int OCIBindByName(int stmt, string ph_name, mixed &variable, intlength, int [type]);OCIBindByName() binds the PHP variable variable to the Oracle placeholder ph_name. Whether it will be used for input or output will be determined run-time, and the necessary storage space will be allocated. The length paramter sets the maximum length for the bind. If you set length to -1 OCIBindByName() will use the current length of variable to set the maximum length.
If you need to bind an abstract Datatype (LOB/ROWID/BFILE) you need to allocate it first using OCINewDescriptor() function. The length is not used for abstract Datatypes and should be set to -1. The type 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).
Example 1. OCIDefineByName <?php
/* OCIBindByPos example thies@digicol.de (980221)
inserts 3 resords into emp, and uses the ROWID for updating the
records just after the insert.
*/
$conn = OCILogon("scott","tiger");
$stmt = OCIParse($conn,"insert into emp (empno, ename) ".
"values (:empno,:ename) ".
"returning ROWID into :rid");
$data = array(1111 => "Larry", 2222 => "Bill", 3333 => "Jim");
$rowid = OCINewDescriptor($conn,OCI_D_ROWID);
OCIBindByName($stmt,":empno",&$empno,32);
OCIBindByName($stmt,":ename",&$ename,32);
OCIBindByName($stmt,":rid",&$rowid,-1,OCI_B_ROWID);
$update = OCIParse($conn,"update emp set sal = :sal where ROWID = :rid");
OCIBindByName($update,":rid",&$rowid,-1,OCI_B_ROWID);
OCIBindByName($update,":sal",&$sal,32);
$sal = 10000;
