<span class="function"><strong>maxdb_stmt_bind_param()</strong></span> is used to bind variables for the

parameter markers in the SQL statement that was passed to
|

<span class="function"><a href="maxdb_prepare.html" class="function">maxdb_prepare()</a></span>.
|

The string <code class="parameter">types</code> contains one or more characters which specify

the types for the corresponding bind variables.

The extended syntax of <span class="function"><strong>maxdb_stmt_bind_param()</strong></span> 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 <span class="function"><strong>maxdb_stmt_bind_param()</strong></span>, it has to be initialized as an emtpy
|
||
array. See the examples how to use <span class="function"><strong>maxdb_stmt_bind_param()</strong></span> with extended syntax.

</p>
|
||
<p class="para">
|

Variables for SELECT INTO SQL statements can also be bound using <span class="function"><strong>maxdb_stmt_bind_param()</strong></span>.
|
||
Parameters for database procedures can be bound using <span class="function"><strong>maxdb_stmt_bind_param()</strong></span>. See the
|

examples how to use <span class="function"><strong>maxdb_stmt_bind_param()</strong></span> in this cases.

<p class="para">

If a variable bound as INTO variable to an SQL statement was used before, the content of this variable

<span class="function"><strong>maxdb_stmt_bind_param()</strong></span>.

<p class="para">

For INOUT parameters of database procedures the content of the bound INOUT variable is overwritten by the output
