<para>
|
|
<function>maxdb_stmt_bind_param</function> is used to bind variables for the
|
|
parameter markers in the SQL statement that was passed to
|
|
<function>maxdb_prepare</function>.
|
|
The string <parameter>types</parameter> contains one or more characters which specify
|
|
the types for the corresponding bind variables.
|
|
</para>
|
|
<para>
|
|
The extended syntax of <function>maxdb_stmt_bind_param</function> 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 <function>maxdb_stmt_bind_param</function>, it has to be initialized as an emtpy
|
|
array. See the examples how to use <function>maxdb_stmt_bind_param</function> with extended syntax.
|
|
</para>
|
|
<para>
|
|
Variables for SELECT INTO SQL statements can also be bound using <function>maxdb_stmt_bind_param</function>.
|
|
Parameters for database procedures can be bound using <function>maxdb_stmt_bind_param</function>. See the
|
|
examples how to use <function>maxdb_stmt_bind_param</function> in this cases.
|
|
</para>
|
|
<para>
|
|
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
|
|
<function>maxdb_stmt_bind_param</function>.
|
|
</para>
|
|
<para>
|
|
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
|
|
<function>maxdb_stmt_bind_param</function>.
