我一直在尝试制作一个自定义验证类，但令我困扰的是它只是测试它看到的最后一个元素。我需要它来测试我放入其中的所有内容。

<?php

class Valid {

function validate(array $args){

    $errors = NULL;

    //********************************
    //Find each key validation.
    //********************************
    foreach ($args as $key => $value){


        //*********************************
        //Check for letters only, a-z, A-Z.
        //*********************************
        if ($key == 'letters'){

            $letters = preg_match('/^\pL+$/u', $value) ? TRUE : FALSE;
            $letters_value = $value;
            $letters_array[] = $letters;

        }

        //*********************************
        //Check for numbers only, 0-9.
        //*********************************
        if ($key == 'numbers'){

            $numbers = preg_match('/^[0-9]+$/', $value) ? TRUE : FALSE;
            $numbers_value = $value;
            $numbers_array[] = $numbers;

        }

        //*********************************
        //Check for vaild email address.
        //*********************************
        if ($key == 'email'){

            $email = filter_var($value, FILTER_VALIDATE_EMAIL) ? TRUE : FALSE;
            $email_value = $value;
            $email_array[] = $email;

        }

        //*********************************
        //Check for empty string.
        //*********************************
        if ($key == 'empty'){

            $empty_it = (trim($value) == FALSE) ? TRUE : FALSE;
            $empty_array[] = $empty_it;

        }


    }

    //********************************
    //Check if you failed letters only.
    //********************************
    if ( count($letters_array) != count(array_filter($letters_array)) ) $errors .= 'You can only enter letters a-z or A-Z.<br />';


    //********************************
    //Check if you failed numbers only.
    //********************************
    if ( count($numbers_array) != count(array_filter($numbers_array)) ) $errors .= 'You can only enter numbers 0-9.<br />';


    //*************************************
    //Check if you failed email validation.
    //*************************************
    if ( count($email_array) != count(array_filter($email_array)) ) $errors .= 'You must enter a vaild e-mail address.<br />';


    //*************************************
    //Check if you empty string.
    //*************************************
    if ( count($empty_array) != count(array_filter($empty_array)) ) $errors .= 'You must enter a value for each required field.<br />';



    //********************
    //Display the errors.
    //********************
    if ($errors) echo '<h3>Oops..</h3>'. $errors; var_dump($args); die;

}

}

然后我这样称呼它：

$Validate->validate( array('empty' => $display_name, 'empty' => $password, 'empty' => $password_again, 
'empty' => $gender, 'empty' => $month, 'empty' => $day, 'empty' => $year, 'email' => $email, 'letters' => $gender,
'numbers' => $month, 'numbers' => $day, 'numbers' => $year) );

但我的结果是这样的：

array(4) { ["empty"]=> string(4) "2013" ["email"]=> string(0) "" ["letters"]=> string(0) "" ["numbers"]=> string(4) "2013" }

有什么帮助吗？

array('empty' => $display_name, 'empty' => $password, 'empty' => $password_again, 
'empty' => $gender, 'empty' => $month, 'empty' => $day, 'empty' => $year, 'email' => $email, 'letters' => $gender,
'numbers' => $month, 'numbers' => $day, 'numbers' => $year)

这不是一个有效的哈希。键必须是唯一的。

但是，您可以通过以下方式：

array(
array('empty' => $display_name),
array('empty' => $password),
array('empty' => $password_again),
array('empty' => $gender), ...
)

并适当地修改你的循环。

文档： http: //php.net/manual/en/language.types.array.php

如果数组声明中的多个元素使用相同的键，则仅使用最后一个，因为所有其他元素都将被覆盖。

您不能重用数组中的键。最后一个键值对将覆盖之前的所有键值对。

写一个数组，如：

$Validate->validate(array(
    'empty' => array($display_name, $password, $password_again, $gender, $month, $day, $year, $email),
    'letters' => array($gender, $month),
    'numbers' => array($day, $year).
));

并适当地解析它：

if (isset($args["key"])) {
     foreach ($args["key"] as $value) {
         // ...
     }
}
// and this for every method to check
