I need to filter the value like this 100.50 using filter_var in PHP.
Now I am using like thisfilter_var($_POST['amount'],FILTER_SANITIZE_NUMBER_INT) : '';
And it gives me the result is 10050 .
How can I solve this problem.
Thanks in advance.
是否可以使用PHP中的filter_var过滤带小数点的整数？

100.50turning into10050pretty bizarre on PHP's end. WTF?).You would need to use a different filter, e.g.
FILTER_VALIDATE_FLOAT.本回答被题主选为最佳回答 , 对您是否有帮助呢?解决 无用评论 打赏举报 分享
