PHP compares Int data in mysql

Source: Internet
Author: User
For example, if a column in a mysql table is of the int (10) type, I obtain such data in php, and then I want to know if the data is a specific value, should I use $ data2 or $ data & quot; 2 & quot ;? When I insert data, it is $ data2. For example, if a column in a mysql table is of the int (10) type, I obtain such data in php, then I want to know if this data is a specific value. Should I use $ data = 2 or $ data = "2 "? When I insert data, it is $ data = 2;

MySQL returns two types of data (text or binary ).$ Data = '2'.

$ A = $ B is equal to TRUE. If $ a is equal to $ B after type conversion. $ A ===$ B all equal to TRUE, if $ a is equal to $ B, and their types are the same.

Since it is an integer, do not enclose it in quotation marks and write it$ Data = 2You can.
