mysqli_stmt::bind_result -- mysqli_stmt_bind_result — Binds variables to a prepared statement for result storage
Nesne yönelimli kullanım
Yordamsal kullanım
Binds columns in the result set to variables.
When mysqli_stmt_fetch() is called to fetch data, the
MySQL client/server protocol places the data for the bound columns into
the specified variables var1, ....
Bilginize:
Note that all columns must be bound after mysqli_stmt_execute() and prior to calling mysqli_stmt_fetch(). Depending on column types bound variables can silently change to the corresponding PHP type.
A column can be bound or rebound at any time, even after a result set has been partially retrieved. The new binding takes effect the next time mysqli_stmt_fetch() is called.
