The content of this article is about the solution to the distortion of converting float to int in PHP. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

I encountered a problem at work:

The return value after payment is in cents, and the database uses yuan as the unit, so float is used;

For example, when it is returned, it is 3980, and the database data is 39.80. If you directly multiply this data by 100, it will become 3980;

I checked online and found that PHP has a weak type in float. For integers or after operations The result is a floating point number of an integer.

php can treat it as an integer, but the type remains unchanged. But if it is not an integer after operation, then PHP will treat the result as a strict floating point number.

Solution:

Use round before using intval

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.
