###Simple Advice This is just a reminder. When setting environment variables through **.htaccess**, **CLI** or **dotenv** use `filter_var()` to evaluate a boolean. For example, start the built-in PHP server with these variables: DEBUG=FALSE LOG=TRUE SMS=1 SMTP=0 CONNECT=yes BACKUP=no php -d variables_order=EGPCS -S localhost:8000 And then test through `boolval()`: if you forget to use 1 and 0, then something can go wrong as the variable is evaluated like a string and will always return `TRUE`. By using `filter_var()`, with the appropriate filter to validate boolean, you get more flexibility as it: > returns TRUE for "1", "true", "on" and "yes". Returns …

I found myself starting to answer a question that I have answered many times , so I thought why not making a code snippet and just reference this. This is a short code snippet only to demonstrate how this thing work (with apache and rewrite engine on) , in real life PHP code shouldn't be under the public_html / www folder in any case (with maybe only one exception a index.php that its main task is to include something (or instantiate a class) from the src folder) Lets suppose that you have an example folder under the domain example.com , …

Don't you just get sick of hash algorithms constantly been brute forced or even cracked. Well here is an algorithm I have created in my spare time to help out the little guy who just wants a secure hash. This hashing algorithm uses many different techniques including ones used in sha1 to prevent a reversal algorithm and uses a lot of math to help reduce the speed of brute forcing the algorithm. An example of the brute force done on common algorithms today is like I myself have got a website to brute force sha1, sha256, sha512, md4 and md5. …

I've been playing with PDO and got quite a shock, so I thought I'd run this past you all. I love PDO, and I thought that the "prepare once, execute many" idea behind prepared statements was beautiful. Now previous to using prepared statements, I used to build up a long SQL 'VALUES' clause by looping through an array of "records" to insert, instead of running an INSERT query on every 'record' in the array. Sensible enough. So should I now dump that for "multiple executes" in my array loop? Well I tried. Here's my experience... I'm using a simple 'members' …

Here is a PHP class written for PHP4 and PHP5 that will validate email addresses by querying the SMTP (Simple Mail Transfer Protocol) server. This is meant to complement validation of the syntax of the email address, which should be used before validating the email via SMTP, which is more resource and time consuming.

Hello , today I was developing a short url system and I created this class to help me encode / decode integer (id) to small string. That way for example “Ac” means 3674 . Because I believe that it may be helpful to others too I share it here. Notice that in the constructing string each char can be present only once. Example of usage: $numCode = new Model_Utils_Numcode("4fFiV8kRTvm5MPNDcyO1dg7lr20Qtn3X6pKLZUqaEsxCwubGYIzhSWJojHeA9B"); $num = 3674; $encoded = $numCode->encode($num); echo "<br/> $num encoded = $encoded"; // 3674 encoded = Ac echo "<br/> $encoded decoded = ".$numCode->decode($encoded); // Ac decoded = 3674 Class: class Model_Utils_Numcode …

The following snippet is a simple PHP Pagination Script which I wrote. As far as I know it works fine. It is meant to be used within a class, and I have wrapped in in a class in order to demonstrate it's usage. The example given below will return something similar to the following: Pages: [B][ 1 ][/B] [URL="http://mysite.com/index.php?page=2"]>[/URL] [url=http://mysite.com/index.php?page=3]>>[/url] When there are a sufficient number of pages present, a Last Page link is added. When you navigate away from the first page, a previous page link is added. When you navigate past the second page, a first page link …

When using emails as usernames you want them to be unique over your table, but this can be a problem if you consider a GMail account, because of their [username](https://support.google.com/mail/answer/12096?hl=en) [policy](https://support.google.com/mail/answer/10313?hl=en). They allow: * dots * digits * letters * plus addressing text by using the `+` sign, i.e. `orange+juice@gmail.com` * length between 6 and 30 characters, excluding dots and the appended part But when resolving the username they do not consider: * dots * different capitalization * plus addressing So, when you write to: UserName@gmail.com u.sername@gmail.com user.name+forum@gmail.com .u.s.e.r.n.a.m.e.@gmail.com u.serName+doh@googlemail.com You will always match the same account: username@gmail.com This class …

