<para>
|
|
Binds an SQL statement parameter to the specified variable name. The SQL statement
|
|
parameter can either be a named placeholder or a question mark placeholder.
|
|
</para>
|
|
<para>
|
|
Output parameters will set the value of the bound PHP variable to the value
|
|
returned by the database when the SQL statement is executed. This enables you
|
|
to call stored procedures with output or input/output parameters, for example,
|
|
for databases that support such features.
|
|
</para>
|
|
<para>
|
|
For input-only variables, you can pass an array of input values to
|
|
<function>PDOStatement::execute</function> instead.
