    [1] => Array
        (

                    [17] => 1
                )

        )

)

这就是我的尝试：

$tmp = array();
foreach($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

试试这个：

foreach ($your_array as $subarr) {
    echo $subarr[package]." minimum = ";
    echo min($subarr[value])." and maximum = ";
    echo max($subarr[value])."<br>";
 }

这将输出每个包名以及最小值和最大值。

Answer 2

@Arebhy Sri，你应该在php中搜索数组，这就像基本问题一样。

$finalArray = [];    
foreach ($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

我使用简单的foreach和数组reset()和end()的两个函数。

reset（）：返回第一个数组元素的值，如果数组为空则返回FALSE。

end（）：返回最后一个元素的值，或返回空数组的FALSE。

Answer 3

只需使用min()和max()功能。

您的代码：

foreach(array_column($array, 'value') as $key => $values){
    echo PHP_EOL . 'SubArray '. $key .' min = '. min($values) . ' and max value = '.  max($values);
}

输出：

SubArray 0 min = 5且max value = 3356143
SubArray 1 min = 1且max value = 2764815
