Question

我使用PHP filter_validate_int执行简单的电话验证。长度应该是10个字符，所有都应该是数字。但是，由于大多数电话号码都以0开头。过滤器验证int函数返回false。无论如何都要解决这个问题。这是我用过的代码

if(!filter_var($value, FILTER_VALIDATE_INT) || strlen($value) != 10) return false;

Answer 1

您无法做任何事情来使此验证工作。在任何情况下，您都不应该使用FILTER_VALIDATE_INT，因为电话号码不是整数;它们是数字字符串。

如果你想确保$tel是一个由10个数字组成的字符串，你可以使用正则表达式：

if (preg_match('/^\d{10}$/', $tel)) // it's valid

或（或许更好）一些oldschool字符串函数：

if (strlen($tel) == 10 && ctype_digit($tel)) // it's valid

Answer 2

您可以使用正则表达式：

if (!preg_match('~^\d{10}$~', $value)) return false;

Answer 3

使用preg_match

$str = '0123456789';

if(preg_match('/^\d{10}$/', $str))
{
    echo "valid
} 
else 
{
    echo "invalid";
}

Answer 4

0不是int的有效起始编号。 0是八进制数的起始数。

电话号码是字符串，而不是int。您必须使用正则表达式来验证它。

Answer 5

可能需要检查返回是否为0。过滤器在验证成功时返回输入，或者在失败时返回false。

使用严格比较（===或！==）进行比较，例如$ result！== false。

if(filter_var($squid, FILTER_VALIDATE_INT)!==false ) {
 //if it's here, it passed validation
}

您还可以使用is_numeric函数： http://php.net/manual/en/function.is-numeric.php

Answer 6

这是一个PHP错误-#43372

正则表达式很好，但是会消耗一些资源。

此方法适用于任何整数，包括零和前导零
