PHP - Is This A Good Use For Anonymous Functions?
I've always had an issue needing to write and maintain script to validate both client side and sever side so a while back I wrote a validation class whose primary purpose was: Accept in its constructor a JSON string which is mostly identical to the jQuery validation option except it also included a "sanitize" property. For instance: {"rules": {"account": {"minlength": 6}}, "messages": {"account": {"minlength": "Six numbers are required"}, "sanitize":{"account":int}}. Provide the correct jQuery validation option so a form can be validated client side. Sanitize the form data server side. Validate the form data server side.I recently looked at the code and it is a train wreck. I used a single class and had a bunch of protected functions where some would validate per a given rule and return the message upon error and others would sanitize. For non-typical rules required by the specific application, I would extend the class and add them. Some of these added rules required other resources such as an entities primary key, a PDO connection, etc. While inheritance worked fine to add simple rules, it did not do so for the rules which needed other resources. Also, even though I used "final" on my base class methods, I never liked this single class of many methods as I couldn't use the same name for a given rule and sanitize method (i.e. would rather use digit and digit instead of digit and int). I am thinking of changing it to something like the following. While this is definitely better, I question whether I should be using traditional classes to define my standard and custom rules. Any recommendations? Thanks
class Validator
{
protected $options,
$rules=[
"digit"=>function($value, $prop, $name){
return /*validate and return error string or null*/;
},
"minlength"=>"ect, etc"
];
public function __construct(string $json, \Closure ...$customRules=[]) {
$this->options=json_decode($json);
$this->rules=array_merge($this->rules, $customRules);
}
}
class Application
{
public function someMethod() {
$pdo=$this->pdo;
$applicationCustomRules=[
'someCustomRule'=>function($value, $prop, $name) use ($pdo) {
return /*validate and return error string or null*/;
}
];
$validator=new Validator($json, ...$applicationCustomRules);
//Which can be used such as:
$jQueryOptions=$validator->getJQueryOptions();
$validator->validate($data);
$validator->validateProperty('account', $account);
}
}
Similar TutorialsI have built a small classified ads application. A person can put in an item for sale and it will diaplay the item. On the input form for the ad they enter their email address.
I am looking for an application that will display an anonymous email address on the classified ad and send to the anonmmous email through to their real email address. I would prefer to do this through the web server of the client and not have to set up a Google Apps or third party email accout for the "catch all" account.
Any recommendation for tutorials to explain and illustrate how to write this code.
Thanks in advance for any assist.

When using the phpDoc PHAR to parse the following file, it returns Parse Error: Syntax error, unexpected '(' on line 16 No summary was found for this file, and doesn't include the file. The specific script which triggers the error is ($this->prototype)(). I am using the PHAR listed on https://www.phpdoc.org/ which appears to be the same as https://github.com/phpDocumentor/phpDocumentor2/releases/download/v2.9.0/phpDocumentor.phar, and am running PHP 7.1.26. Any guess why I am getting this error? Recommended workarounds? As a hack, I am thinking of adding an ignored function or class who's only missing is to invoke the anonymous function. I've also tried using the PHAR at https://github.com/phpDocumentor/phpDocumentor2/releases/tag/v3.0.0-alpha.3, and while I don't get this error, I don't get any output. I first tried it without downloading the public key but got ssl errors. Is there more to in than just locating the two files in the same directory? Thanks

I am trying to run the function "age", using the last line, I thought that is how I could to access that method, but that doesn't work. Code: [Select] <?php require_once '../phpLive/phpLive.php'; $live->myClass = (object)array( "name" => "Billy Bob Joe", "age" => function($dob){ // Run some code } ); echo $live->myClass->age("1986-07-22"); ?> I get the following error when trying to do that. Quote Fatal error: Call to undefined method stdClass::age() in /xxx/new.plugin.php on line 9 Any Ideas how I can access that method? Thanks! So I have made an anonymous poll system but I would like to limit the possibility to vote only once from a single pc. I think that I could store and check 3 things regarding a user that has voted: 1) $_SERVER['HTTP_CLIENT_IP']."!".$_SERVER['HTTP_X_FORWARDED_FOR']."!".$_SERVER['REMOTE_ADDR']; 2) HTTP cookie 3) Flash cookie LSO (because this contrary to the HTTP cookei can be detected in multiple browsers( (only if Flash is installed))) But there can be a simple situation - a simple user votes one time from Firefox and after a time his IP changes (for example he uses some Mobile internet where dynamic addressing is used) . Then for some reason he wants to use Internet Explorer where Flash is not installed. In result - it is possible to vote twice. Can anyone please suggest something regarding this? I know there is not 100% bulletproof solution - I just want to minimise the possibility to vote more than once. Also I am thinking about using EverCookie(undeletable cookie) but that could cause a lot of other problems. I have a script I am putting together that simulate a cricket game. The only issue is, that there are a huge number of functions because there doesn't seem to be any other way to do this properly. As well as this, there a while() loop and all this seems to be leading to the page reaching a max 30 second timeout when generating the result. My code is attached below, it is quite messy at the moment because i've just be working on it, but I was wondering if anyone has any solutions of how I can speed this up or change to prevent a timeout: <?php // Error reporting error_reporting(E_ALL);

