PHP“Crypt_Blowfish"类初始化错误

我的PHP Crypt_Blowfish类初始化抛出以下错误:

Strict Standards: Non-static method PEAR::raiseError() should not be called statically, assuming $this from incompatible context in /usr/share/pear/Crypt/Blowfish/MCrypt.php on line 155 Strict Standards: Non-static method PEAR::isError() should not be called statically, assuming $this from incompatible context in /usr/share/pear/Crypt/Blowfish.php on line 199 Strict Standards: Non-static method PEAR::isError() should not be called statically, assuming $this from incompatible context in /usr/share/pear/Crypt/Blowfish.php on line 142

<?php
include_once('/usr/share/pear/Crypt/Blowfish.php');
$cipher = new Crypt_Blowfish("_mysalt_");
?>

• 是因为include吗?但是当我禁用include时，它再次给出:

错误:Fatal error: Class 'Crypt_Blowfish' not found in /var/www/html

那么什么是严重的错误呢?

• 现在我很困惑，如何使用Crypt_Blowfish类请?(我是否正确启动它，或者是否有其他标准的方式来使用/启动它?)
• 或者，使用该类的要求是什么?(我在RHEL上运行了这两个安装。yum install php-pear-Crypt-Blowfish和yum install perl-Crypt-Blowfish。Apache重新启动。我还错过了什么吗?)

请帮忙!
