maxdb_stmt_bind_param

(PECL maxdb >= 1.0)

Binds variables to a prepared statement as parameters

bool maxdb_stmt_bind_param ( resource $stmt, string $types, mixed &$var1 [, mixed &$... ] )

Procedural style

Object oriented style

bool maxdb_stmt::bind_param ( string $types , mixed &$var1 [, mixed &$... ] )

Procedural style (extended syntax):

bool maxdb_stmt_bind_param ( resource $stmt , string $types , array &$var )

Object oriented style (extended syntax):

bool maxdb_stmt::bind_param ( string $types , array &$var )

maxdb_stmt_bind_param() is used to bind variables for the parameter markers in the SQL statement that was passed to maxdb_prepare(). The string types contains one or more characters which specify the types for the corresponding bind variables.

The extended syntax of maxdb_stmt_bind_param() allows to give the parameters as an array instead of a variable list of PHP variables to the function. If the array variable has not been used before calling maxdb_stmt_bind_param(), it has to be initialized as an emtpy array. See the examples how to use maxdb_stmt_bind_param() with extended syntax.

Variables for SELECT INTO SQL statements can also be bound using maxdb_stmt_bind_param(). Parameters for database procedures can be bound using maxdb_stmt_bind_param(). See the examples how to use maxdb_stmt_bind_param() in this cases.

If a variable bound as INTO variable to an SQL statement was used before, the content of this variable is overwritten by the data of the SELECT INTO statement. A reference to this variable will be invalid after a call to maxdb_stmt_bind_param().

For INOUT parameters of database procedures the content of the bound INOUT variable is overwritten by the output value of the database procedure. A reference to this variable will be invalid after a call to maxdb_stmt_bind_param().

**Type specification chars**
Character	Description
i	corresponding variable has type integer
d	corresponding variable has type double
s	corresponding variable has type string
b	corresponding variable is a blob and will be sent in packages

Returns:

Returns TRUE on success or FALSE on failure.
