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

说明

int PharFileInfo->getCRC32 ( void )

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

范例

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;
