php条件代码显示与预期不同的结果

Question

This code should print the result in a green color if the condition are true and but instead it is print a blue color [like in the 'else' code]

<?php
$col = null;

$chek = 51200;
$chek -= 5200;

if ($chek / 1000 == 0 && (($chek % 10000) * 2) == 12000) {
    $col = "style='color:green;'";
    $save .= "$co . $a1 * $b1 = $span $col> $l </span> </br> </br>";
} else {
    $col = "style='color:blue;'";
}
$res = "<span $col> $chek </span>";

echo $res;

Answer 1

The problem with this if($chek / 1000 == 0

Because 46000 / 1000 != 0

I think you want to put != rather than ==

I hope i helped you :)
