Question

round() function is used for decimal like 5,5 -> 6 and 5,3 -> 5, and i have problem with milion numbers. For Example : i have number like 35000001, how to make that number to be 3500000 and 69999 to be 70000

Answer 1

$a = round($a / 10) * 10

您可以将10更改为100、1000，以此类推，以便更大程度地取整。

Answer 2

Take a look at the round function in the PHP manual :

<?php
    echo round(3.4);         // 3
    echo round(3.5);         // 4
    echo round(3.6);         // 4
    echo round(3.6, 0);      // 4
    echo round(1.95583, 2);  // 1.96
    echo round(1241757, -3); // 1242000
    echo round(5.045, 2);    // 5.05
    echo round(5.055, 2);    // 5.06
?>

Perhaps what you want is:

echo round(1241757, -3); // 1242000
