The phpmysqlupdate statement can insert numbers normally, but cannot contain letters or Chinese characters.

Php and mysql are used in combination. the operations on numbers are completely correct. The table attribute in the database is varchar, and the database is also setutf8. but the problem should not be here, not just Chinese characters, no English letter is required. if one row of the six columns is not a number, the update will not fail, but all columns will become null. the update statement is as follows: $ query & quot; updateusersetFirstname & #39; & quot ;. $ _ GET [Firstname]. & quot; & #39;, Lastname & #39; & quot ;. $ _ GET [Lastname]. insert number phpupdate
