This is what I have tried:
$tmp = array();
foreach($arrayName as $arg){
$tmp[$arg['package']][] = $arg['value'];
}
$output = array();
foreach($tmp as $type => $labels){
$output[] = array( 'package' => $type, 'value' => $labels, );
}
print_r(($output))

Answer 1

Try this:
foreach ($your_array as $subarr) {
echo $subarr[package]." minimum = ";
echo min($subarr[value])." and maximum = ";
echo max($subarr[value])."<br>";
}
this will output each package name together with the minimum and maximum values.

Answer 2

Simply use the min() and max() functions.
Your code:
foreach(array_column($array, 'value') as $key => $values){
echo PHP_EOL . 'SubArray '. $key .' min = '. min($values) . ' and max value = '. max($values);
}
output is:
SubArray 0 min = 5 and max value = 3356143
SubArray 1 min = 1 and max value = 2764815

Answer 3

#Arebhy Sri, You should search about array in php, It's like basic problem.
$finalArray = [];
foreach ($mainArr as $subArr){
$array = $subArr['value'];
sort($array);
$tempArray['minimum'] = reset($array);
$tempArray['maximum'] = end($array);
$tempArray['package'] = $subArr['package'];
$finalArray[] = $tempArray;
}
$finalArray //you can use
I am using simple foreach and two functions of array reset() and end().
reset(): Returns the value of the first array element, or FALSE if the array is empty.
end(): Returns the value of the last element or FALSE for empty array.