I am trying to do something like this: Code: [Select] class my_class { function one () { $two = two (); $three = three (); $five = $two + $three; return $five; } function two () { $two = 2; return $two; } function three () { $three = 3; return $three; } } Unfortunately, I keep getting an error message saying that my call to two () is an undefined function. I am gathering from this that the scope of one () is not aware of the existence of two (). Is there a way to get around this so I can call two () and three () from one ()? I was wondering if this is faster or better performance. Each time a user submit's a post on my forum I will make it +1 the .txt file on my main server directory called test.txt, then I can just call that on my main forum index to show the amount of total posts our board has, instead of using mysql queries to sum all of it from the tables... good idea? or am i retarded? I have a SQL statement which is difficult to use PDO on, it might not even be possible to do.
So I'm filtering it like this:
$search = $_GET['search'];
$search = preg_replace("/[^A-Za-z0-9]/", " ", $search);
$search = $mysqli->real_escape_string($search);
Will this result in an acceptable level of security?
Edited by anderson_catchme, 16 September 2014 - 12:28 PM. Hey! I was wondering if anyone had a really nice login tutorial that teach to make a secure login that is easy to use. Also, it would be best if it checked the other files as a normal logincheck.php does, but it gotta fit the login of course Anyone ? I'm going to write a script that determines if a proxy is good or not through cURL and I would like to know if anyone knows what qualifies a proxy as being good. Let's assume I need to do some surfing through a proxy - that's it. Is there a way in PHP to determine the 'type' of proxy? For example (elite, codeen, etc.) If the proxy page exists is that all I need to run cURL through it or otherwise consider it as being good? Or should I focus my attention towards simply going through the whole process of getting a 'dummy' page using cURL through the proxy and, should it succeed, it will be considered good. I suppose if I can avoid the latter then the script would be more efficient. Advice and suggestions are always greatly appreciated here. Hi there, I am currently using the in_array() function to check the user's country with the country in the ShippingProfile table. I have a function that returns the shipment profile info from the table. $myshipProfile = filter_shippingprofile(array(......)); And in the $myshipProfile I get the profile info with the countryID. Now I can check the user's country in the array: if(in_array($_SESSION['userCountryId'], $myshipProfile)) { print "yes country is found"; } I works fine so far. But there is a slight problem to it. I did a quick: print_r($myshipProfile); And the output was: Array ( [shippingprofileID] => 14 [supplierId] => 66 [shippingprofilename] => ProfName1 [shippingto] => CustomCountries [ShipRegionCountries] => 66 [shippingcost] => 10 Notice the supplierId and the ShipRegionCountries has the same value. And now when I try to perform in_array() it will return true every time even if the ShipRegionCountries is not 66 because as supplierID is 66. You see the conflict. Therefore, can we write like this: if(in_array($_SESSION['userCountryId'], $myshipProfile['ShipRegionCountries'])) { print "yes country is found"; } I get no ouput for this. Whats the correct way to check only the 'ShipRegionCountries' in the array?

Not just crap ones, like real nice ones. XD Thanks in advance I just made this mini class for hashing passwords, is this all there is to it? Setting a salt string, and hashing the string using something like sha1(md5($salt.$password)) Code: [Select] <?php class MyHash { private $salt = "a6B2yj90sZ34"; public function set_salt($salt){ $this->salt = $salt; } public function hash_string($string){ return sha1(md5($this->salt.$string)); } public function check_hashed_string($user_input, $correct_pass){ if($this->hash_string($user_input) == $correct_pass){ return true; }else{ return false; } } } ?> Let's say for an "entry-income or low-income" to get started with.
How should it look like when it comes to the skills?
Could it work out if somebody for example can program with "bind parameters" and OOP in PHP?
What are your recommendations?
