So, before uploading on the server through cPanel, this code works fine. But on the server, I cannot.

On Server
On localhost

Both the codes are the same. It just doesn’t work on the website server. Please help me.

Here is the code snippet:

PHP CODE (below)

<?php
if(isset($_POST['form1'])) {
    $valid = 1;

    if(empty($_POST['tcat_id'])) {
        $valid = 0;
        $error_message .= "You must have to select a Main Menu<br>";
    }

    if(empty($_POST['mcat_name'])) {
        $valid = 0;
        $error_message .= "Sub Menu can not be empty<br>";
    }

    if($valid == 1) {

        // Saving data into the main table tbl_mid_category
        $statement = $pdo->prepare("INSERT INTO tbl_mid_category (mcat_name,tcat_id) VALUES (?,?)");
        $statement->execute(array($_POST['mcat_name'],$_POST['tcat_id']));
    
        $success_message = 'Sub Menu is added successfully.';
    }
}
?>

Whenever I send more than 1 paralel ajax request at a time to my backend, some respond within a reasonable timeframe (<100ms), however some of the requests hang for approximately 1s before returning a response, regardless of which order they are executed in.

I have decided to test this out by creating a very simple HTML+jQuery/PHP (frontend+backend) script which creates 6 paralel ajax requests and running it both on my local server, as well as Digitalocean’s server using the same setup (Debian 10 Apache + PHP 7.4).

The results on local server:

The results on Digitalocean server:

The javascript:

 function ajaxAtOnce() {
        $.get("ajax1.php", function (data) {
            console.log(data);
        });
        $.get("ajax2.php", function (data) {
            console.log(data);
        });
        $.get("ajax3.php", function (data) {
            console.log(data);
        });
        $.get("ajax4.php", function (data) {
            console.log(data);
        });
        $.get("ajax5.php", function (data) {
            console.log(data);
        });
        $.get("ajax6.php", function (data) {
            console.log(data);
        });
    }

PHP endpoints (all equal):

<?php

    // return 100 randomly ordered numbers
    $array = range(1,100);
    shuffle($array);
    echo json_encode($array);

Important notes

• If I hardcode a large enough “timeout” inbetween ajax requests, I get a response within expected timeframe:

function ajaxWithTimeout() {
        setTimeout(function() {
            $.get("ajax1.php", function (data) {
                console.log(data);
            });
        }, 1000);

        setTimeout(function() {
            $.get("ajax2.php", function (data) {
                console.log(data);
            });
        }, 2200);

        setTimeout(function() {
            $.get("ajax3.php", function (data) {
                console.log(data);
            });
        }, 3500);

        setTimeout(function() {
            $.get("ajax4.php", function (data) {
                console.log(data);
            });
        }, 4700);

        setTimeout(function() {
            $.get("ajax5.php", function (data) {
                console.log(data);
            });
        }, 5900);

        setTimeout(function() {
            $.get("ajax6.php", function (data) {
                console.log(data);
            });
        }, 7100);
    }

• If I send all the requests to the same endpoint (ajax1.php for example), there is no problem

• After some research I found 2 server parameters that seem to be mentioned with regards to this issue, but they are set to their default values, and removing the limit does not have an effect:

  RateLimitInterval=30s, RateLimitBurst=1000

As you can imagine, this issue can be very frustrating, especially when developing a SPA in a JS framework like React, which is where I first noticed the issue.

Hello I have to compare strings with numbers, and I have some issues, I did some dumps to try:

            var_dump((string)$prod->Code);
            echo "<br>";
            var_dump($code);
            var_dump((string)$prod->Code == $code);
            echo "<br>";
            echo "<br>";

I got the following results:

string(4) "0539"
string(5) "00539" bool(true)

Basically “0539” is equal to “00539”

What can I do?

I tried also strcmp, I would expect “0539” to test equal to “0539” but not equal to “00539” AND “00539” to test equal to “00539” but not equal to “0539”

I Developed a website with WordPress.
For several hours now, the customize page of the WordPress template doesn’t load completely and only the site title appears and the tabs are not displayed.
I tested it with another computer, it was ok and it loaded completely, but it doesn’t load with my system; I also completely deleted my browser (google chrome latest version) cache.

What do you think is the problem?

In the services.yaml file, I added guzzle client as a service:

guzzle:
    class: GuzzleHttpClient

In the service class, I try to inject Guzzle:

/**
 *  @var GuzzleHttpClient $httpClient;
 */
protected $httpClient;

public function __construct(GuzzleHttpClient $httpClient)
{
    $this->httpClient = $httpClient;
}

I get the following error:

Cannot autowire service "AppServiceMyService": argument "$httpClient" of method "__construct()" references class "GuzzleHttpClient" but no such service exists. You should maybe alias this class to the existing "guzzle" service.

What am I missing here?

I’m currently making my own practice project in which I’m willing to show all my facebook page posts/feeds on a website based on laravel 9. Is it possible ? How can I achieve that with laravel 9?

I am trying to use composer to install a google client library, but cannot install composer or use php on the command line.

