PHP | zip_close( ) Function

The zip_close() function is an inbuilt function in PHP which is used to close a zip archive file opened by the zip_open() function. The zip_close() causes the stream to be closed and the connection to the corresponding Zip Archive to be broken. The zip resource which has been opened by the zip_open() function is sent as a parameter to the zip_close() function and it returns no value.

Syntax:

void zip_close ( $zip_file )

Parameters: The zip_close() function accepts single parameter $zip_file. It is a mandatory parameter which specifies the zip file resource to be closed.

Return Value: It does not return any value.

Errors And Exceptions:

• The zip Archive to be closed must be opened first by using the PHP zip_open() function otherwise the PHP zip_close() function produces a PHP warning.
• The zip_close() function returns an ER_OPEN error if the zip archive is invalid.
• The zip_close() function returns an ER_NOZIP error if the zip archive is empty.
