$rating = $rowsRaing;
Array
(
[0] => stdClass Object
(
[ratting] => 2.5
)
)
I want rating value.
I want user average number of ratting help me
Thanks
Your query should be
$rowsRaing = $wpdb->get_results("select avg(ratting) as rating from tablename where id='".$_REQUEST['id']."'");
$rat=$rowsRaing;
$RatingVal = $rat[0]->rating;
By using this variable you get the avg number of ratting
"$RatingVal"
It's var of object inside array, so:
$yourRatingValue = $rat[0]->rating;

$matchThese = array('product_id' => 8789, 'MONTH(date_created)' => '04');
$result = ExpiryPrepayment::firstOrNew($matchThese);
$result->payment_status = 1;
$result->save();
***====>'MONTH(date_created)' => '04'***
Help me get condition only month or year in column date_created
Why are you sending an array at a firstornew? This is basically a string that you are building an array with in the eloquent. Inserting an array will not work. Really the product_id should be a unique so you only need that value in your where.
So it would be something like this...
firstOrNew(['product_id' => $product_id]);
$product_id being the variable of the unique id.
Then if you have tons of products to add just loop over the array of product ids and it will either make a new row at your save or update the product when it finds it first.

I'm making simple test script with PHP+mysql.
The script gives the question and SELECT with 4 options (answers).
1 of them is correct, 3 others are incorrect, retrieved from mysql table.
I have 4 variables and all works fine, but I need to retrieve these variables in random order.
$variable1='1';
$variable2='2';
$variable3='3';
$variable4='4';
Just need some direction what to learn, what method to use.
Many thanks in advance
SELECT data from MySQL
Store in an associative array
shuffle the array
http://codepad.org/6R9LsGIy
<?php
$arrAnswers = array("a", "b", "c", "d");
shuffle($arrAnswers);
print_r($arrAnswers);
/* Example Ouput:
Array
(
[0] => b
[1] => d
[2] => a
[3] => c
) */
As you've said you have these variables;
$variable1='1';
$variable2='2';
$variable3='3';
$variable4='4';
$arrAnswers = array($variable1,$variable2,$variable3,$variable4);
There are more elegant ways, but with the information given, this is the best I can do :)

When I do a print_r I get this array:
Array (
[0] => Array (
[id] => 5280
)
)
How can I access the id value with PHP?
You can access it like this
$id_value = $your_array[0]['id'];
Try
$mapped = array_map("current",$array);
echo $mapped[0];
This is useful if you have multiple arrays on the root array
eg: Array(Array(),Array()..)
