# PharFileInfo->getCRC32

(no version information, might be only in CVS)

PharFileInfo->getCRC32 -- Returns CRC32 code or throws an exception if not CRC checked

## Description

int PharFileInfo->getCRC32 ( void )

This returns the crc32() checksum of the file within the Phar archive.

## Return Values

The crc32() checksum of the file within the Phar archive.

## Errors/Exceptions

Throws BadMethodCallException if the file has not yet had its CRC32 verified. This should be impossible with normal use, as the CRC is verified upon opening the file for reading or writing.

## Examples

Example 1. A PharFileInfo->getCRC32() example

`<?php try { $p = new Phar('/path/to/my.phar', 0, 'my.phar'); $p['myfile.txt'] = 'hi'; $file = $p['myfile.txt']; echo $file->getCRC32(); } catch (Exception $e) { echo 'Write operations on my.phar.phar failed: ', $e; } ?>`

The above example will output:

    3633523372
