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 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 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 need to extract the value of the attributes of a html tag that is defined as a php variable:
[video src="http://localhost/video.mp4" poster="http://localhost/thumb.jpg" preload="none"][/video]
values of src and poster should be separated and cast to array
if your text is a php variable, you can use preg_match :
<?php
$text = '[video src="http://localhost/video.mp4" poster="http://localhost/thumb.jpg" preload="none"][/video]';
preg_match('/src=\"([^\"]+)\"/si', $text, $src);
preg_match('/poster=\"([^\"]+)\"/si', $text, $poster);
$array['src'] = $src[1];
$array['poster'] = $poster[1];
print_r($array);
?>
also you can use simplehtmldom
You can use an html parser for this. See this one: http://simplehtmldom.sourceforge.net/.
$html = str_get_html('<video src="http://localhost/video.mp4" poster="http://localhost/thumb.jpg" preload="none"></video>');
foreach($html->find('video') as $element)
{
$array['src'] = $element->src;
$array['poster'] = $element->poster;
}

?>
echo $arry. This 1 i want to show [ MAX value position's 01.]. Or someone have better way.
<?php
$arr_numeric= array('41', '112', '25','54');
$max_position = array_search(max($arr_numeric), $arr_numeric);
echo $max_position;
?>
position start from 0.
OUTPUT
1
$arr = array('41', '112', '25','54');
$index = array_search(max($arr),$arr);
echo "MAX value position's".$index;
Similar Question here
I get it with a google search.
$maxs = array_keys($array, max($array))
Note:
this way you can retrieve every key related to a given max value.
If you are interested only in one key among all simply use $maxs[0]

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");
