        )

)

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))

Where is your code? StackOverflow is not a code writing service. — Jacob Lambert

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.

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

array_column() is not necessary if you are going to iterate the array anyhow. All eval.in links are now dead.

@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.
