Closes an open BLOB created with ibase_blob_create() or accessed with ibase_blob_open() . All BLOBs opened during your programs execution must be closed, and all BLOBs created either closed or discarded with ibase_blob_cancel() . Otherwise you risk losing data.
Remember that you also must close a BLOB before inserting it into the database or replacing a BLOB column's contents with a new BLOB. The string returned by this function is what you use with INSERT or UPDATE queries.
If the return value is FALSE, something bad happened (for example, no free space on disk) and if the BLOB was created for writing with ibase_blob_create() , you must discard it with ibase_blob_cancel() .
Available in PHP 3 since 3.0.7, PHP 4 since 4.0RC1
Input parameter blob will change its type to resource in the future.
