Find value from multidimensional array from given two values - php

Question

I have the following array.
Array
(
[0] => Array
(
[product] => p1
[item] => q1
[date] => d1
[status] => N
)
[1] => Array
(
[product] => p2
[item] => q2
[date] => d2
[status] => Y
)
[2] => Array
(
[product] => p1
[item] => q3
[date] => d3
[status] => N
)
)
From this array, I want date from above with the given product and value.
For Example, I have product = p2 and item = q2 as a string. Now from this array, I want a date from this array which has product = p2 and item = q2.
So I need output from the above example is: d2
I tried array_column and array_search but can't find value from product and item both.
Please help me out with this in PHP.

Answer 1

You can iterate over your products and check required criteria with if statement.
foreach ($products as $product) {
if ('p2' === $product['product'] && 'q2' === $product['item']) {
var_dump($product['date']);
}
}

Answer 2

The conditions are as a string of type
$strCond = "product = p2 and item = q2";
given?
This is converted into an array which can be processed better:
parse_str(str_replace(' and ','&',$strCond),$cond);
/*
$cond = array (
'product_' => " p2",
'item_' => " q2",
);
*/
array_filter() with a closure which cleverly uses array_intersect_assoc() delivers the result.
$result = array_filter($input,function($row) use($cond){
return array_intersect_assoc($cond, $row) === $cond;
});
Result:
array (
1 =>
array (
'product' => "p2",
'item' => "q2",
'date' => "d2",
'status' => "Y",
),
)
As a rule, with such multidimensional arrays there are always several data records in the result. You can get the date of the first record like this:
$firstDate = reset($result)['date']; //d2
Note: The algorithm was taken from PHP class tableArray.
One way of solving with this class:
$result = tableArray::create($input)
->filterEqual($cond)
->fetchRow()
;
/*
$result = array (
'product' => "p2",
'item' => "q2",
'date' => "d2",
'status' => "Y",
)
*/