I am using php 8.0.8 with MAMP and it is working fine, so I know it is installed.
If I type php in the terminal, I receive the command not found message. Thinking it could be an environment variable, I have tried navigating to the php folder /Applications/MAMP/bin/php/php8.0.8/lib/php and tried the php command again, but still get the same error

Lets say you have 3 models like this

class User extends AbstractModel {
     protected string $name = 'User';
} 

class Car extends AbstractModel {
     protected int $weels = 4;
} 

class House extends AbstractModel {
     protected string $address = 'Some Street 26a';
} 

then you have a fuctions that returns the 3 models like this

protected function generateModels(): array
{
     $user  = new User();
     $car   = new Car();
     $house = new House();

     return [$user, $car, $house]
}

then you have some tests like this

/**
 * @test
 */
public fuction this_is_some_random_test(): void
{
     [
         $user,
         $car,
         $house,
     ] = $this->generateModels();

     $user->name;
     $address->weels;
     $house->address;

     $result1 = some_function_require_user_model($user);

     //some assertions
}

So how do you need to typehint the functions generateModels() that PHPstan understands that It can be multiple models? cause array<int, mixed> doesnt works array<int, AbstractModel> also not cause it will complain like property $name doesnt exist on AbstractModel and the third is like array<int, User|Car|House> what also doenst seem the works cause you will get the same errors and then the functions says that the Car|House types are now allowed. So how can I type hint it propperly?

The above error appears in PHP 8.0, pointing to the line of code below:

if ( isset( $attachment_metadata['sizes'] ) && count( $attachment_metadata['sizes'] ) && ( isset( $attachment_metadata['sizes'][ $intermediate_size ] ) ) ) {

Section of code for this function:

function wpsc_product_image( $attachment_id = 0, $width = null, $height = null ) {

// Do some dancing around the image size
if ( ( ( $width >= 10 ) && ( $height >= 10 ) ) && ( ( $width <= 1024 ) && ( $height <= 1024 ) ) ) {
    $intermediate_size = "wpsc-{$width}x{$height}";
}

// Get image url if we have enough info
if ( $attachment_id > 0 && ! empty( $intermediate_size ) ) {

    // Get all the required information about the attachment
    $uploads    = wp_upload_dir();
    $image_meta = get_post_meta( $attachment_id, '' );
    $file_path  = get_attached_file( $attachment_id );

    // Clean up the meta array
    foreach ( $image_meta as $meta_name => $meta_value ) {

    // Determine if we already have an image of this size

As still relatively new to php, and still learning, would appreciate any feedback or suggestions on how to overcome this error.

I have removed the ‘.php’ file extension the URL in the .htaccess file, however, it seems to prevent my php code from running.

Could someone please suggest a way that I can get this to work?

I have the following data structure in PHP (shortened for brevity) in the array $job:

(
    [jobid] => 33541166
    [country] => South Africa
    [subcounty] => Somerset West
    [position] => Administrator (R7 500 p.m.)
)

I have the following .htacccess rule:

RewriteRule job/(.*)/(.*)/(.*)$ /info.php?jobid=$1&position=$2&city=$3

This rule intermittently works, but the reason why eludes me. Take the examples below:

https://site.co.za/job/33541166/administrator_r_7_500_pm/somerset_west
https://site.co.za/job/33541166/administrator_r_7_500_px/somerset_west

The job structure in the PHP array is the same for both. The URL is purely cosmetic, really, as the only criteria I use to retrieve the job from the database is the job ID (e.g., 33541168).

As you can see, the first URL has “pm” and the second one has “px”, otherwise they are the same. The first link DOES NOT display the job, redirects to homepage, and the second one DOES display the job correctly, yet, the “px” is not in the position string above.

Then there is a completely different job:

https://site.co.za/job/33541168/receptionist_for_general_practitioner/durban_north

And it works 100% with no anomalies.

The code used to construct the URL to be clicked on the page is this ($jobid is used in $position and $city whenever these fields are not present (historical data issues):

if (!empty($v['position'])) {
    $position = preg_replace("/p{P}/", '', trim($v['position']));
    $position = strtolower(str_replace(' ', '_', $position));
} else {
    $position = $jobid;
}
if (!empty($v['subcounty'])) {
    $city = preg_replace("/p{P}/", '', trim($v['subcounty']));
    $city = strtolower(str_replace(' ', '_', $city));
} else {
    if (!empty($v['country'])) {
        $city = preg_replace("/p{P}/", '', trim($v['country']));
        $city = strtolower(str_replace(' ', '_', $city));
    } else {
        $city = $jobid;
    }
}

And the link is structured as follows:

<a style="color: #ffffff !important;"
   href="<?php echo $fullurl; ?>/job/<?php echo $job['jobid']; ?>/<?php echo $position; ?>/<?php echo $city; ?>">
  <?php echo $job['position']; ?>
</a>

Notes, in case needed:

`$job` is the PHP array containing the entire job particulars, as shown in shortened fashion above,
`$position` and `$city` are the modified strings for use in the URL.

I have initially thought maybe a duplicate ID (even though the DB has autoincrement on the jobid column) or a duplicate description, but that does not appear to be the case. I also considered that the . and the ( and ) in the administrator job position might be causing havoc, but I believe it shouldn’t because of the regex I used in my PHP code. To confirm that, I removed these characters in a test, and still does not work consistently.

Every job I have checked shows the URL to click on in the browser in the correct format, so I do not think the PHP code above is fundamentally flawed, except maybe not optimal.

I do not have access to Apache server logs at this time.

Any ideas will be much appreciated.

I am trying to get the quantity of raw materials along with the raw material id. I send recipe id and in response I am getting array like this

[54,"Vanilla Cake Mix",2000] [126,"Water",1200] [1,"Refined Soyabean Oil",200]

Where 54 is Raw Material ID,
Vanilla Cake Mix is Raw Material Name,
And 2000 is Quantity

How do I access each value of this?

My Jquery code is

      `$.ajax({
        type:"POST",
        url:"api_consumption.php",
        data: "product_recipe_id="+product_recipe_id+"&quantity="+value,
        dataType: "json",
        success: function(html)
        {
          //I want to access the values received in json array format.
        }
      });`

My PHP code is

$array = array($raw_material_id, $raw_material_name, $raw_material_quantity); echo json_encode($array);

I tried the each loop but failed.
