If I have an array like this:
$cars = array (
array("name"=>"jeep","Year"=>"2012"),
array("name"=>"ferrari","Year"=>"2017"),
array("name"=>"jaguar","Year"=>"2013")
);
How to print a $cars['name'] where $cars[Year] = 2013, is that possible in the array as we can do in MySQL? As we know with MySQL we can do:
select * from table where //condition
So, how this can be done in arrays?

Answer 1

You could loop through each element in the array and using an 'if' statement echo the name of the car if the year is 2013
$cars = array (
array("name"=>"jeep","Year"=>"2012"),
array("name"=>"ferrari","Year"=>"2017"),
array("name"=>"jaguar","Year"=>"2013")
);
foreach ($cars as $value) {
if($value[Year] == 2013){
echo $value[name] ."<br>";
}
}

Answer 2

And also solution with array_filter, because you will probably have multiple cars with same year.
$cars = array (
array("name"=>"jeep","Year"=>"2012"),
array("name"=>"ferrari","Year"=>"2017"),
array("name"=>"jaguar","Year"=>"2013")
);
$filtered_cars = array_filter($cars, function ($item) {
return $item['Year'] === '2013';
});
print_r(current($filtered_cars)['name']);

Answer 3

An example with the isFromYear function accepting the year as a parameter:
<?php
$cars = array (
array("name"=>"jeep","Year"=>"2012"),
array("name"=>"ferrari","Year"=>"2017"),
array("name"=>"jaguar","Year"=>"2013")
);
class YearFilter {
private $year;
function __construct($year) {
$this->year = $year;
}
function isFromYear($i) {
return $i["Year"] == $this->year;
}
}
$matches = array_filter($cars, array(new YearFilter("2013"), 'isFromYear'));
print_r($matches);
?>

Answer 4

You can use array_filter() and pass an conditional function as the second argument along with your array. As an example in your case:
function filterArray($value){
if($value['Year'] == "2013")
return $value['name'];
}
$filteredArray = array_filter($fullArray, 'filterArray');
So if we passed an array that looks like:
$fullArray = array (
array("name"=>"John","Year"=>"2012"),
array("name"=>"Doe","Year"=>"2017"),
array("name"=>"Martin","Year"=>"2013")
);
Output would be:
Array
(
[2] => Array
(
[name] => Martin
[Year] => 2013
)
)
