I need to group array results into 4 new arrays. Trying to group each result into the appropriate array like: top 25% mid-top 25% mid-low 25% low 25%
THIS DOES NOT WORK but that's why I'm asking how to go about it.
$top = "70000";
$mid = "40000";
$low = "25000";
$resultsarray = array(100000,75000,55000,50000,20000,5000);
echo "Top 25%:";
foreach ($resultsarray as $value) {
if($value >= $top){
echo $value;
}
}
echo "Mid Top 25%:";
foreach ($resultsarray as $value) {
if($value >= $mid && $value < $top){
echo $value;
}
}
and so on...
array_filter
will give you a smaller array based on the criteria you give.
$top = "70000";
$mid = "40000";
$low = "25000";
$resultsArray = array(100000,75000,55000,50000,20000,5000);
$top25 = array_filter($resultsArray, function ($value) use ($top) {
return $value >= $top;
});
$midTop25 = array_filter($resultsArray, function ($value) use ($top, $mid) {
return $value >= $mid && $value < $top;
});
$midLow25 = array_filter($resultsArray, function ($value) use ($mid, $low) {
return $value > $low && $value < $mid;
});
$low25 = array_filter($resultsArray, function ($value) use ($low) {
return $value <= $low;
});
function printNums(array $arr)
{
return array_reduce($arr, function ($carry, $number) {
return $carry .= $number .= " ";
});
}
printf("Top 25%%: %s\n", printNums($top25));
printf("Mid-Top 25%%: %s\n", printNums($midTop25));
printf("Mid-Low 25%%: %s\n", printNums($midLow25));
printf("Low 25%%: %s\n", printNums($low25));

Replace $numbers
with $resultsarray
. In your previous code, the $numbers
array does not exist.
Let me know if that fixed it for you.
