如何自动将十进制转换为数字而不是PHP中的字符串？

Question

How to make auto convert a decimal data type into number not a string in php?

I changed data field into decimal(4,2) from double. I have many checks like

if ($row->field)

And $row->field === 0.00. When it was double it's ok. But when I get decimal in php it's get string type and '0.00' it's TRUE.

"Add (float) before $row->field" are not my way, because I change many field and too many places where I use it.

I want find a better way, than change too many lines of code. Maybe some extensions or something else.

Why not return a boolean expression from MySQL itself as part of your query?

SELECT decimal_column <> 0.00 as bool_expression FROM table;

Then test the expression like: if($row->bool_expression)
