How to get array values certain condition - php

Question

There is something I want to ask to take the array value based on the biggest score in score keys and the smallest strlen in word keys, this sample array:
<?php
$data = array(
'0' => array('score' => '4','word' => 'titiek'),
'1' => array('score' => '4','word' => 'titik'),
'2' => array('score' => '4','word' => 'titie'),
'3' => array('score' => '3','word' => 'tuatuka'),
'4' => array('score' => '3','word' => 'titiks'),
);
$result = //do something??
print_r($result);
?>
let we see in $data array, condition the biggest score and the smallest strlen we have $data[1] and $data[2], right? but, I need the first queue. the result print_r($result) is a:
Array ( [score] => 4 [word] => titik )

Answer 1

You can use usort to sort your array by score and then word length, and then your desired result will be in $data[0]. Note that we rank equal word lengths higher so that we return the first one of the shortest length that we see in the array.
usort($data, function($a, $b) {
if ($a['score'] == $b['score'])
return (strlen($a['word']) >= strlen($b['word'])) ? 1 : -1;
else
return $b['score'] - $a['score'];
});
print_r($data[0]);
An alternate method (not relying on usort behaviour) is to find the maximum score and then process the array looking for the first, shortest string with that score:
$max_score = max(array_column($data, 'score'));
$minlength = PHP_INT_MAX;
foreach ($data as $key => $value) {
if ($value['score'] != $max_score) continue;
if (strlen($value['word']) < $minlength) {
$minlength = strlen($value['word']);
$index = $key;
}
}
print_r($data[$index]);
Output (same for both):
Array (
[score] => 4
[word] => titik
)

You can use array_reduce and by using ">=" "<=" it will keep the previous value
$result = array_reduce($data, function ($previous, $current) {
return $previous['score'] >= $current['score'] && strlen($previous['word']) <= strlen($current['word']) ? $previous : $current;
});
var_dump($result);

Here is how you can find it:
$data = array(
'0' => array('score' => '4','word' => 'titiek'),
'1' => array('score' => '4','word' => 'titik'),
'2' => array('score' => '4','word' => 'titie'),
'3' => array('score' => '3','word' => 'tuatuka'),
'4' => array('score' => '3','word' => 'titiks'),
);
$maxScore = 0; $minLen = 0;
foreach($data as $key => $arr) {
$score = $arr['score'];
$len = strlen($arr['word']);
if($score > $maxScore) {
$maxKey = $key;
$minLen = $len;
$maxScore = $score;
} else if ($score == $maxScore && $len < $minLen) {
$maxKey = $key;
$minLen = $len;
}
}
var_dump($data[$maxKey]);
I have used var_dump to show the result. $data[$maxKey] is the required result.
