumeric = 'can only contain letters and numbers';
    }
}

}

$validateUser       = array( 'user' => array ( 'required' => TRUE, 'minLength' => 2,'maxLength' => 15, 'alphaNumeric' => TRUE ));
$validatePassword   = array( 'password' => array ( 'required' => TRUE, 'minLength' => 2,'maxLength' => 15, 'alphaNumeric' => TRUE ));
$_POST = array_map('strip_tags', $_POST);
$formsValidation = new Forms_FormsValidation($validateUser, $_POST); 
$formsValidation = new Forms_FormsValidation($validatePassword, $_POST); 
if ( $formsValidation->setValidation() === TRUE ) {echo 'TRUE';}

var_dump在这个函数中使用

public function getValidationRules()
{
    var_dump($this->_validationRules);
}

var_dump($this->_validationRules);不起作用，因为您试图在类的构造中调用它。只有在您创建类的实例或对象时才会调用此构造。那个时间$this->_validationRules不包含你需要的任何var_dump价值

setValidationRules()

功能。

这意味着当你这样做时

$formsValidation = new Forms_FormsValidation();

构造函数被调用，那时它没有任何价值。

试试这个来获取转储结果：

public function setValidationRules( $validationRules )
{
    $this->_validationRules = $validationRules;
    var_dump($this->_validationRules);
}

调用var_dump($this->_validationRules);内部构造函数时没有显示任何内容，因为$this->_validationRules此时为空。你可以在setValidationRules函数调用之后调用它，它会工作

Var_dump() 在构造函数中工作正常，问题是你需要在创建对象之前初始化成员。

例子：

在构造函数中：

public function __construct() {
     $this->_validationRules = array( 'required' => TRUE, 'minLength' => 2,'maxLength' => 15, 'alphaNumeric' => TRUE );
     var_dump($this->_validationRules);
}

或者您仍然可以在类成员定义中定义变量，如下所示

class Forms_FormsValidation {        
    private $_validationRules = array( 'required' => TRUE, 'minLength' => 2,'maxLength' => 15, 'alphaNumeric' => TRUE );