Here is a simple way to insert into a database that isn't much harder than using string concatenation - which we all know is very dangerous due to SQL injection attacks. Put the code snippet into `database.php`. Now, in a script handling a form post, such as `post_reply.php`: <?php require_once("database.php"); // Get session and post data to insert - no need for mysql_real_escape_string or other escaping // (Note: Passwords should still go through password_hash() or crypt() though!) $member_id = $_SESSION['member_id']; $response_to = isset($_POST['response_to']) ? $_POST['response_to'] : (isset($_GET['response_to']) ? $_GET['response_to'] : ''); $subject = isset($_POST['subject']) ? $_POST['subject'] : ''; $post = …

Hi All, Been a bit bored, so went at it to create a class from some long procedural stuff I found littered in various guises all over the web. The code I used as a base for the class came from [here](http://www.codediesel.com/php/downloading-gmail-attachments-using-php/). As this uses IMAP functions and many of you out there use XAMPP on your local machines, ensure that you enable it in php.ini before testing this script. Search the file for `;extension=php_imap.dll` and take off the preceding semi-colon to leave `extension=php_imap.dll`. Save the file. You then need to restart Apache. Usage is pretty simple - just three …

Hi All, thought I'd pass on a (very) simple password class which is built on the new `password_hash()` and `password_verify()` functions. You will need php 5.5.0+ in order to get this to work. If you're thinking of modifying this and using it in a production site, please check that your host has 5.5.0+, as many do not. To be honest there's not much going on beyond the two functions mentioned, but it can be modified easily to change any validation rules. [VERSION 1.1 with improved validation and rehashing](https://www.daniweb.com/web-development/php/threads/485519/a-simple-password-hash-and-verify-class#post2125105) (as suggested by veedeoo and ~s.o.s~) Comments, improvements etc. most welcome.

The purpose of this class is to be able to create an html form with ease. This is inspired by the form helper in CodeIgniter. This can easily adapt to bootstrap or any css and jquery where id is required. To use this class, we need to include the class provided below. require_once('FormHelper.php'); ## we create an instance of the class $form_create = new FormHelper(); we can also dynamically create <select>, by defining the option items as an array $select_array = array('php','java','html','javascript','python','perl','jquery'); generate the form echo $form_create->form_option('post', 'processor.php', 'myform', 'coolform'); echo $form_create->form_label('Name', 'name'); echo $form_create->form_input('text', 'name', '', 'input_class', 'type your …

Hello All. Been playing around with some linked dropdowns. It seems to be a recurring theme here on DW, so I thought I'd offer this up as a possible solution or for discussion, to see how it could be improved. The premise for this set of linked dropdowns is that it is not dependent on php or Ajax following page load, that is to say, all the data is initially dumped into json format from the database and then everything is left to javascript. I've used jQuery to produce a plugin, but the same functionality is possible with just plain …

Hello Everyone, I wrote this script way back in 2008 as Version1. However, I was forced to forget about this, because it was criticized by many developers with BS, MS, and "Seasoned PHP Developer" under their names. During those days, I couldn't stand up for my own reasons, because I can't even put High School graduate as my lone achievement under my name. I was told this script was 10 steps backward to where we at in 2008. If my memory still served me well, even my own brothers in Silicon Valley have asked me to forget about this. **enough …

This is a function that I wrote and have re-used many times. I share it with you DaniWebers to use, laud or destroy! In a nutshell, this takes a user's search box input phrase and generates a series of LIKE clauses for your SELECT statement. Looks like "col1 LIKE '%s_term1%' OR col1 LIKE '%s_term2%' OR col2 LIKE '%s_term1' .." The column names you want it to use is the second parameter of the function.

This is a function I created to facilitate the sending of PHP emails. Just give it the name and email of who your sending it to, and your name and email. A subject and a message. These options are required. The type, cc and bcc options are optional. By default, the email will be sent as text, so if your sending an HTML email, make sure to set the type to 'html'.

A while ago I explained how you could tag articles (see [this thread](http://www.daniweb.com/web-development/php/threads/387961/php-code-to-show-related-posts-on-a-blog)). Now you get a full working example. This code and the SQL script is also available on GitHub. The attached MySQL dump needs to be imported into your database, and you must update the credentials in the code below. I think the code is short enough to be read without comments. If this is not the case, feel free to ask questions.

Demand: There are some sound systems of cars (products) each of them has an article link and some other details (e.g. Voltage) ,those products can be categorized , so we have categories of them. The categories can have either …
