# OCIBindByName

OCIBindByName -- Bind a PHP variable to an Oracle Placeholder

## Description

`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).
