I am trying to count the records in the table, but it's showing me nothing in the response, I am working on an API, can anybody help please ?
public function devicesCount()
{
$x = Device::count();
if ($x) {
return ['devices' => $x];
} else {
return ['message' => 'ranii karrezt ydyyyyyyk'];
}
}
use $x = Device::all()->count(); in place of $x = Device::count();
or use Laravel Aggregates like
$count = DB::table('devices')->count();

I keep json data from database. I want to sync with the name that comes with the post and get the price of the data I sync. How can I do that?
$video_tkn = "3D";
$reklam_json = json_decode($siteayar->reklam_json);
$video = json_decode($reklam_json->video);
$video_arr = array();
foreach ($video as $v) {
if ($v->video_tur==$video_tkn) {
$video_arr[] = $v->fiyat;
}else{
$video_arr[] = 0;
}
}
print_r($video_arr[0]);
//Output : 0
//$reklam_json->video
[
{
"video_tur":"2D",
"fiyat":"20"
},
{
"video_tur":"3D",
"fiyat":"80"
}
]
You can do something like. The problem with the code that you have written is that in the $video_arr[0] it is always writing 0 as per your else condition because $video_tkn= "3D" value is in second index in the array $video
<?php
$video_tkn = "3D";
$reklam_json = json_decode($siteayar->reklam_json);
$video = json_decode($reklam_json->video);
$video_arr = array();
foreach ($video as $v) {
if ($v->video_tur==$video_tkn) {
$video_arr[] = $v->fiyat;
}
}
print_r($video_arr[0]);

I execute on my main page some php code which includes :
foreach ($fbdata->feed->data as $fbpost)
{
...
}
How can we convert this , into a loop that goes from (i to z)(0 to 10) ?
Simple for loop
for($i = 0; $i < 10; $i++) {
$fbpost = $fbdata->feed->data[$i];
...
}
or if you like to use the as, try using a foreach but slicing the array before using it
$fbPosts = array_slice($fbdata->feed->data, 0, 10);
foreach($fbPosts as $fbpost) {
...
}

I ask a candidate : What do you like ?
His answer is an array [Math,Physics,Chemistry,IT,Sports]
I do have a list :
Software Analyst : [Math,IT,Programing,Stress,Computer]
Truck drive : [Sports,Driving,Traveling,Exchange]
Physic-chemistry teacher :[Math,Physics,Chemistry,Teaching]
What is the best way in PHP to get the jobs with the maximum common tags with the user input?
You use array_intersect() to find the common tags, then compare among the returned tags amount.
$jobs = array(
'software' => array('Math','IT','Programing','Stress','Computer')
'truck' => array('Sports','Driving','Traveling','Exchange')
'physic' => array('Math','Physics','Chemistry','Teaching')
);
$user_tags= array('Math','Physics','Chemistry','IT','Sports');
$max_common = 0;
$desired_job = '';
foreach($jobs as $key=>$job) {
$common = count(array_intersect($job,$user_tags);
if(max_common < $common) {
$desired_job = $key;
$max_common = $common;
}
}

I am writing a program in which I want to plus two functions together and in the end I want to calculate the total. if anyone can help with this it will be appreciated.
const PRICE_OF_Big_Mac = 2.50;
public $Big_Mac = 0;
public function calculate_dinein_price(){
$dine = 0.00;
$dine += $this->Big_Mac * self::PRICE_OF_Big_Mac;
return $dine;
}
public function calculate_dinein_total(){
$total_dine = 0.00;
$total_dine = $total_dine + $dine;
return $total_dine;
}
but this doesn't work.
You can't access $dine in your second function because it's nowhere defined. The $dine from your first function is only a local variable.
I would suggest this solution which uses the fact that calculate_dinein_price() also returns the value of $dine:
public function calculate_dinein_total(){
$total_dine = 0.00;
$total_dine = $total_dine + $this->calculate_dinein_price();
return $total_dine;
}

i'm trying to do a simple condition check like:
$test = 1;
$test_ = $test==-1?"Test--1":$test==1?"Test-1":$test==0?"Test-0":"Test";
echo $test_;
The output is Test-0 but must be Test-1.
Which could be the problem?
Try this : Put brackets for conditions.
$test = 1;
$test_ = ($test==-1)?"Test--1":($test==1?"Test-1":($test==0?"Test-0":"Test"));
echo $test_;
output :
Test-1
change this
$test_ = $test==-1?"Test--1":$test==1?"Test-1":$test==0?"Test-0":"Test";
to
$test_ = $test==-1?"Test--1":($test==1?"Test-1":($test==0?"Test-0":"Test"));
working example http://viper-7.com/msuCyk
// output Test-1
Ternary operator in PHP is left to right, therefore, its executed like this:
$test_ = (( ( $test==-1 ? "Test--1" :$test==1) ? "Test-1":$test==0)?"Test-0":"Test");
