PHP Manual: ZipArchive::addFile

Description

public function ZipArchive::addFile(
    string $filepath,
    string $entryname = "",
    int $start = 0,
    int $length = ZipArchive::LENGTH_TO_END,
    int $flags = ZipArchive::FL_OVERWRITE
): bool

Adds a file to a ZIP archive from a given path.

Note:
For maximum portability, it is recommended to always use forward slashes (/) as directory separator in ZIP filenames.

Parameters

filepath: The path to the file to add.
entryname: If supplied and not empty, this is the local name inside the ZIP archive that will override the filepath.
start: For partial copy, start position.
length: For partial copy, length to be copied, if ZipArchive::LENGTH_TO_END (0) the file size is used, if ZipArchive::LENGTH_UNCHECKED the whole file is used (starting from start).
flags: Bitmask consisting of ZipArchive::FL_OVERWRITE, ZipArchive::FL_ENC_GUESS, ZipArchive::FL_ENC_UTF_8, ZipArchive::FL_ENC_CP437, ZipArchive::FL_OPEN_FILE_NOW. The behaviour of these constants is described on the ZIP constants page.

Return Values

Returns true on success or false on failure.

Examples

This example opens a ZIP file archive test.zip and add the file /path/to/index.txt. as newname.txt.

Example #1 Open and add

<?php
$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {
    $zip->addFile('/path/to/index.txt', 'newname.txt');
    $zip->close();
    echo 'ok';
} else {
    echo 'failed';
}
?>

Notes

Note:
When a file is set to be added to the archive, PHP will lock the file. The lock is only released once the ZipArchive object has been closed, either via ZipArchive::close() or the ZipArchive object being destroyed. This may prevent you from being able to delete the file being added until after the lock has been released.
