### Descrierea

Stil obiect-orientat

mysqli_stmt::bind_result ( mixed `&$var1` [, mixed `&$...` ] ) : bool

Stil procedural

mysqli_stmt_bind_result ( mysqli_stmt `$stmt` , mixed `&$var1` [, mixed `&$...` ] ) : bool

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, ...`.

> Notă:

> 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.

### Parametri

  Numai stilul procedural: Un identificator al declarației întors de mysqli_stmt_init().
