OCI-Lob::writeToFile
We were able to get the example included for the "OCI_BIND_ARRAY_BY_NAME" to work. However, the example is NOT actually binding with a PL/SQL array of any type. It is writing data to an Oracle table named "bind_example". Notice how this table is created. The table does NOT have an array type as one of its fields. Since this is the case, there cannot be any binding to a PL/SQL array because at least one field in the table must be either a VARRAY, NESTED TABLE or ASSOCIATIVE ARRAY data type. We searched the Internet and could not find any examples that actually read from a PL/SQL array type. We were able to get data from a PL/SQL VARRAY data type, but only by using a SELECT statement.
oci_bind_array_by_name
(PHP 5 >= 5.1.2, PECL OCI8 >= 1.2.0)
oci_bind_array_by_name — Binds a PHP array to an Oracle PL/SQL array parameter
Description
bool oci_bind_array_by_name
( resource
$statement
, string $name
, array &$var_array
, int $max_table_length
[, int $max_item_length = -1
[, int $type = SQLT_AFC
]] )
Binds the PHP array var_array to the Oracle
placeholder name, which points to an Oracle PL/SQL
array. Whether it will be used for input or output will be determined at
run-time.
Parameters
-
statement -
A valid OCI statement identifier.
-
name -
The Oracle placeholder.
-
var_array -
An array.
-
max_table_length -
Sets the maximum length both for incoming and result arrays.
-
max_item_length -
Sets maximum length for array items. If not specified or equals to -1, oci_bind_array_by_name() will find the longest element in the incoming array and will use it as the maximum length.
-
type -
Should be used to set the type of PL/SQL array items. See list of available types below:
-
SQLT_NUM- for arrays of NUMBER. -
SQLT_INT- for arrays of INTEGER (Note: INTEGER it is actually a synonym for NUMBER(38), butSQLT_NUMtype won't work in this case even though they are synonyms). -
SQLT_FLT- for arrays of FLOAT. -
SQLT_AFC- for arrays of CHAR. -
SQLT_CHR- for arrays of VARCHAR2. -
SQLT_VCS- for arrays of VARCHAR. -
SQLT_AVC- for arrays of CHARZ. -
SQLT_STR- for arrays of STRING. -
SQLT_LVC- for arrays of LONG VARCHAR. -
SQLT_ODT- for arrays of DATE.
-
Return Values
Returns TRUE on success or FALSE on failure.

Example #1 oci_bind_array_by_name() example
<?php

$create_pkg = "

PROCEDURE iobind(c1 IN OUT ARRTYPE);
END ARRAYBINDPKG1;";
$statement = oci_parse($c, $create_pkg);
oci_execute($statement);
$create_pkg_body = "
CREATE OR REPLACE PACKAGE BODY ARRAYBINDPKG1 AS
CURSOR CUR IS SELECT name FROM bind_example;
PROCEDURE iobind(c1 IN OUT ARRTYPE) IS
BEGIN
FOR i IN 1..5 LOOP
INSERT INTO bind_example VALUES (c1(i));
END LOOP;
IF NOT CUR%ISOPEN THEN
OPEN CUR;
END IF;
FOR i IN REVERSE 1..5 LOOP
FETCH CUR INTO c1(i);
IF CUR%NOTFOUND THEN
CLOSE CUR;
EXIT;
END IF;
END LOOP;
END iobind;
END ARRAYBINDPKG1;";
$statement = oci_parse($c, $create_pkg_body);
oci_execute($statement);
$statement = oci_parse($c, "BEGIN ARRAYBINDPKG1.iobind(:c1); END;");
$array = array("one", "two", "three", "four", "five");
oci_bind_array_by_name($statement, ":c1", $array, 5, -1, SQLT_CHR);
oci_execute($statement);
var_dump($array);
?>

This function appears to work with PL/SQL associative arrays (index-by tables) but I was unable to get it to work with PL/SQL varrays
