oci_bind_array_by_name — Binds a PHP array to an Oracle PL/SQL array parameter
$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.
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), but
SQLT_NUM
type 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.
成功时返回 TRUE
, 或者在失败时返回 FALSE
。

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.

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

Note that it looks like you can't bind a multi-dimensional array with this method. If you try, you'll get a Notice about Array to string conversion, and your PL/SQL will end up with a one-dimensional array filled with the a lot of string values, all saying "Array". :|
