                    [17] => 1
                )

        )

)

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))

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.
