示例 #1 A Phar::count() example
<?php
// make sure it doesn't exist
@unlink('brandnewphar.phar');
try {
$p = new Phar(dirname(__FILE__) . '/brandnewphar.phar', 0, 'brandnewphar.phar');
} catch (Exception $e) {
echo 'Could not create phar:', $e;
}
echo 'The new phar has ' . $p->count() . " entries\n";
$p['file.txt'] = 'hi';
echo 'The new phar has ' . $p->count() . " entries\n";
?>
以上例程会输出：
The new phar has 0 entries The new phar has 1 entries
