In this tutorial, learn how to get the key of max value in an associative array in PHP. The short answer is: use the PHP max() to find the maximum value and array_search() to get the key of the max value. You can also use the PHP foreach loop or PHP for loop to find the ...
function find_max($array, $maxValue) { foreach ($array as $member) { if (is_array($member)) { $maxValue = find_max($member, $maxValue); } else { if ($member > $maxValue) { $maxValue = $member; } } } return $maxValue; } $array = array( 13, array(10, 4, 111, 3)...

因为你组装数组的时候就没写对啦，往里面放元素为什么要拼接换行符，看下图，上一行是运行正常的结果，下一行就是像你那样错误的结果
$spreadsheet->getActiveSheet()->getCell('E6')->getHyperlink()->setUrl('https://www.helloweba.net'); 使用函数 使用SUM计算B5到C5之间单元格的总和。其他函数同理:最大数(MAX),最小数(MIN),平均值(AVERAGE)。 $spreadsheet->getActiveSheet()->setCellValue('B7','=SUM(B5:C5)'); ...
