ibase_blob_open

Name

ibase_blob_open — Opens a BLOB for reading

Synopsis

int ibase_blob_open(blob); string blob: BLOB's internal ID in database

Returns

BLOB handle, FALSE on error

Description

Opens a BLOB for reading its contents in chunks with ibase_blob_get() . You obtain the correct value for blob by doing a SELECT query and fetching the respective BLOB column's content.

Remember to always close the BLOB with ibase_blob_close() after you have done with it, or you risk losing data.

In many cases it's simpler to just set the flagIBASE_TEXT when using ibase_fetch_row() or ibase_fetch_object() and retrieve a BLOB's contents directly into an array element or object member.

Note

Available in PHP 3 since 3.0.7, PHP 4 since 4.0RC1

Example

Example 535. See example for ibase_blob_get(), above
