As @lagbox tried to highlight in a comment, for pivot tables, both relationships should be belongsToMany. Inverse of hasMany is belongsTo.

If one article belongs to many categories, and one category can have many articles, then, ideally, there it should be a many-to-many relationship. The category model should have a belongsToMany relationship with Article model and vice versa. Additionally, there should be a pivot table, article_category. And as many have suggested, you can get articles the belongs to a category by using @foreach($category->articles as $articles)

By setting the $assoc parameter to json_decode to true, we can convert the JSON values into arrays rather than objects, and then iterate through the product_id array, finding matching quantities from the second array:

$j1 = ‘{“1″:”9″,”3″:”7″,”4″:”6″,”5″:”10″,”6″:”8”}’;
$j2 = ‘{“1″:”1″,”2″:”1″,”3″:”1″,”4″:”1″,”5″:”1″,”6″:”7”}’;
$array1 = json_decode($j1, true);
$array2 = json_decode($j2, true);
foreach ($array1 as $key => $product_id) {
$quantity = $array2[$key] ?? 0;
echo “Product $product_id: Quantity: $quantity\n”;
}

echo “Product $product_id: Quantity: $quantity\n”;
}
Output:

Product 9: Quantity: 1
Product 7: Quantity: 1
Product 6: Quantity: 1
Product 10: Quantity: 1
Product 8: Quantity: 7

I’ve done this using a quick addition to the before filter() in my app_controller.php file.

function beforeFilter() {
if ($this->RequestHandler->isMobile()) {
$this->is_mobile = true;
$this->set(‘is_mobile’, true );
$this->autoRender = false;
}
}

Maybe this helps:


new_data = fake_data.columnA.str.split('',n=4, expand=True).drop(0, axis=1)
stats = new_data.apply(pd.Series.value_counts)
stats = stats.apply(lambda x: (x/x.sum())*100).round(2).fillna(0)
print(stats)


Output

1 2 3 4
A 54.54 45.45 0 0
V 0 0 45.45 54.54
X 45.45 54.54 0 0
Y 0 0 54.54 45.45


Threading isn’t available in stock PHP, but concurrent programming is possible by using HTTP requests as asynchronous calls.

With the curl’s timeout setting set to 1 and using the same session_id for the processes you want to be associated with each other, you can communicate with session variables as in my example below. With this method you can even close your browser and the concurrent process still exists on the server.

Don’t forget to verify the correct session ID like this:

http://localhost/test/verifysession.php?sessionid=%5Bthe correct id]

startprocess.php
$request = "http://localhost/test/process1.php?sessionid=".$_REQUEST["PHPSESSID"];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $request);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 1);
curl_exec($ch);
curl_close($ch);
echo $_REQUEST["PHPSESSID"];
process1.php
set_time_limit(0);
if ($_REQUEST["sessionid"])
session_id($_REQUEST["sessionid"]);
function checkclose()
{
global $_SESSION;
if ($_SESSION["closesession"])
{
unset($_SESSION["closesession"]);
die();
}
}
while(!$close)
{
session_start();
$_SESSION["test"] = rand();
checkclose();
session_write_close();
sleep(5);
}
verifysession.php
if ($_REQUEST["sessionid"])
session_id($_REQUEST["sessionid"]);

session_start();
var_dump($_SESSION);
closeprocess.php
if ($_REQUEST["sessionid"])
session_id($_REQUEST["sessionid"]);
session_start();
$_SESSION["closesession"] = true;
var_dump($_SESSION);
