filter-var

问题 i have the following code: $url = "http://icons3.iconfinder.netdna-cdn.com/data/icons/pool/poolbird.png"; if (filter_var ($url, FILTER_VALIDATE_URL) === FALSE) { echo "Invalid Url"; exit; } else { echo "Works!"; } This displays: invalid url (FALSE) for the above url, but not for other simpler urls.

问题 I always use filter_var($var, FILTER, FLAG); when I get data from $_GET, $_POST and so on, but now this data is a JSON string but I didn't find any filter to sanitize JSON.

问题 I'm using PHP 5.3.10. This is the code: <?php $email = "test@example.c"; if (filter_var($email, FILTER_VALIDATE_EMAIL)) echo "Email: ".$email." correct"; else echo "email not correct"; ?> It returns: "Email: test@example.c correct. I think that a top level domain with only one character is not correct (I'm not aware of one-character-length TLD according to this list: http://data.iana.org/TLD/tlds-alpha-by-domain.txt ). So, FILTER_VALIDATE_EMAIL filter is working correctly or not? 回答1:

问题 I want to compare two arrays, one is set by default and another by user input. When I have set a boolean value only in the default so I want to make sure the user won't use string or number. for instance, 'truex' or '1' is not acceptable. Below is my sample of code, $default = array( "randomise" => false, "id" => null ); $config = array( "randomise" => truex ); function process_array($default,$config) { # Loop the array. foreach($default as $key => $value) { if ((filter_var($default[$key],

问题 For the past three months I've been working for an Indian NGO, doing some volunteer work in the field but also trying to improve their website, which needs a ton of work. Recently I've been trying to fix the "subscribe to newsletter" button, which is broken. I used filter_var to filter the email input, but when I tried to test this out I got an error. Then I learned that the web host is still using php version 4.3.2 and register_globals is turned on. I've mentioned that they should upgrade

问题 I wanted to use the php filer_var function but it's returning a wrong result, it seems that it doesn't take into account the range: $v = 54; $int_opts = array ( 'min_range' => 0, 'max_range' => 24 ); if ( filter_var($v, FILTER_VALIDATE_INT, $int_opts) ) echo 'an integer'; else echo 'not an integer'; This shouldn't be an integer as 54 is not between 0 and 24, but it returns true and echoes "an integer". What's the problem here? Thanks. 回答1: The "options" array needs to have a member named

问题 I built a php script to output data posted in a form, but I ran into a problem. The server the website is going to run on, runs PHP 5.1.6. This version of PHP does not support filter_var. I need to know an alternative on short term (preferably yesterday), and can't find something straight forward on Google or Stack Overflow. Mayhap someone here ran into the same issue in the past and has a quick fix for me? This code: $email= filter_var($_POST['email'], FILTER_SANITIZE_EMAIL); $answer= filter

问题 I have very limited experience with PHP and I'm really hoping someone can help me. What I want to do is sanitize/validate the phone number input so that only numbers are allowed. I think I need to use FILTER_SANITIZE_NUMBER_INT but I'm not sure where or how to use it. Here is my code: <?php // Replace the email address with the one that should receive the contact form inquiries. define('TO_EMAIL', '########'); $aErrors = array(); $aResults = array(); /* Functions */ function stripslashes_if

问题 I'm trying to check whether or not an IP address is an internal-only (i.e. private) IP, but I'm getting a curious result: filter_var('173.194.66.94', FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE); // returns 173.194.66.94 filter_var('192.168.0.1', FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE); // returns false filter_var('127.0.0.1', FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE); // returns 127.0.0.1? Surely 127.0.0.1 counts as a private IP? I found this bug report from 2010 which reports
