I have a multidimensional array and I want to change it to my final array. Below is the array I have.

$test = array(
            array(
                "supplier" => "TEST DEPO",
                "rolanID" => array(123, 234, 456),
                "itemCount" => 3
            ),
            array(
                "supplier" => "ANOTHER DEPO",
                "rolanID" => array(123, 786, 345),
                "itemCount" => 3
            ),
            array(
                "supplier" => "ROLAN",
                "rolanID" => array(123, 234),
                "itemCount" => 2
            ),
            
        );

So, with this array I want to output like the below array.

As we can see, if all rolanID is equal to one of the supplier then I don’t want to add that array into the final array.

For, an example the supplier “ROLAN” array is removed completely in the final array as its all rolanID is in the supplier “TEST DEPO” but the supplier “ANOTHER DEPO” has some rolanID that is not in the supplier “TEST DEPO” so, it is included that in the final array.

Array
(
    [0] => Array
        (
            [supplier] => TEST DEPO
            [rolanID] => Array
                (
                    [0] => 123
                    [1] => 234
                    [2] => 456
                )

            [itemCount] => 3
        )

    [1] => Array
        (
            [supplier] => ANOTHER DEPO
            [rolanID] => Array
                (
                    [0] => 786
                    [1] => 345
                )

            [itemCount] => 2
        )

)

So I have two arrays with some ids. I want to sort the arrays in a way that same value elements in array2 must be at the same index as in array1.
For example:

array1 = ['b','a','c','d'];
array2 = ['d','a','c','b'];

After the sort array2 should become like array1 => ['b','a','c','d']
Is there any function in Php? Thanks in advance 🙂

I am using the code below to send a link to the user email to reset the password, the code works fine and sends the link. The problem is after sending the link the page will show many lines of information and a success message at the end.

What is wrong with the code below to avoid these lines? Here is the code:

<?php
    use PHPMailerPHPMailerPHPMailer;
    use PHPMailerPHPMailerSMTP;
    use PHPMailerPHPMailerException;

    require 'PHPMailer/src/Exception.php';
    require 'PHPMailer/src/PHPMailer.php';
    require 'PHPMailer/src/SMTP.php';

    require 'database.php';

    if(isset($_POST["email"])){
        $emailTo = $_POST["email"];

        $code = uniqid(true);
        $sql = "INSERT INTO reset(code, email) VALUES('$code', '$emailTo');";
        $run = mysqli_query($conn, $sql);
        if(!$run){
            exit("Error");
        }

        $mail = new PHPMailer(true);

        try {
            //Server settings
            $mail->isSMTP();
            $mail->SMTPDebug = 2;
            $mail->Host       = 'smtp.gmail.com';
            $mail->SMTPAuth   = true;
            $mail->Username   = 'myEmail.com';
            $mail->Password   = 'xxxxxxxxx';
            $mail->SMTPSecure = 'tls';
            $mail->Port       = 587;

            //Recipients
            $mail->setFrom('myqmial.com', 'Hello');
            $mail->addAddress($emailTo);
            $mail->addReplyTo('[email protected]', 'No reply');

            // Content
            $url = "http://" .$_SERVER["HTTP_HOST"] . dirname($_SERVER["PHP_SELF"]) . "/resetPassword.php?code=$code";
            $mail->isHTML(true);
            $mail->Subject = 'Reset Password';
            $mail->Body    = "<h1>You asked to reset your password، </h1>
                                Click <a href='$url'>this link</a> Please click on the link";
            $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

            $mail->send();
            echo 'The link has been successfully sent to your email';
            
        } 
        catch (Exception $e) {
            echo "Message could not be sent. Mail Error: {$mail->ErrorInfo}";
        }
        exit();
    }
    
?> 
<form method='POST'>
    <input type='text' name='email' placeholder='Email'>
    <input type='submit' name='submit' value='Reset password'>
</form>

I am attaching an image with the results:

I do not know what mistake I am doing, so how can I just show the message (The link has been successfully sent to your email) without all these lines?

I have a very simple MVC project (no DB) that works very well when I launch it with a local server (“php -S localhost:8000 -t public”).

I use my routing this way:

require "Controllers/AppController.php";

$parsed_url = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);
$appController = new AppController();

switch ($parsed_url) {
    case '/':
    case '/home':
        $appController->home();
        break;
    case '/about':
        $appController->about();
        break;
    case '/achievements':
        $appController->achievements();
        break;
    case '/contacts':
        $appController->contacts();
        break;
    default:
        $appController->pageNotFound();

I deployed it with Heroku, adding a Procfile, as specified in the official documentation, but now I can only get the homepage of my portfolio. All my other links throw me a “Not Found – The requested URL was not found on this server.”.

Here’s my Heroku log, if that can help:

2022-10-30T09:26:48.666806+00:00 heroku[router]: at=info method=GET path="/about" host=alexis-boucherie-devweb.herokuapp.com request_id=0dd695f8-8252-4cd4-8d3d-e012daf06130 fwd="86.213.16.43" dyno=web.1 connect=0ms service=1ms status=404 bytes=360 protocol=https

What I don’t understand, is that if I try to var_dump my “$parsed_url”, it does return a “/”, for the homepage. So I think it means the program goes through my Switch Case and that my Controller is ok. Also, because I have my homepage showing in the first place.

I tried to modify the page my $appController object calls for, and by doing so, I can access another page. But then again, if I click on any link or manually type the address of one of my pages (for instance “/contacts”), it doesn’t work.

