MySQL uses the bigint field to store the phone 10-digit number, incredibly truncated. What to do with it

MySQL uses the bigint field to store the phone 10-digit number, incredibly truncated.
How do I use the bigint field to store my phone number every time. No matter what the number of 11 digits, all only show 4294967295

------Solution--------------------
Echo Pow (2, 32); 4294967296

That's because you don't have a cell phone number treated as a string in PHP.

------Solution--------------------
The "integer value" type of PHP does not support 11-bit decimal numbers (this is said on a 32-bit operating system).
The "integer value" over the range is converted to "floating point" by PHP.

You have a problem, it is possible that you use some kind of database interface program, this situation has been a special treatment. In short, if you can see the final execution of INSERT into ... Statement, it is clear.
