<para>
<function>ocibindbyname</function> binds the PHP variable
<parameter>variable</parameter> to the Oracle placeholder
<parameter>ph_name</parameter>. Whether it will be used for
input or output will be determined run-time, and the necessary
storage space will be allocated. The
<parameter>length</parameter> parameter sets the maximum length
for the bind. If you set <parameter>length</parameter> to -1
<function>ocibindbyname</function> will use the current length of
<parameter>variable</parameter> to set the maximum length.
</para>
<para>
If you need to bind an abstract Datatype (LOB/ROWID/BFILE) you
need to allocate it first using
<function>ocinewdescriptor</function> function. The
<parameter>length</parameter> is not used for abstract Datatypes
and should be set to -1. The <parameter>type</parameter> variable
tells oracle, what kind of descriptor we want to use. Possible
values are: OCI_B_FILE (Binary-File), OCI_B_CFILE
(Character-File), OCI_B_CLOB (Character-LOB), OCI_B_BLOB
(Binary-LOB) and OCI_B_ROWID (ROWID).

<note>
<para>
This function was renamed to <function>oci_bind_by_name</function>
after PHP >= 5.0.0. For downward compatibility
<function>ocibindbyname</function> can also be used.
This is deprecated, however.
</para>
</note>
<warning>
<para>
It is a bad idea to use magic quotes and
<function>ocibindbyname</function> simultaneously as no quoting
is needed on quoted variables and any quotes magically applied
will be written into your database as
<function>ocibindbyname</function> is not able to distinguish
magically added quotings from those added by intention.