In the end, I tried and searched for other topics related to this, found two here on StackOverflow, about adding an .htacess file, but I’m not sure I’m getting how that really works. Could this be the real source of my problem?

I’m trying to fill table with values which I’m getting from the database but when I loop though array some values are getting out of the table.

DB values image:

$result = $this->db->query($query)->result_array();

$data['data'] = $result;

Submitting for booked time. Add 5 variable at once. Each time has idVenue, idField, date, time and price.

Question: How can we get all of the times selected in an array of arrays?

booked[0] => Array (
  ["idVenue"] => "id Venue",
  ["idField"] => "id Field",
  ["date"] => "date selected",
  ["time"] => "time selected",
  ["price"] => "price selected"

  ["idVenue"] => "id Venue",
  ["idField"] => "id Field",
  ["date"] => "date selected",
  ["time"] => "time selected",
  ["price"] => "price selected"
), 
... 

Code

<input type="hidden" name="idVenue" value="<?=$getTimes['idVenue']?>">
<input type="hidden" name="idField" value="<?=$getTimes['idField']?>">
<input type="hidden" name="date" value="<?=date('Y-m-d',strtotime($getTimes['date']));?>">
<input type="hidden" name="price" value="<?=$getTimes['price']?>">
<input name="time" value="<?=$getTimes['start']?>" type="checkbox">

Thanks in advance for your time.

I’ve revised namespaces, also reloaded and restarted docker container.

Today, I was trying to understand how the primitive type ‘String’ is implemented in PHP. In search of the same I come across following text from the PHP Manual

The string in PHP is implemented as an array of bytes and an integer
indicating the length of the buffer. It has no information about how
those bytes translate to characters, leaving that task to the
programmer. There are no limitations on the values the string can be
composed of; in particular, bytes with value 0 (“NUL bytes”) are
allowed anywhere in the string (however, a few functions, said in this
manual not to be “binary safe”, may hand off the strings to libraries
that ignore data after a NUL byte.)

After reading above text from the PHP Manual following questions come to my mind :

1. What does it actually mean by an array of bytes and an integer indicating the length of the buffer? What does actually mean by the term ‘buffer’ in this case?

2. Why does PHP not handle the task of translating those bytes to characters by itself? Why and what programmer supposed to do in this case of translation?

3. According to the PHP Manual, there are no limitations on the values the string can be composed of. Does it mean that PHP uses Unicode(utf-8) for the purpose of character encoding?

4. Do string and byte(a unit of digital information that most commonly consists of eight bits) mean the same thing in PHP?

Someone please clear my above doubts with the help of suitable and easy to understand example/s.

Thank You.

I am trying to make a Linkedin Hashtag Generator tool . But I could not find any way to scarpe the suggested hashtags from the Linkedin . I am willing to scrape or get the the data from Linkedin just because I want to maintain the relevancy of the keyword.

I could not find any way to solve it.

So this contact form used to work, however now it loads and says mail sent when someone clicks submit but I never get any emails, what am I missing out?

<?php

// Replace this with your own email address
$siteOwnersEmail = '[email protected]';


if($_POST) {

   $name = trim(stripslashes($_POST['contactName']));
   $email = trim(stripslashes($_POST['contactEmail']));
   $subject = trim(stripslashes($_POST['contactSubject']));
   $contact_message = trim(stripslashes($_POST['contactMessage']));

   // Check Name
    if (strlen($name) < 2) {
        $error['name'] = "Please enter your name.";
    }
    // Check Email
    if (!preg_match('/^[a-z0-9&'.-_+]+@[a-z0-9-]+.([a-z0-9-]+.)*+[a-z]{2}/is', $email)) {
        $error['email'] = "Please enter a valid email address.";
    }
    // Check Message
    if (strlen($contact_message) < 15) {
        $error['message'] = "Please enter your message. It should have at least 15 characters.";
    }
   // Subject
    if ($subject == '') { $subject = "Contact Form Submission"; }


   // Set Message
   $message .= "Email from: " . $name . "<br />";
    $message .= "Email address: " . $email . "<br />";
   $message .= "Message: <br />";
   $message .= $contact_message;
   $message .= "<br /> ----- <br /> This email was sent from your site's contact form. <br />";

   // Set From: header
   $from =  $name . " <" . $email . ">";

   // Email Headers
    $headers = "From: " . $from . "rn";
    $headers .= "Reply-To: ". $email . "rn";
    $headers .= "MIME-Version: 1.0rn";
    $headers .= "Content-Type: text/html; charset=ISO-8859-1rn";


   if (!$error) {

      ini_set("sendmail_from", $siteOwnersEmail); // for windows server
      $mail = mail($siteOwnersEmail, $subject, $message, $headers);

        if ($mail) { echo "OK"; }
      else { echo "Something went wrong. Please try again."; }

    } # end if - no validation error

    else {

        $response = (isset($error['name'])) ? $error['name'] . "<br /> n" : null;
        $response .= (isset($error['email'])) ? $error['email'] . "<br /> n" : null;
        $response .= (isset($error['message'])) ? $error['message'] . "<br />" : null;

        echo $response;

    } # end if - there was a validation error

}

?>
 

And this is the contact form:

<form name="contactForm" id="contactForm" method="post" action="mail/mail.php">

                              <div class="s-loader">
                                    <div class="bounce1"></div>
                                    <div class="bounce2"></div>

                   </div>

                </fieldset>
            </form>

All the messages work, am I missing out on some SMPT information or something? Are there any alternatives to using phpmailer for this job?
