The OCILob class

(PHP 5, PHP 7, PHP 8, PECL OCI8 >= 1.1.0)

简介

OCI8 LOB functionality for large binary (BLOB) and character (CLOB) objects.

注意:
The OCI-Lob class was renamed to OCILob in PHP 8 and PECL OCI8 3.0.0 to align with PHP naming standards.

class OCILob {

/* 方法 */

public append(OCILob $from): bool

public close(): bool

public eof(): bool

public erase(?int $offset = null, ?int $length = null): int|false

public free(): bool

public getBuffering(): bool

public import(string $filename): bool

public load(): string|false

public read(int $length): string|false

public rewind(): bool

public save(string $data, int $offset = 0): bool

public seek(int $offset, int $whence = OCI_SEEK_SET): bool

public setBuffering(bool $mode): bool

public size(): int|false

public tell(): int|false

public truncate(int $length = 0): bool

public write(string $data, ?int $length = null): int|false

public writeTemporary(string $data, int $type = OCI_TEMP_CLOB): bool

}

OCILob::append — Appends data from the large object to another large object
OCILob::close — Closes LOB descriptor
OCILob::eof — Tests for end-of-file on a large object's descriptor
OCILob::erase — Erases a specified portion of the internal LOB data
OCILob::export — Exports LOB's contents to a file
OCILob::flush — Flushes/writes buffer of the LOB to the server
OCILob::free — Frees resources associated with the LOB descriptor
OCILob::getBuffering — Returns current state of buffering for the large object
OCILob::import — Imports file data to the LOB
OCILob::load — Returns large object's contents
OCILob::read — Reads part of the large object
OCILob::rewind — Moves the internal pointer to the beginning of the large object
OCILob::save — Saves data to the large object
OCILob::saveFile — 别名 OCILob::import
OCILob::seek — Sets the internal pointer of the large object
OCILob::setBuffering — Changes current state of buffering for the large object
OCILob::size — Returns size of large object
OCILob::tell — Returns the current position of internal pointer of large object
OCILob::truncate — Truncates large object
OCILob::write — Writes data to the large object
OCILob::writeTemporary — Writes a temporary large object
